Building A High-Performance Smallblock V8 From Scratch Using Only Catalog Parts -Horsepower S13, E18

[Music] hey did you ever hear that expression there's more than one way to skin a cat i used to hear that all the time growing up in arkansas and i can't tell you if it's true or not because never saw any skinless cats i did see a lot of guys go to the junkyard to start an engine build then there was lots of machining before finishing the job since then i've known guys who traded an engine core for a rematch short block to build it up well nowadays of course if you've got the cash you can also buy a new crate engine with most of the work already done for you then again if you're watching your funds you want to work with new parts and make good power there might be one more way to skin that cat sorry peter we're just joking now let's go build a motor today we're going to put together our performance street small block v8 from scratch all with parts purchased right out of the summit racing catalog and we're sure it's going to be cheaper than a crate engine of course it all starts with the foundation and summit racing now offers a 383 block that's machined to accept a 375 stroker crank it's also got four bolt mains the first 760 bucks we spent went for this block a cast iron oe spec block with four inch diameter bores and one piece rear main seal but first we need to get rid of the rust inhibitor coating they use for storing and shipping then a good coat of wd-40 to prevent it from any new rust with our budget and power goals in mind the tech guys at summit hooked us up with a 383 rotating assembly that includes the crank set of connecting rods aluminum pistons flex plate harmonic balancer piston rings and set of full bearings on top of those clevite bearings we're dropping in this stroker crank from eagle which is cast steel and externally balanced well next to our pistons are 30 over hyper eutectics from seal power that made up to these i-beam connecting rods with floating pins now some of you newcomers may be wondering well what's the difference in floating pins and press fit and which is better well that's actually two questions but here's your answer press fit is pretty much what the name implies you have to use heat to expand the small end of the rod so the pin can go in with a floating pin it installs rather easily and moves freely inside the connecting rod most aftermarket pistons have grooves to accept locks for a floating pin setup there's less friction which is a definite advantage in high performance next we can install our perfect circle rings we picked up from molly clevite after we set the gaps now this is a procedure that can be confusing but it's got to be done and in general it's really not that difficult the first step is to install the ring in the bore with the dot up and square it up to find out the initial size using the feeler gauge now put it into the ring filer making sure the filing direction is toward the inside of the ring take a little material off reinstall it check it and continue until you get it right what's right if it's a street motor you just multiply the bore size by point zero zero four five for the top ring which came up to eighteen thousands you multiply the bore size by point zero zero three five for the second ring fourteen thousands in our case in the oil ring it should be a minimum of 15 thousands the final step take an oil soak stone and just knock the edges off the ring opening to prevent scarring of the cylinder so what if you're building a nitrous or blower motor well we put a ring gap chart up on our website that covers just about every combination well next step is to put some oil in the grooves here install the rings and stagger them to prevent blow-by now when you hear the term blow by that means combustion forcing gases into the crankcase and oil well literally blows out the valve covers here's the correct way to stagger those rings place the oil ring spacer gap between the 90 degree arc labeled a then position the oil ring rail gaps at the spots marked b the lower compression ring gap gets rotated to the c position and the top compression ring gap at the d position if you follow those simple steps for gapping and ring staggering you're going to have a pretty nice little motor one that has good sealed cylinders makes good power and last but not least doesn't have any blow-by now in the meantime we have to take a break and i'm going to go ahead and fill these [Applause] cylinders welcome back to horsepower well it all started with engine parts we ordered from a summit racing catalog including our foundation a 383 block our order also included an eagle rotating assembly and after we prepped the rings we installed the rods with seal power pistons the next item from our high performance wishbook the camshaft now ours is a performance hydraulic roller with a duration of 234 on the intake 238 at the exhaust at 50 000 slip then after installing the double roller timing chain we go bottoms up to install our oil pump and pickup now the pump is a high volume piece and it delivers about 20 percent more oil than a standard one next we have to install our timing cover since we're using a one piece oil pan gasket the cool thing about this gasket from our felpro kit is the compression stops around the bolt holes that prevent over tightening finally we can close up the bottom end with a deep sump 6 quart street strip pan from moroso and bolt up the oil filter adapter now back on top we can drop in the hydraulic lifters and remember here plenty of assembly lube on the rollers and the sides of the lifters we ordered an installation kit that includes dog bones and a steel spider to hold those lifters in place there are lots of ways to cut corners when you're budging an engine build like ours but if you want to make some serious power don't go cheap on your cylinder heads these aluminum performers go for about 570 a piece and for that you get some obvious features like cnc machined 185 cc intake runners for better flow and some smaller premium features like in here bronze valve guides that transfer heat better and resist seizing with 64 cc combustion chambers we expect our combination to yield about 10 to 1 compression ratio oh no pension pennies on head bolts either these are arps with sealant on the threads well time now for the pre-measured push rods from our summit valve train and don't forget to put a dab of assembly lube on the tops to prevent scarring during startup lastly a set of 1.5 ratio aluminum rockers they are stud mounted which is a popular choice in high performance builds for both strength and adjustability with the lock nuts loosely in place we can take out the slack in the push rods and lash the valves the intake manifold we chose for our 383 is one of summit street strip stage threes now it's a high-rise dual plane designed with separated runners to prevent heat soak and it's got a power range from 1500 to 6500 rpm that open area under the plenum also keeps the fuel and air charge cooler to help make more power on top of this powerbond harmonic balancer we're installing a high flow mechanical water pump our pulley set and finally the v-belt with these chrome valve covers bolted in place we're finished out here and ready to transfer the engine to a dyno cart we're feeding