Tiny Old HEMI - First Generation 241 Hemi on DYNO

Feb 27, 2020
and this is the smallest engine I've ever had here on the

dyno

, 241 cubic inches and it happens to be a Hemi and here we have it a 1954 Dodge Royale pace car convertible with a 241 Hemi, which is due to the fact that it had a power of 150 horsepower. Of course, it took us a while to get this engine on the

dyno

bucks. I want to find some pieces, we have some pieces here and there and I also have some pieces out of nowhere and we finally put them together and of course. This is not an engine that is very easy to install on the dyno, we had to do a lot of fabrication, for example for the engine mounts, they don't have lugs on the side of the block to connect my engine mods like any typical v8, but so we made a support or a bridge, as you call it, that is under the water pump.

My friend Dan was at the shop the other night and I told him I wanted to build something there to put this engine on the dyno because for the factory there is a bridge so it's a fun looking part that I don't have so I told him if we could do something so I can put it on the dyno so I can do some testing on this red 2:41 Ram Hemi, so it stayed anyway. here one night with me we got a real piece of metal of course we made it and here it is we made it and finally we put it on the dynamometer bracket and then another complication we got very lucky with the bell housing. the 340 L is a one inch engine or small block and a Mopar right here bolts up to the block shell in the 241 year so I got lucky with that but the only problem is these engines only come with an automatic transmission, as far as I know, then we had a problem with the fire wheel with its bow casing, but again the resistance of the firewood bill is so great that it does not fit inside this navigation, so I noticed that the crankshaft On this engine was an 8 bolt crank and then I needed a smaller flower wheel like 130 teeth, so luckily I tried the Hemi flywheel that I have on my dyno to test Hemis, which is a small 130 tooth flower wheel that was aligned with the eight crank bolts that had been bolted right here on this engine and it worked fine and again we had the problem with the starter motor and the teeth aligning the flywheel so we had to space the block and after that we lined it up perfectly , we had to space the starter like this then we added some washes here like this here then we have to make the brackets and then of course this is what comes with the car for the flywheel, it's actually a torque converter that I cut up to talk about it.

I had a spare one, but again I had to center the holes to go to my friction plate for the dyno, then we took a part of course, the talk about the order to align it, then I said, you know what this is not positions of work too big, it's I hit the bell housing on the LA 340 engine and it didn't work, so I said, you know, let me try something else and this is where I thought about putting the steering wheel, hey me, and I noticed that the eight bolts were exactly like a Hemi so we put it on and of course there's no threaded flywheel we put on bolts and nuts so we got it so I went to a bolt shop I got from a street place here and there, we did so that was another case and then I had a dealer here is the Subaru I looked at.

I go, you know what this is a mess, you know, I know it works with points, okay, so I said, you know what I'm not going to sit here, try to fix this and I noticed that you also wanted to buy a Ronix pet kit , but I thought of something else. I took a look at a 340 electronic distributor here. This is exactly what I bought here. 72 73 340 electronic distributor, of course, I can't form a 340 Motor and look it bolts it perfectly, so once we set up the flywheel, once we have the bike, to hold the motor once we turn on the distributor, then Of course we have the wiring, this is what comes in a ceramic 241 Hemi or whatever.

