today we're taking care of all you mopar fans with an rb or rise

block

big block construction that will use the latest parts in the Today's aftermarket we satisfied them Big Block Chevy fans built a 572-inch anvil that made horsepower off the gas straight from the pump and then wowed the Big Block Ford crowd with a blue oval bad boy from 557 inches that made the internet buzz. we doused it with a 300 nitrous shot to set an awesome graph on our superflux holy cow 1080 horsepower and 1119 torque and still pump gas all with a two bolt main block snug like many of you needed a proper Core to start with, so we called in the Mopar pros at Stevens Performance in Anderson, Alabama.

Now we tell them about our plans for this

and they took the opportunity to help us. They pulled this 440 out of a pair. His car took it apart to make sure the block had no obvious damage and then shipped everything to us in a couple of boxes. buffed line matching and squaring the covers and also drilling and then buffing the cylinders with torque plates removing the two bolt main caps will free the crank it is always good practice to loosen them from the outside in which is the reverse order of torque to when it was assembled, the crankshaft casting number is 2206160, making it a forged steel part.

We are revving this

engine

to over 500 cubic inches so we will be putting this on our parts gauge for another build in the future, now we can see the casting number designating this block as 1966 to 1972 and the actual casting date is out. right above it 12 21 of 71. so this block is from 1971. here's something you don't see every day the crank was resting on the original 197 1 bearings. 9.7-to-1 compression and was equipped with a 4-barrel carburetor now this thing made 370 horsepower with 480 pound-feet of torque, making this the last year for one of the big-horsepower engines they produce muscle car now off to shacklet's auto for a cool down after a few days in the machine shop our base mopars is back in our hands while at shacklet's automotive our block it was a tuned line it gets all the main bearing holes lined up and sized we supply these arp bolts because they had to be in this operation every time you switch from bolt to bolt it will distort the main cap differently because of the way the fastener actually clamps the cap and then the decks were evened out which puts the height and flat of the decks the same distance from the center line of the crank after that the cylinders were bored and then honed using a torque plate that is tightened to the platform to simulate a cylinder r head fitted this allows the cylinder to be honed in a controlled manner to maintain proper plate geometry all machining steps were performed to the best of its ability showing that shacklets is a quality shop but before we can put it in the cleaner We still have a bit to do and since it will be a 512-inch street bullet, the tra We'll tackle accordingly, which starts with a grinder and carbide burr to remove the casting burr from the riser valley.

These thin areas have been known to flake off and migrate right into the oil pump, so we get rid of them. Next, we will smooth the oil inlet into the block along with the oil holes that feed the electrical network. We eliminate sharp edges anywhere oil flows. Reduces turbulence, which increases. flow, since this block was thermal cleaned, it is imperative to go ahead and clean all the oil galleries very well. Here's a little tip you always want to make sure you clean the block you're working on yourself because you never know what might be left on it now we like to use this 10 piece brush kit you can pick up direct from goodson now you can use it as is or here is a little tip we cut the ring off the end of the handle and for good reason it allows us to throw it in a drill so the galleries can be cleaned faster by blasting wd-40 on the bristles which starts the cleaning work the brush along the entire length of the gallery the purpose is to loosen remove any foreign matter that may be in them but don't stop there be sure to clean as many oil passages as possible hence the different size brushes in the kit, the final step is to wash the whole block, we will be back in line, yes.

Sir, everything is working great. Welcome back, now it's time to assemble the short block. Now, the swivel assembly came to us from the

