@jimbo98z Yes, Bolt ons and a small shot. That was last years setup. He went for a fully built 404? or maybe a 406? Im not good with Chevrolet motors. He made over 540whp on the motor this year and 711whp on spray. Pretty nasty.

@FastisFast Your friend has an LS1 car that makes 550 to the wheels with bolt ons? This I have to see.
-
im still more of a classical motor kinda guy but this motor sounds good
-
supras are overrated man nelson racing engines put a tt 427 in a supra cause the 2jz keep falling apart at 1300 hp
-
With the new Tall deck LSX block, would 8.5L be made without any harm to the block? i know it can achieve 511cu but can you push it to 525?
really thats it? I mean this is a built LSx with boost and only 721 Crank HP? Hell Ive seen stock motor supra/s2000's do over 700whp with just boost... maybe its just me but I was thinking this thing would make over 1000whp. My friend Ray, his Camaro (LS1 has bolt ons and making 550whp)...

This was just the break-in on the engine dyno.
The setup made 1012 rear wheel horsepower on 18 pounds of boost.
