ls4 block capabilitys im curious what can the ls4 block handle. i have a chance to get a ls4 motor out of a wrecked grand prix for 800 and i want to fully forge it and use the turbo set up and run around 20lbs of boost. also what will the front sub frame handle and the axles? i know i will have to get a built trans. there is just something about making a front wheel drive 4 door car dip into the low 10 high 9 area that intrigues me. a 4 door family car that can eat a zo6. hmmmm

But there is no 4T65E HD that will hold that type of power. So far we have one holding 650 just fine. With one more mod we feel we will move that up to 750 crank horse.
Thats the current limitation.
cheers

None of them make a piston for our cars. Some of them had never even heard of an LS4.
Thats the bad news. The good news is Ross will make you a custom set for about 200 bucks more than a standard set. Not so bad.

Try telling them you need a piston for a 3.78" LS1 bore

The LS4 with a forged bottom end, which you will have to have custom pistons made, will reliably make 800 crank horse.
But there is no 4T65E HD that will hold that type of power. So far we have one holding 650 just fine. With one more mod we feel we will move that up to 750 crank horse.
