ABANDONED Dodge Challenger Rescued After 35 Years Part 18: Hemi and 4 Speed Transmission!

Jun 10, 2021
If I wet sand a lot of those spots and I realize that you know about 85% of the original paint is still on that car, so to make this project happen we were going to go through a few different stages of sanding this paint. Overall you know it looks a lot better than this primer that was here so you can hear the difference in the primer alone. Just listen to that compared to just a few packs of sandpaper, a little water and some time we can get a lot back and that original paint shine we got ourselves a new motor mount and it has no motor luckily I have this special delivery outside look at this other Hemi so this right here is very exciting this is a 2006 5.7 liter Hemi from a Jeep Grand Cherokee now you remember I talked in a previous episode about us going with a 2015 Jeep Grand Cherokee engine and the reason why I ended up using this one because it's not a VVT engine or a non-variable valve timing engine, it's the pre Eagle situation where they do a lot of upgrades to the engine over the last few

years

but don't really have much aftermarket support for the Moment, there are factory style harnesses and all that good stuff, but I wanted to run a standalone one.

ECU harness that didn't have to use a factory harness because I want to be able to tune the engine and that's where luckily Holley is going to step in and give us their finished eggs for a non-TVP Hemi and we're going to use it to tune this engine and set it up like true plug-and-play. I'm excited, we'll go through it in just a minute, but this engine has 64,000 miles on it and what happened was the Jeep got rated I. I'm sitting on it so the engine didn't suffer any damage. They started it before taking it out.

More Interesting Facts About,

abandoned dodge challenger rescued after 35 years part 18 hemi and 4 speed transmission...

It was a local junkyard that Hank has known for

years

. I've had an amazing experience using their

part

s before so I've Don't worry about this motor here and basically the plan is to install it as if it were a couple of upgrades. I know there is speculation about why the cams fail or if they are a really big problem, but I think. A lot of this is attributed to the fact that maintenance is a big thing on these engines, they use such a light oil with these kinds of tolerances and if you skip oil changes you know the stuff is going to burn, it's going to be cool, it's going to clog. any type of system and you don't change the oil often enough, then yes, it will cause things to fail and also these things run much hotter than seen in the past.

It has a thermostat of 203 degrees and the main thing is that the engine as a whole stays hotter, that way it will be more efficient, it will heat up the combustion chamber much more, it will burn more fuel and that is not the case. More environmentally friendly, it will consume more fuel, but I won't turn it down to 180 degrees to prolong life because what you don't realize is that you know you could be burning fuel more efficiently, but at what cost? You're starting to really damage all the components around the edge of the crack which is causing it to get so hot so let's fix that and I'd like to do a cam swap before the thing goes into the car it just depends on what we are going through and I had no doubt that this engine will go down just when we are missing the AC compressor and the alternator will get it so we just have to put a belt on it we will clean everything and you I know the engine should run if you change the cam We will change the distribution chain.

The Holley Terminator X EFI system is really simple. You could plug it in and give power to that box and that's it. I can literally shoot straight and be ready. to go, so that's what I like. I have to change this throttle body. This is a cable drive. We have to change it to a cable operated throttle body. It's not a big deal or to have everything in order and we have. everything to get the fuel system working to finish, we have the tank sink and if I take the EFI fuel pump system in the back, all we have to do is route it to the front of this thing, we have everything in order, we have everything in working order, I changed the oil pan to the monotron system.
I'm going to make all of that happen and I have supports on the way for the conversion, so everything is snowballing at the moment, we have a lot of really interesting pieces. that they're coming for this and we're going to put it behind a new energy for us, at least a

transmission

that lands here on the floor, we'll talk about that in a second, but what I'm going to do in this video is kind. To compare this engine to the small block that came out of the car, I don't have the exact one, but I have a 360 here in the booth and I wanted to talk about what the differences are, what the similarities are and how.
Is it easy to change one of these on your car? I want to show you step by step basically in the next few videos what you're going to see and how simple it is to put one of these in your car if you want to and I. I want to remove the valve cover to see what the inside looks like. I want to remove the intake as well to see if we have the MDS system, which is a Chrysler and cylinder deactivation. Basically, we are in low load situations that will redirect the oil. and lifters to deactivate those four cylinders where they don't open the intake valve and then they only run in four cylinder mode, thus being more efficient and I want to deactivate that and that's where the cam shift would really help in that situation, but of all Anyway let's start taking this a