I don't know I couldn't find a set of wires at the time I put the engine on the dyno so what I did was take a set of wires from a 426 Hemi and like you I can see I installed them like a 426 Hemi and He did the job. There's a bit of a loose fit here, but it doesn't matter, it still looks like Knapp on the spark plug and that's what counts, and then I thought there was quite a bit of disagreement. I installed valve covers the other day I took out some red paint with a brush and put it to the side or 1/8 and started painting the Red Ram and Dodge and Wolf Courts lettering to give it a better look but that's the way .
It came from the factory so I sat there with a little brush and did some touch ups just to give it a better look and here it is. I know I couldn't find a stencil kit on the market that I could glue or find. way to do it, so I did the best I could with what I had, the valve covers are so pitted and rusted that you couldn't even read the name in some cases, of course some of the parts are almost flat, but I try to copy which This is a better box cover on the other side, so I copied it so that it was, of course, like cufflinks.
I did it and this is the result, but you know, putting this engine on the dyno was something you know, playing with fire. The wheels were playing with the stand and of course this was also a problem but I finally figured it out. This Jupiter. I went to a 340 dealer. Now of course this is the housing that comes with it for the thermostat, which I don't use. Use the. one I use from the Adana mama all the time, which has a 90 degree angle, is factory facing up and that's the terminal housing I use for the dyno, but that wasn't a problem.
My biggest concern was setting it up and here's the carburetor. with a Hauser furnace intake manifold and this one from the factory I believe is a 150 or 160 horsepower engine, it is not modified in any way, it has been rebuilt to initial specifications and the only thing it had was a larger diameter than 30 and then the other part is the exhaust. system, of course, we do not have heads for 241 Hemi. I use the original exhaust manifolds, as we all know, there is nothing special, no disease, no smallpox, all I know is the way they were designed, they do not generate any power.
Check it out, it's such a small tube. and if you look at the other side it's even worse, look at that simple waffle pattern exhaust manifold, don't expect this to make any power with these manifolds as you can see the exhaust coming out of here and then the exhaust coming out of here, of course. You're going to lose power, all they do is crush each other. I try to get out the tube for free for a nice bite of professional exhaust. You need individual tubes as headers or a high performance manifold, but again in 1954, this is the The manifold II came with the engine with a very poor design, but of course we managed to put it back on the engine.
To run it on the dynamometer, we were able to check how the engine is doing by breaking the cam which, of course, we got to check the oil. check the pressure for leaks, check for noises, and of course check for vibrations. What surprised me, of course, these dentists also came with an intestinal tube and then had an upgrade as a distributor. I think the installation of a distributor with a furnace also takes for the panel configuration with the Hemi head, of course, maybe it has more compression ratio, but in reality it will have a seven point compression ratio, but you know, so Every thought of escape is our performance.
I don't know, but they never changed it, but this is a horrible design, but then again at 54 years old, who thought of that, and then I had another problem yesterday because when I had the engineer working I said, let me check, I'll tell you. you forgot the oil in the walkers because these are non-adjustable lockers and they were very, very dirty. Yesterday I took the valve cover off, we ran the engine without the top cover and there were very, very small drops of water coming out through the walkers, so friend and I took all the axles, dismantled everything and we have to blow air and the cleaner and every little rocker arm likes every little hole, which took us time to clean the shafts from the inside out, we started feeding more oil through the air pushrods into the rocker arm assembly and after that, we finished and put everything back on then did a rogers for a few seconds and finally saw the oil was splashing everywhere like it should so we put the valve cover back on then did some testing and then took it from there.
This is a unique oil filter, it's a 50's type cartridge. most engines with that cartridge didn't have spin-on oil filters so I thought you know I'm going to put their word on the adapter to fit a new cartridge and screw it on and I thought you must have an oil leak to Sure you know everything that is sold on this engine but surprisingly I have a low belt so everything went well and of course I had to prime the engine before install it on the dyno and I mean, it didn't have the same water pumps as the new one. modern LA 340 engine so I had to make my own axle so I could prime the engine and of course let me show you the whole Mopar range and the small and big blocks.
I primed them with this tool here, which is a hexagonal shaft so I put an electric drill and ran it through the oil pump and this alters the design when I prime the engine, but in this case it's a different world pump, it's more like the Chevy style that has a spline like this so I go in like I came out and I got a shaft put a spline on it put it in there in the oil pump through the distributor hole and primed it before I installed it and then when I got an oil pressure of 70 psi right at the time of the engine, I said to myself: we know what we are ready to run this on the dyno and we ran it and of course someone had the carburetor result for us and Of course there was actually a problem with the float because the fuel was just pouring into the engine because the float was stuck open so we took the top of the carburetor off which was an install last night and we fixed that as well and of course Of course, my client also bought in the oven.
We started with a soccer ball because that's what I wanted to execute. the angel

first

and we built the engine with everything that comes with it in short, it was a challenge, but I've never done an old Hemi on a dyno, you know, we had to go through so much work. You said it practically took us three times as long as any other V8 engine to get it on the dyno, but of course, you know I wanted to see how it's going to go, how it's kind of working, it was pretty impressive, it's an old engine, it was designed way before that I. was born so it was something you needed to see so we're going to warm it up we'll do a little test and yesterday I did some testing but I noticed that it runs poorly at full speed so I'll have to open it up.
Turn it back on and look at the jets, if they grow, if I just run this type of carburetor, we'll warm it up so you can see what it was like for an old 1954 engine brought back to life. and I also have the original shop manager that my client drove here is the Dodge shop manual, this is 1954 and of course I looked up the specs. I use this manual to do my job and here we are, we have a compression ratio of 7.1 and Of course, here is the maximum braking power at 4400 rpm. There's 150 in the Royale car, of course, right here, so when you have the Royale da GTL it's a 150 horsepower engine at 4400 rpm, so we'll do some dyno testing and see what. we're going to get like I said it's a factory built we copied exactly or what came from the factory without anything modified we just had it on the dyno of course the way we incorporate the weight it came from the factory so let's see what we're going to get to get it, so let's heat it up.
Start testing and we'll take it from there. Let's see for 245 Cubans 3.4 67 for 250. Okay, just what we're going to execute. I have to make sure the choke doesn't close on me. When I do the full throttle test so you can see what I can do with this, you guys want to know an interesting fact: the person, the lady who bought this car new in '54, is still alive today, she is 99 years old and she is the indicated one. who bought this car new with her husband back in 1954. I hope you watch this video and listen to what I say and of course I don't know your name, but it's cool that you just sold this engine to this client of mine, so when watch the video and see this thing come back to life, bought it again in 54 new and thanks for doing all the old changes back then, for that reason the hinge is still alive, the only thing I just need a little rebuild, Machen Addy.
You see something come back to life after so many years. Go crazy, let me tell you, they bought this car new, you know? And this is a touch to me because they know they don't. Meet this lady I bought this brand of car. She would love to see this working or, if she can't come here, of course, she could see that she is running in our video and, of course, have someone tell her about it and thenthrough the tunnels or whatever port you go to, whatever it's called. I'll see what my client wants next, we can take it. from there, but in the meantime we got a little runny nose, everyone is fine, we have no legs, we have no vibrations of any kind if it's okay, what fish is good, no turkey noises and of course we have a normal life , which really surprised me, which is great, no leaks whatsoever and of course.
This is a 1954 engine. I think we did a great job for the
