Great info on this video. Never let the stud touch the block. If anything, leave it as much relief as possible, especially with an aluminium head. Aluminium, iron and steel expand at different rates. Let the gaskets do the sealing. A stud touching the block can, and most likely will warp the head at high enough temperatures. Five treads of engagement is more than enough for most applications.

Currently building my 408. When it’s complete it’ll only have 823(looking for) or 243(currently have) cylinder heads at first. Nice to see someone put summit parts to use. I was skeptic and used an eagle rotating assembly. Costed more but I couldn’t find reviews on the summit brand assembly. The oil flow tricks were NEEDED! Thanks a lot there!

@mathewshackelford8037 Год назад

you say "only have 823" but 823's flow a ridiculous amount of air in stock form, 315-320 CFM. It's a great head to use. If you can get them ported, they'll move about 370-380 cfm, and still cheaper than the aftermarket options.

@klewis9867 Год назад

@@mathewshackelford8037 I agree but cathedral port heads are better for heavier cars like mine because they make more low end torque. Which is why I wanted to do an aftermarket cathedral setup to improve the top end hp. I’m still on the fence about it though. I may keep the 823 heads and let the turbo work it out for me 🤷🏾‍♂️

I'm no pro engine builder, but wouldn't the valve angle be reduced to straighten airflow and reduce shrouded of the valves? Not to increase valve clearance. However depending on the build you can also gain some clearance from changing the valve angle, it is just opposite of what he demonstrated.

@titanary68 3 года назад

Definitely a cool build. Buy the LS7 out of the Z06 made 505 at the crank and has 19 more cubes. So this build makes sense if you are building from scratch but if you own a car with a LS7, like my current Z28 you are a cam and tune away from making 100hp more than this build without E85. However if you have ever heard a 408 stroker LS in person you’ll know they sound incredible especially with a big cam as they lobe like no other but straight scream in the upper RPM range. Great build all the way around but I’d have ran AFR heads, trick flow’s are great but AFR is much better lol

What cam did you use guy's?

@11YeeP11 3 года назад

OK Im sure what you are saying about the stud is right but I have some questions. 1) How is the stud tightened from a "relaxed state"? I dont see how it is relaxed when you are torquing it down, and the same would really apply to a bolt. You have to tighten both of them a bit before you get up to your torque spec levels. 2) Can anyone expand on the statement that the stretch is only linear on a stud vs rotational on a bolt? That sounds great I just don't see how it could be different.

@johnherdener6801 2 года назад

Relaxed state means the stud is not tightened into the block. Put it in finger tight then back off a hair ( 1/16 to 1/4 turn ) A bolt sees rotation or twisting forces as you torque it because the threads in the block are resisting rotating due to friction. The stud does not rotate only the nut does greatly reducing or eliminating the twisting force. Thus only linear force on the stud vs some amount of rotational force on the bolt. I use ARP studs on all my builds.

@ramonsanchez7748 3 года назад

I would think you would want more turbulent air to mix air and fuel better than going for a laminar flow , in a cylinder head

@TribbleBot 2 года назад

That's more important for a carb or TBI setup. EFI sprays the fuel into the port right before the intake valve.

@93_yn_fox 3 года назад

@wcox4 3 года назад

I really enjoy your videos. Very informative. I do have a couple questions though. 1} Exactly how does a dyno work? I hear the engine bog down and then take off and was wondering. 2} What is the purpose of the windage tray? I never knew there was such a thing. Anyway, keep up the great work.

@nolanlojo103 3 года назад

Dyno's basically attach the gas engine to a second engine (the dyno) and then the second engine/dyno tries to fight the power output of the gas engine and then uses math and computers to give us HP and Trq. Windage trays scrap excess oil from the rotating assembly which reduces overall rotating mass= better engine.