part

and see what we have.
I already unscrewed our cold packs here, take them out, throw them here out of my way, let them ruin them, we can reuse all that sounds fuller, the valve cover looks pretty clean, no. oil build up or something like that, I mean there's no sludge so it looks like they at least took the time to change the oil so that's a good sign we don't have any build up here on the bottom side where the oil likes you like the old oil it would like to build up if you don't you don't like it I've changed correctly so everything seems to be in order at least no loose rockers or things like that so that's a good sign.
I like what I see below. Here's a closer look for you guys to really see how clean it is inside. Very happy. Very good sign. I love the wet look so I want to remove the entrance and see what the valley looks like and see if we have MDS or not. I have the plugs under there. I'm guessing coming out of a Jeep Cherokee it's going to have an MDS, but you know, you can always hope, so we loosen all the bolts, get everything out of the way, all we have to do is lift this thing up. bad boy here it would help if you loosened the bolts all the way there we go and we have MDS and you said this entry is done and looks better so you've heard me talk about MDS now what that means is multiple offset. system, so on those four cylinders there you can see the actuators, what this does is a light rpm cruise, it will turn off four cylinders, so it will basically run on four cylinders and it's been four economy, all that good stuff that I don't want.
I want to make sure we disable it, so what we're going to have to do is remove all of these sensors and this harness from here and replace them with plugs, so that's one of the main reasons why it was necessary to take off. Firstly it was to see if we are on NBS and here is Holley's Terminator What you see here are quite a few things that we have implemented in each part of the harness that is needed to make a motor work at each step. a little bit of add-on you're going to need, this is a bunch of really cool stuff we have here, this is the power cable for your battery and the one that comes with it.
I mean, I checked, it comes with every harness, the add-on you need. these are also labeled so it's easy to find so you've got the cam angle sensor right there it says cam there's the crank sensor and this says the crankshaft liner comes with this heat shield wrap we have even a Fan Relay built into this we don't have any built in sensors with the crank sensor right there you see it on the outside of the crank and then this is to adapt our Oh sensor to the and it comes with a two Bosch Oh sensor to the right. here hot a coat control sensor right there all the injectors all the coil paths everything is here it's all you need I already put it on the engine to test I have a photo here I'll show you guys, but I already put it there just to make sure everything works and on top of all that in this box here are the controller oil packs so all you do is plug it in it's that easy plug it into the harness for the coil pack and voila, there are two, one for the driver's side and one for the passenger side cylinders.
Here is our controller box. You plug it in and then you have power. That's all you have to do. It's so simple. Literally guys they are so simple it doesn't get any easier than that so you know you can do this with a factory style harness but the thing is Holley offers this and it gives you so much extra adjustability it's crazy . it's already set up and you can have this ready to push, you can do whatever you want and here's our little screen that will show us what we've done and they put a nice little stand on it so you can you can just put it in the car, it matters where you want that it is and then just set it up, you know, have it where you can see every little detail about the engine.
I'll tell you everything the sensors say, which one it is. your oil pressure tent, all of that, you feel pressure to make sure that all of that is maintained and that's why I'm really excited about this harness from Holly so thank you all Holly, you got it great. This will be a really cool build. and a really cool setup that's easy to use and that I'm really excited about, so in addition to being able to choose the engine for the Challenger, solving a really big piece of the puzzle with the

transmission

. What is this? It's an 833 transmission.
It's a four-

speed

, which means it has four gears, but our final drive ratio is not one to one as was the case with the four-

speed

transmissions or the three speeds that the car has and what I mean one on one. The relationship is that you have three thousand rpm coming from the engine, which is equivalent to three thousand rpm coming from the rear axle to all four wheels. We have this overdrive unit that, instead of having a one-to-one final drive ratio, it's point seven three. final drive ratio and what that tells us is that we have to put in about three-quarters of the effort to maintain that one-to-one ratio down here, so, for example, if we want to maintain three thousand rpm at the tailshaft We're looking for around 2200 engine rpm and what we do is because it's a fuel burner that greatly reduces the amount of wear and tear on the engine and prolongs the life of the engine and all the components around it because you're not having to work so hard to maintain the same speed and we can run down the interstate at 80 miles an hour with no problem, it reduces the noise inside the car it just makes everything so much better now what this is is a truck overdrive, this is a aluminum case with overdrive, compared to what the three and four speeds would normally do is to have a cast iron body, that somehow affects the amount of power that we will be able to transmit through the engine to a To the extent that I have personally seen these transmissions last behind the soft big block for years, no problems, the Hemi basically in stock form is what you want over the big block, to some extent the same power output won't be a problem.
I think we will be. Totally fine, now the gear spacing is not ideal compared to a four speed, this one has a very low first gear, things like 3.09 or something, and then you go into that second gear, it's quite wide because you have to compensate for that third. the gear gap is one to one so there is a big RPM drop from first to second gear but otherwise it's a good transmission now there are some cons and some pros but overall I think we have really good setup here and this one has been taken apart, cleaned up new gaskets, even took apart the shifter mechanism and really cleaned everything up and made it look nice, new boot on the bell housing, that's all really good, Although we are going to use many of these things.
You have to change the city axles on these transmissions. You can see that you can mount the shifter here or here. Then when the