kit experts at Mopar. The 440 source. Now they balance all the internal systems so they know it's within their specs. With a crankshaft track, Clevite's main and connecting rod bearings and bolts, as well as the total sealing file, fit MOLLE rings and don't forget about locks. The crankshaft is a new forged 4340 steel platinum series. The connecting rod and main journals are stock size and the counterweights have been profiled or rounded. This crank will handle over a thousand horsepower and has a 4-50 stroke. their rods are made from aircraft grade ford 4340 steel and are lightweight now also in series platinum measuring seven hundred from center of large end to center of small end are now shot blasted and x-rayed heat treated which shows us that they have excellent quality control plus they are sol finished made in USA and machined to very close tolerances these forged pistons are made from 2618 t6 aluminum for superior strength without sacrificing weight they now have a 16 16 3 16 turing groove and the oil returns are not drilled above, the valve reliefs will work the camshaft up to about 700 inches of lift under the pin is a big diameter 990 chevy block now if you look closely you can see the reinforcing ridges in the forging which just adds extra strength to the piston now the skirts are diamond finished with a tolerance of plus or minus minus two and a half ten thousand this is over thirty pistons for a final bore of four three fifty we show how to check tolerances regularly even if you don't see it we check them this is what we have for this bill now if you remember that the minimum vertical oil clearance you need in any performance engine build is 1000 per inch of shaft diameter you can have a little more and we make our main bearings two point seven four nine two so by our standard , we should have at least twenty-seven ten thousand clearance ours measure between 30 and 32 10 000 so they are on the good side our raw mags measure 2,1993 and also have 30-32 10,000 clearance.
Once they are in the green as well, this is a step no one should ever skip, no guesswork in engine building, the engine blocks will need a little facelift after machining. Withstands temperatures up to 500 degrees and is resistant to oil and fluids Color is Chrysler Blue Clevite main bearings are now set and smoothed with a high viscosity mounting lubricant This trick rear main seal is available exclusively from jeff gunther at fast fish auto parts features a unique double lip design to help eliminate leakage it is a single split low friction design make a single cut lube it up and slide it over the crank they also sent us this billet seal retainer to complete the install now we're ready to put this 440 source forged crank in place making sure the rear seal goes down too we always put the arp bolts in after the crank is in so there's no risk of denting an axle the lube caps they are on now and fit well. xt a sledgehammer is used to pound the crank back and forth to align the center thrust bearing the net is torqued to 100 lb-ft using arp ultra torque and thrust is checked we have four thousand which lights green to continue on instead of a factory side seal we are going to use silicone with it instead we can knock the retainer all the way down and tighten the bolts the fun has just begun so stick with us welcome back to part one of our mopar build

big block now with the crankshaft set for good the next order of business is a slip on our new camshaft it is now a hydraulic roller offset cams have custom made for us to take advantage of our extra 72 cubic inches and a best breath induction duration is 252 degrees on intake and 262 degrees on exhaust lobe spacing is 112 degrees the lift at the valve will be 640 mils on the intake side and 672 on the exhaust with our rocker ratio remember to take your time on the install so you don't ruin your new cam bearings with the cam in place assembly Summit Racing's billet steel timing chain is ready to run now the bolts are torqued to 40 lb-ft and a pioneering product cam button will limit end play has a billet steel cam gear and crankshaft gear multi-keyed counterbalance to make cam graduation a breeze the cam installs straight up which means the intake centerline is the same as the lobe gap in this case 112 degrees the pistons are next and the pins are secured with a single spiral lock on each side, we have already placed the rings with the top spaced twenty thousandths apart, the second spaced v twenty two thousand and oil rails gap is eighteen thousand using assembly oil will pre-lube the rings and piston skirts apply assembly lubricant to the bearing and drop the assembly in with a few light taps the rings in the bore will come down to the lowest level the cap can continue and is fitted with the arp 8740 rod bolts with all eight installed they will torque to 60 lb ft f Now that the oil scoop is threaded on it matches our oil pan being put on early.
Summit Racing's Timing Cover can now be fitted in conjunction with the mylodon Wind Pan to seal the bottom end. This myladon 7 quart low profile crankcase fits 64 before, the a b c and e bodies arp fasteners will secure it. We are installing a summit racing sfi approved balancer with our matco installer like all of our engines. It is a high volume unit that is cast, we painted Chrysler Blue to match the block. The first part of this build went from this dirty block that needed some attention to this flashy full short block that any Mopar fan would click their heels twice and make a wish.
I've got a little bit of time left but it's not for the mopar now just so you know part 2 will include a whole new top of the line trick flow package that will allow us to make some serious power plus it's now getting electronic fuel injection we predict this engine will get past the 600 horsepower mark with no problem and issues are what you want to avoid in engine build not only because of the cost but also the time and effort that goes into a quality build now , after the break we're going to take you behind the scenes and show you how mike and i plan all of our engine builds starting with the short block planning an engine build is actually very similar to preparing a gourmet meal the quality of the ingredients will make it a success or a great Junk Disposal Engine Building Candidate always starts with common sense questions and objectives realistic and answers like these number one what is the realistic goal for your project or engine is it for a daily driver is it for a street car and pull or is it a purpose built race engine in our case for example we are planning stage three of the in-house power mouse with a power target of anywhere from 900 to a thousand horsepower so that definitely dictates our number two part choices, how much work you can do yourself rather than rely on someone else and this includes the assembly of the machine work and tooling availability and number three what's the biggest what's your budget it seems like everyone wants to do a thousand horsepower for less than a thousand dollars and we're not saying that's impossible it's just not enough handy those motors are called strong but not for long and we categorize them as

