Recycled 5.7L Hemi Budget Build Stage 1 - Horsepower S14, E8

[Music] inside that box is our next engine project and it's one like we've never tackled before no it's not a crate engine but it is a running motor and actually it's one that's been a legend now for more than 50 years will you believe we paid less than half of what you'd expect to shell out for a complete 5.7 liter Hemi you see it came from a 2007 Dodge truck with about 50,000 miles on it a perfect engine to recycle for other vehicles we were really surprised to see how well it was pulled and packaged we got the full accessory drive with all the hardware even an engine harness that still hooked up to the factory ECM and if you look real close they didn't even cut you one wire now thanks to being our reckon it looks like we're off to a good start to find the Hemi we wanted we logged onto the parts locator dot-com website clicked onto the parts search box enter the year make and model build in the parts information boxes and a zip code then in less than a minute we had several choices from suppliers on their network including bnr which had the engine we wanted for the price we wanted to pay around $2,000 well it's ready to go into any appropriate car or truck we've got some tweaks of our own in mind to make it an even more powerful and reliable performer of course any time you've got a Hemi for a project you've also got a piece of high-performance heritage it was easily the most familiar four-letter word in high-performance history a history that first ruled the roads in the fifties then the tracks in a growing little sport called stock car racing the 57 Chrysler 300 was touted as the fastest most powerful production car in America thanks to a 392 cubic inch Hemi with twin Carter cars horsepower 375 Plymouth witted for the second generation - paca Hemi and it got no better than the Hemi Cuda with 425 horsepower lurking under that legendary shaker hood a fast-fish that could run quarter miles in 13 seconds Hemis helped mopars win every conceivable type of racing and during the second generation muscle car years Hemis ruled the streets and stripped-down versions like the Super Bee after 1971 there were no more Hemi production cars for over 30 years then came that famous question in 2003 our [Music] plan is to first tear down the hippy motor check all the components and we're not using the factory harness so it's the first thing to go no reservations about getting this Hemi from a wrecking yard you see bnr documents a run test for pressure check and fluid tests on every engine they sell here's something that makes teardown and assembly a little easier the factory put an eye on the intake rocker of these Hemis so you knew which side one on the intake and the exhaust side is left on Marge since we already use in all of the valvetrain be sure to keep it in order we're leaving the heads assembled and they're off to a new piece of shop equipment it's an ultrasonic cleaning system from safety clean that uses high-frequency sound waves and the special solution to thoroughly clean the parts it penetrates to remove even embedded particles inside and outside of each component when the cleaning cycle is finished the optional skimmer uses a metal band to pull the contaminants out of the tank and into an outside container it's worth it to find a machine shop that uses one and we'll be using ours a lot in days to come while the heads are cleaning we can remove the oil pan then spend the engine over and remove the oil pickup here's something unique to the Hemi engine a part that doubles as a windage tray and oil pan gasket pretty cool huh but I'm easily impressed let's spend this thing over and get to the lifters but I given the crankshaft a few spins the lifters get pushed into their pockets for easier removal well at least that's the idea well next using a drill bit to take tension off the timing chain makes removing the chain a lot easier then after removing this cam plate we can carefully pull out the camshaft all right before we tear down the bottom end I want to mark each piston and rod so I know what hole it came out of and the direction it was in there now in case you don't have a manual quick access to the internet or simply don't know there's an easy way to tell which cylinders number one look at the front of the block in the piston that's closest to the front is number one so we have one three five seven on the driver's side two four six eight on the passenger side I'm going to go ahead and mark number one with a punch well here's a good way to check the overall condition of our recycled engine by checking the rod bearings and glad to say that these look almost new compared to this one we pulled out the trash with discoloration which is a sign of heat and excessive mileage also this is a good sign that the oiling system was doing its job as well the cranks next and I'm using this matte co2 low hold the flywheel so we can break the bolts loose then after removing it we can unbolt the aluminum housing that retains the rear main seal it's always a good idea to remove the crank sensor to keep from damaging it then off with the main bearings which also confirms we got a good engine the teardown is done but the best is yet to come we'll be right back [Music] okay breaks over and so is our cleaning cycle