our small block with the help of this summit street strip 750 carb that's fitted with a manual choke and mechanical secondary to get started some royal purple break-in formula it's holding 55 pounds just keep going let it circulate for a minute okay and for fire an hei distributor and eight millimeter spiral wound wires she goes we're burning 89 octane pump gas in our 383. it's got good oil pressure and after a 20 minute break-in at 2000 rpm we're gonna dump the breaking oil and get ready for the run we're going at uh 45 first or we'll go 55. we'll go six grand right away huh yep damn you're brave [Music] 460 foot-pounds of torque 400 horsepower yeah we got a little ways to go pretty good especially the torque watch fingers but good enough never after relashing the valves and swapping two carb jets on the right bank to 78s time for run number two 418 466. that's better we're getting somewhere but let's see what one more degree of timing gets us so we're on a little rich i'm gonna go ahead and put another degree in it degree and a half with 465 foot-pounds and over 400 at 25. it's not a bad little piece you know galley got to go for one more this time with 76s in all four corners all right final run on this thing here we go are you sure i hope so all right 443 horsepower 485 foot-pounds of torque i'm happy with that i don't think we could really improve on that unless we put a 150 shot on it there is time to quit this is it all right man that's awesome we started this parts catalog motor build with a claim that we could pull it off and put out less cash than we'd pay for a comparable crate motor which would be a zz 383 in this case did we do it that crate motor loaded with our carb intake distributor and water pump would set you back about 5 800 bucks our complete parts tab from summit was about forty six hundred that's a saving of over twelve hundred dollars pretty nice trade-off for our labor meanwhile this would be a great motor for a hot rod street rod even a daily driver well that may be up to you because see we're gonna give it away soon and we'll keep you posted on how to get your name in the hat stay with us say when you were a kid did you enjoy taking things apart just to see what was inside of them i know i did i used to take apart my toys clocks uh my mom's toaster one time that didn't go over too well well i guess things haven't changed much here i'm taking apart these oil filters and tell you what while the design is basically the same i can see the technology that goes into one as far superior maybe a lot like the synthetic oil that goes through it well now that we got it apart let's see how they put it together for that we have to travel here to a 355 000 square foot facility in southeast illinois well when someone makes a decision to upgrade to a super premium lubricant one of the first questions we get asked is well what filters should i use and it's really that question that prompted us to do the research and bring to market a truly synthetic ultra premium filter to develop an ultra premium filter the element inside has to provide almost perfect particle removal while also allowing maximum flow most filters compromise with a synthetic cellulose blend the royal purple filter is 100 synthetic it's primarily fiberglass with some polyester for structural support on top of that there's screen wire to back up that media that is the best longest lasting media the best longest lasting filter on the market after the filter elements are pleated and cut to length workers insert the center tubes that prevent collapsing metal end caps with high strength adhesive provide positive seals for the filter element assemblies now with both ends of the filter housing complete the units are heated to 400 degrees for curing meanwhile in another part of the plant rolls of mild steel are being used to make the extra thick shells a magnetic conveyor belt carries the shells to a machine that cuts off the rings then they're steam cleaned loaded onto an automatic palletizer and moved on to an assembly area where each one is placed upside down in a fixture and loaded with a spring finally the shelves and filter elements come together with the help of this machine the entire process is a combination of automation and hand work these hands are installing silicone anti-drain back valves that prevent dry starts now riding on pedestals the filters are ready for that trademark color spinning as the machine sprays on the purple powder coating then they're heat treated to 400 degrees and while they're still hot routed to a machine that applies the heavy-duty nitrile rubber base gasket samples from production runs undergo a severe sequence of tests here it's for vibration and shock at six jeeps to make sure they'll stay together in this part of the lab they undergo 150 000 continual startups to check for fatigue royal purple filters weigh 40 more than standard filters thanks in part to a stronger steel backplate here in a test of first string a conventional filter lets go at 260 psi the oil purple filter still intact at 600 psi perhaps the most important trial is the multi-pass test where ultrafine dust is introduced to the oil before it flows through the filter presently right now is running about 99.99 efficient at 25 micron which is virtually a hundred percent it's virtually removing all of the contaminant and the dust that we are challenging it with the royal purple filter is a super premium filter it is at the very peak of all filter options that are available to the consumer today whether your engine powers a hot rod or a daily driver when you spin one of these filters onto it it's going to have the same high quality as the synthetic oil that runs through it [Music] air tools are essential for fast efficient work in your home shop but don't you hate dragging around a compressor with a bunch of tangled hoses well rapidair products has a new economical 100 foot master kit made with you in mind now it comes with this durable lightweight nylon tubing compressor manifold kit and two air outlet kits now it's easy to install the hose is attached to the fittings in a breeze and you can get all types of accessories to customize the master kit to make your system at home neat clean and efficient now the master kit will set you back about 140 bucks not a bad price for air anywhere you can run but you can't hide from it rust that is it's one of your ride's worst enemies renowned industrial technology developed in 1986 to prevent extreme rust and salt mining equipment is available for cars and trucks too it's called counteract and it's a patented electrostatic technology with a module that connects to your battery it sends minute electrical charges through these two couplers that deploy a very slight negative charge to the body surfaces of the vehicle that charge prevents and inhibits rust and corrosion protecting body panels paint even bolt-on accessories made from dissimilar metals basically the counteract system eliminates the tendency of oxygen and iron to result in rust these things are ideal for everything from daily drivers to show cars and they come with a guarantee that's good even if you swap it from one vehicle to another with prices starting at just under 300 bucks well hope you stay dry and rust free until next week we'll see you then