motors with cheap power adders there's a little phrase I like to use ar and it sounds real to everyone who is trying to dogreat power very fast you never have enough time to get it right but you always have enough time to do it again and when it comes to engines that get expensive why not spend the extra money and get it right the first time?
Our plans always start with the foundation building the engine block and that is determined by the power level with our power target of three stage small blocks between 900 and 1000 horsepower a factory block just won't cut it b Because Because they're only good for the mid-500 horse range, now it's true that we've pushed them harder for scientific purposes, but we're always prepared for structural failure. Aftermarket blocks are specifically designed with stronger materials. designed to withstand the stress of high performance applications with the selected block there is still a lot to consider and we will get to that next time and we understand that funds dictate projects so spend your money wisely and plan accordingly and you can have a great running engine that will last if you could remove rust without sanding or scrubbing right now you can with evapo rust it's a rust remover that is biodegradable and eco friendly now it's really great because it does the job for you simply dip your rusty bits in it and let it sit overnight now here's an example here's a before and after on a rusty old intake manifold and i have to say we're impressed with the re Turns out now a gallon will treat up to 300lbs steel so needless to say a little goes a long way, now it can be reused over and over again until it turns black, there and s when you know the fluid is used up it will now run a gallon.

This is your z23 evolution sport one click brake kit and it contains a package of engineered components that can easily handle your high performance riding style the kit has your evolution performance galvanized round slotted bevel and balanced rotors that are made with Real cast technology and can run up to 180 degrees cooler than stock Also included are Z23 Evolution Sport pads made with a carbon ceramic formula that provides better bite without the noise and dust Premium hardware and lubricant are included and you can go to powertop.com to find your application and buy the complete kit with just one click here's one that comes up a lot it's good we get asked on a regular occasion what octane fuel should I use in my engine well there are several variables for that question, the octane r requirements for your engine depend on the compression ratio, the type of parts in the mo tor, such as pistons, as well as the conditions in which the engine will be used.
Now, engine octane numbers are determined in a laboratory using a standardized method involving a single cylinder variable. Compression ratio carbureted engine now the octane scale goes from zero to 120 but typical commercial fuels are in the 80 to 90 octane range so what do the numbers 87 89 91 and 93 you see on the pump mean? The higher the number the slower the fuel burn rate now faster burn rates produce higher cylinder temps and higher cylinder temps are what lead to detonation or knock now here is a knock for your information is the automatic ignition of the air fuel charge after the spark plug has a chance to ignite checking this automatic ignition or knock is one of three different ways that an engine can ignite the air fuel charge without the use from the spark plug the other two are from preignition to diesel nd or engine run but they are all affected by the octane ratings of the engine but for now we are only going to discuss knock when combustion temperature is excessive for the rating engine octane rating of the fuel, it will ignite part of the air fuel charge nanoseconds after the spark plug ignites and ignites When the other portion of the mixture spreads, the two reactions produce a flame front that propagates from two different areas of the chamber and when they collide, they will produce an audible thump or popping noise and the result is a spike in pressure and temperature. in that same cylinder making it even more susceptible to the same backlash on the next compression cycle and if all cylinders are doing this it will lead to catastrophic engine failure such as destroyed pistons and engine bearings.
Knock is not only audible, it's also visual, but you do need to be able to read your spark plugs, which takes some experience, knock will leave telltale signs on a spark plug, such as small black specks on the porcelain to an all-over light gray covering. the part of the plug that sits inside the combustion chamber now both are examples of aluminum vaporized from the top of the piston or the combustion chamber which is an indicator of a higher octane fuel and needs better tuning now we need an octane boost and racing distillate is just not an option we turn to a proven product we know works racing gas is a concentrate that is mixed at the pump to reach a safe octane level on the road up to 105.
Well school's over for today so go make some noise with the kids and keep building toys that's what we'll do see you next time.