in the new ultrasonic machine here's what the heads look like after 20 minutes pretty impressive all the embedded grime has gone inside and out and that's where we get them dry well they'll be ready to go right back on here's a little Hemi heads up for you the way you can tell a 5.7 head from a 6.1 is the shape of the exhaust port on the 5.7 like ours its square on 6.1 it's D shaped now here's the trademark of any Hemi head of course the hemispherical combustion chamber with larger valves and two spark plugs for cylinder now these later versions have a squish area on each side and well not because of that some purists will argue that these aren't real Hemi heads i say they should get a real life you like the heads the crank and other parts cleaned up just as well now we didn't drop the block in because it was in pretty good shape I just washed it by hand in the sink now here's some block facts you need to know especially if you plan on buying one of these as a Rheem and all late-model Hemi 's come equipped with bosses for MDS in the top of the block now MDS is the multi displacement system that shuts off four cylinders under light cruise loads to conserve fuel ours isn't equipped with it so these little white plugs have a rings to fill the holes now on the driver's side this is a truck block so all the bosses are drilled intact if this block woulda came off of the car line some of these would be solid and you'd have a hard time fitting it in a truck so watch out for that with new sealed power bearings in place time for the crank all third gen Hemi cranks are internally balanced with a 3.5 eight inch stroke and I'll use these thrust washers installed with the grooves facing towards the crankshaft only cast-iron cranks are used in the five seven and only forged steel crankshaft and several codes the top rim that helps reduce friction and noise and their press fitted to the forged OAM rods that have cracked caps because of the aggressive valve action and a Hemi engine the cast-iron camshaft is milled on the heavy side to resist deflection with number one at TDC we're ready for the timing set now the chain has a blue link at the top that lines up with the camp sprocket and two blue links on the bottom that lines up with the crank socket and the dot once that's all lined up we're ready to install it next the oil pump can go back in place followed by the pickup fitted with the new o-ring in addition new bearings we're also replacing all the gaskets to keep everything sealed up we got it from fel-pro including this one for the timing cover and we also replace the front seal with some oil on the back of the crank we're ready to install the rear main seal now this plastic disc is there to keep the inside seal lip from pushing out when it goes on to the crank slip that over it this goes right into place since we're reusing the stock camshaft we're going to go ahead and reuse the lifters as well now as long as they go back into the original locations they'll have the same wear pattern and you won't have a problem we're using fel-pro head gaskets on our five-seven Hemi and they made these things idiot-proof on the top of the gasket they have a marking for top right hand side and even the cylinder numbers engraved in it with the heads made it to the deck we're ready for the new head bolts now since there are torque to yield they cannot be reused the factory torque specs are as follows the first sequence is 25 foot-pounds the second is 40 foot-pounds the third is an additional 90 degrees and you do that with a torque angle meter next up are the push rods followed by the factory rocker shafts back up front we can install the last reuse part which is the damper well at least that was the plan you have to roll with the punches sometimes when you hit a snag in your build up now we want to run this electric mazur water pump and their adapter plate but I ran into a little problem this is a truck timing cover and the plate doesn't fit it this is built specifically for a car cover oops so we use parts locator comm again got the right one chip so we don't have to sacrifice the electric pump the car cover has an extra water port that we have to tap and plug it with a 3/8 pipe plug now we can reinstall a balancer and bolts up the backing plate for our ms ear pop it's anodized black with a captured gasket to provide the best possible seal this Mazur 300 series is the Big Daddy of water pumps with a flow capacity of 55 gallons per minute it's also got a built in o-ring so we'll never have a leak from we're going to streamline the Hemis induction system with an EFI throttle body setup we've been wanting to try but had to have a compatible intake manifold like this mod man we got from indy cylinder heads now the bottom runner is free drilled to accept four different top plates including this single four that we're gonna be using there's also a double four and even for a six pack plus you gotta have it a supercharger all the top plates are machined with tapered air shear exits to promote fuel atomization so far no big surprises building this recycled new aged Hemi we'll see what happens in the dyno though when we come back so better stay close we're back and moving on time to see what this thing makes here's a heads up for you guys that plan on putting together a Hemi just