challenger

s came along in 1970 they started making a dual pattern rear axle which means they have this location like a B body or a truck because that's when you see those really long pistol grip shifters and like a charger or a roadrunner versus the Challenger which has a very short one because it brings the shifter location much closer to the driver and these are not drilled, no I don't have to drill them and I have a backup rear axle that I bought the same day in case I mess it up, so it's already drilled but doesn't have all new seals. so I want to try to drill this one and it already has all the thingsnew, it's clean and another thing we'll have to change is the shift lever rods.
I'll have to move the shifter back to fit the hump in the floor. from the Challenger and get shift rods and then make the appropriate modifications to make it all work, that's no big deal, everything is available, we're going to be able to pick up all that stuff, but at least we have the basis to do it. One more thing works. You see, I have an extra bell right here. This is a slanted six bell housing that houses the bracket like the Chrysler six cylinder and will not fit our Hemi if you remember some videos from a long time ago, every time I announced that I was going to put one on the Challenger?
I installed a small block bellhousing on our Hemi and this is what since this is a v8 overdrive transmission bridges the gap between that and as a rate before speed is the size of the bearing retainer this one has a larger diameter bearing retainer which means you have to machine your existing 4 speed direct small block bellhousing or get an overdrive bellhousing and I belonged. on the market generally the transmission I paid $300 for everything done, I just found a good deal at the swap meet, I paid $50 for the bell. I have an extra transmission and that rear axle I mentioned with the dual pattern.
I paid 180 for both so overall I have very little and what I have to do for this transmission, you know, I can't install this transmission here for at least 350 dollars if I already had the shifter linkage and everything. set up but we're going to have to get some things done, it's not a big deal but having overdrive and four gears isn't a bad setup since the cars are already manual this will be simple now, at first glance the Hemi looks huge. Compared to the original small block, but let's take a closer look now, obviously the Hemi has a much wider cylinder head, but it doesn't have one that is as tall.
That's really the big difference: you can see what the first La-style model looked like. The stock is much taller, it will rise to a certain point, basically this one is very flat and much wider. I want to measure the cylinder head surface mounting pad on the Hemi versus the small block, which you'll see, Ralph, on the right. Here entertainment or else, we get it as close as we can, looking at where the solar head is screwed to a foot and swinging sharply. Head Coach's Manual. We come here for the small block, let's see what we have here, we have one.
The foot looks like six and a half, they're balanced, so this one is actually physically wired compared to the new style Hemi. Now the block itself is this thing is definitely bigger for earlier hands, but this one is physically wider if you're worried. fits inside your inner fenders this one, if this one fits, that one doesn't fit and again, the Hemi engine is a little more dressed up compared to our 360 here, but you can see that as far as accessories go, there really isn't much of the timing cover difference is much larger on the Hemi because it's basically that entire section versus the smaller timing cover on the small block, but what we compensate for is the fact that this is a serpentine system, so with this serpentine system the pulleys are much tighter against the engine than that so you have a lot more room to work with in the front so that's where the payoff is and plus the Hemi already comes with turbo headers. aluminum, fuel injection, full roller cam, everything. that you need to make a fun little car and have it all original, it's all uphill from here at this point where the 360 ​​lacks all of that, that doesn't mean the small block still doesn't have its place.
I love these engines. what I learned and I have a great passion for these little things and I want to show you guys that it is easier than you think to change all this, so to be fair, let's measure the widest point of the valve cover for the Hemi versus the small block looks to be about two feet three inches on that one let's go to the small block and see what we have and it's one foot eight inches so yeah you can see there's a lot of difference if how In terms of width these engines are They compare to each other, but there's still not much difference to get to a point where you can't put this on one of these cars, so as you can see, we have a lot of things to achieve.
You have a lot of great parts and we have basically everything to finish the car so you better come back next week and see what we're doing because next week's video is going to be amazing, let's apply. Many of these parts are finally here and we can't wait, so thank you very much for watching. If you liked the video, please leave a like below. If you have a question for me, feel free to leave a comment. order your t-shirts and stickers submit your projects to the facebook pages at the end of the video and I appreciate everything you have done for me and it looks like our dream is finally coming true with this 4 speed Hemi. so thanks again see you next time
