The LS engine is frankly hard to beat from a production engine potential.

We just built 3 440ci versions, pump fuel, with 600ft.lbs torque and 610 bhp @ 6000 rpm and they are very tractable. All with production GM heads and intake manifolds.

Those headers have to go lol ... ceramic would do it more justice appearance wise ... but i guess its not the looks that really matter ;) ... nice motor from what i see ... i have a ls2 l92 408 in an 05 silverado ext. cab .... always good to see more people building them

You are right about ceramic coatings. Been too busy to send those pipes away to HPC. Will actually do it soon while we have a break in the LS1 engines going on the dyno.

pmsl ... a true ignorant comment ! name a jap v8 that can reliably make 1000bhp with a £10k budget ?? . let me guess your either a supra or skyline owner .. the amount of idiots who seem to think there`s makes around this figure with a few k spent is truly comical !

mustangmike from the "fix or repair daily" camp...lol- top fuel dragsters use push rod engines- ask Sainty engineering- they cant make 4 valve engines last on Nitro- they only use 3 valve heads and still cant beat the pushrod Hemi's. Ford is the absolute pits car maker ever- always behind the world in every tech advance, so STOP talking up your 4.6... LMAO- you yanks are a weird lot- MPH speedos , but you measure displacemnet in CC's these days- Guess 5.0 sounds "wicked " to rapper kiddies?

My 408is a 1970 400small block 40 over and with the dart heads its right at 520hp at flywheel not bad for only 2000$ the car only weighs 2600lbs 488 gears its real nice and quick

The LS7 is the only LS-based motor to use longer sleeves in its bores, as it is the only one to have a need for them, with its 4" stroke. Everything else is a 3.62" stroke, and shorter sleeves, (or cylinder bores in iron blocks) are used. You can run a 4" crank in a short sleeve block, but you may or may not run into the issues I mentioned earlier.

[madtownmadman]

Don't even bother building a 408 with an LS1 block, unless you have access to free machine work, and 4.030" sleeves on hand. Thats what you would have to do, remove the stock 3.9ish" sleeves, and press in new 4.030" ones. But then the best way to fit a 4" crank in the Gen III/IV block is to use longer than stock sleeves. It keeps the bottom of the piston skirt from coming out of the bottom of the cylinder, @times a problematic issue. In which case, go ahead and use an ls1 block.