like this one the guys at Indy thought a step ahead and put ports in the front and backside of the intake now that's actually a spot for the engine to breathe since the valve covers don't have a location for a breather or even a spot to fill the engine with oil you'll have to remove the valve cover but it's no big deal because of the captured gasket makes things pretty easy wooden pillar up of course you want to be careful not to get any oil in those spark plug holes now a piece of vacuum hose comes in handy for installing the spark plugs all 16 of them because if you just dropped them in you might mess up the gaps next we can bolt up the valve covers and reinstall the stock sensors but that's about time to show you how we're gonna feed that big elephant motor with our mod man intake we've got the usual choices but we've been looking for a good reason to try out one of these fast self tuning EFI systems now you don't need a laptop or tuning experience to use this technology it's a complete system with 4150 throttle body appropriate injectors sensors broadband Oh two sensor and of course the self tuning ECU it also comes with a handheld display unit now that we have the fuel delivery covered with the new fast system the next question is how are you going to get power to the coils and the rest of the sensors well the answer is in this Hemi six timing an RPM controller from MSD now it comes with this box and the nice harness with all factory style connections to plug into each of the components the only thing the fast system needs to see from it is a tach output the connectors are even labelled to make the hook-up idiot-proof for a solid connection make sure you solder the wires for both attack and the 12-volt power source which of course is our dyno battery the last thing took the MSD box up to the harness it's real critical that you wire any efi harness directly through the battery so you don't get interference from outside sources all right now it's time to use the handheld display and this is where we put all the parameters of the engine into the ECU so it can tune itself while you drive or in our case run it on the dyno now once again you don't need a computer engineering degree to work this thing at least they tell me well first we need to power it up and select yes to start a new tune now enter the cubic inches 345 for this Hemi desired idle speed let's go with 800 we're using a single throttle body so we select that 43 psi is the recommended fuel pressure and eight cylinders is correct of course now the ECU needs to know what voltage corresponds to open and close straddle first it captures the idle or close position value then it tells us to hold the throttle wide open until it captures that value and that's it for the basic setup the next step is to start the engine let it warm up oh you can also use the handheld to monitor live data like engine temperature air fuel mix and so on alright we're going to do a sweep from 25 to 6,000 375 horsepower 372 foot-pounds of torque make another run [Music] right nice sweater still has a little bit of a learning curve you go through and it's obviously going through it right now numbers are getting better and better oh wow 400 horsepower at 6,000 rpm with 393 foot-pounds at 4600 smarter rate 3 45-minute old Dodge Ram it's not too bad here's the cool feature should you lose a sensor like well air temp sensor throttle position sensor even an injector the ECU goes into a limp mode it keeps the motor running and you've got enough power to make it home that ought to be some comfort you carb guys we'll be right back you're watching horsepower for a DVD copy of this episode just go to power block tv.com and order your copy for just 595 plus shipping and handling start your own horse power collection delivered right to your door from the power block [Music] for a lot of guys replacing an older muscle car steering column only means one option and that's a pricey shiny new aftermarket piece well now you can recycle keep the retro look and even reap the savings that's thanks to steering columns galore who has over 3,000 columns in stock that are all outfitted with new components and go through a ten point inspection to ensure that you get a column that's better than new now they even give you the option to paint it whatever color you want to match your car's interior prices start at 325 with a core you know this could be one of the handiest tools that you keep in your home shop or take to the drag strip it's called the hotrod calc for mr. gasket it's a street strip performance calculator and the first one with built in solutions for engine building and performance in your garage you can instantly calculate how changes in components will affect your engines compression displacement air fuel efficiency and so on at the strip you can quickly calculate how temperature elevation and humidity will affect your et's here's how you do a basic ET calculation let's say we got out 400 horsepower car that way is 3,500 pounds the et at a quarter mile would be about twelve seconds of course you can factor in more variables for more advanced calculations but the information in here is just about endless not the price however only about 80 bucks well according to my calculations it's about time for us to go but we'll see you next time