@nolanlojo103 3 года назад

thats why the motor bogs down when the dyno run starts too

@killerdoxen 3 года назад

Simple answer first. A windage tray helps keep the crankshaft from aerating the oil. You think, a crankshaft spinning at say 5000 rpm, there's some pretty good air movement going on which can whip up the oil. Not good to have air in the oil as air is compressable and can let the crank contact the bearings. Oil essentially floats the crankshaft while pressurized. A dyno is essentially a brake that is bolted to the crankshaft. What's happening when an engine is bogging down is that the brake is clamping harder on the crank. You probably noticed that a dyno run is done with the throttle wide open. The brake is why it isn't taking off. Some of these brakes are conventional friction materials, but a lot of them use water for that braking force. On that brake there is a strain measuring device so the harder it's braked, the more strain is created. Works like a weight scale. That strain gauge is about a foot out from the crankshaft centerline. What happens is that the dyno computer is reading that strain gauge which is reading the torque , or twisting force, the engine is producing. The computer then plugs that number into a formula to determine horsepower. If you look at a dyno chart, torque and horspower cross at around 5250 rpm. That's because 5250 is part of the formula. The dyno is calibrated by hanging a calibrated weight on that strain gauge arm. For example a 400lb weight at 1 foot is 400 foot pounds of torque. They can then calibrate the computer to read the same. One of Powernation's videos had a piece on the new dyno they got and how it works and is set up, but I can't recall it at he moment.

@wcox4 3 года назад

@@killerdoxen Thank you very much for the information.

After you install your pistons, check the guage point for how far the piston is coming out of the cylinder on a stroker. If its out of the cylinder past the guage point, STOP. DO NOT STROKE PAST THE GUAGE POINT, especially with a turbo. This is absolutely crucial.

@joshtheking1772 8 месяцев назад

.015 top ring gap with boost?! That’s a little tight. I don’t know why their engines always make a little less than I would expect, not dogging them, just surprised - maybe it’s the dyno. Richard Holdener made 625 hp with a 408 stroker and a 240 cam and very similar heads.

Richard also made 550 with a dead stock LY6 and a cam/springs and proved you can make 700hp with a stock 823 square port. I think they didn't put enough cam in this for the 400inches and the higher comp. With the oil mods and high vol oil pump it'll suck the sump dry at the 1000ft mark anyway lol.

I thought they said .024 top ring

@davereith54 10 месяцев назад

The .015 was the oil scraper ring.

After all of that work, you have managed to roughly equal the 5.2 XS Aluminator crate engine.

@next2talljones 3 года назад

For a quarter of the price of an Aluminator long block. Lmao.

@next2talljones 3 года назад

Whats funny? Is it that a sub-$10k dinosaur LS can outpace most anything on the market with astounding longevity to boot or that FoMoCo wants $22.5k MSRP for the GT350 powerplant with none of the accoutrement to make it run? Maybe it's the ECP for a 52XS is $1,000 more than the heads featured in this video. Who knows. Could have compared so many other blue oval options to this but decided to go the potato route with the Aluminator.

@chrisdaigle5410 3 года назад

@@next2talljones Wait....now that LS is a sub $10k engine? Your "facts" keep changing. Before, you were claiming this LS build was 1/4 the price of the 5.2 XS Aluminator, which can be bought for under $19k as you actually know. The reality is that the engine in the video would cost a whole lot more to have built for MOST people, because they don't have the expertise to build it.

@next2talljones 3 года назад

Pot, meet kettle. Clearly that "expertise required" wouldn't apply when putting that 52XS into anything, right? We've got into straw grasping early. Yes, I did say ~$10k because that's what you'll have into that package after an okay 7875 kit. Still half of the price of the 52XS that is nothing more than a paperweight without several thousand dollars worth of ancillary equipment which will leave you at the same stage of needing to install it into the awaiting vehicle. Good luck with that considering the respective aftermarkets. However none of this invalidates my original statement being very close to true. The fan boy is strong with this one! Never let sensibility get in the way of farfetched brand loyalty.

the hi flow oil pump is great at fillin the heads with oil, you need to improve drain as the catch can needs to b nasa level to capture all the excess oil happening.... nice build tho..
