This is an LS-1 out of a 2003 Corvette. It has a drive by wire throttle, LS6 intake - which was stock - and wierd 339K Heads. The block casting number is 12550592.
I think the 339 head castings were GM test castings. I really have no idea of their performance or potential.
No matter. Once I get it in and sorted, I'm just going to start swapping parts anyway to make it go faster.
I'm anticipating 400hp at the wheels with the exhaust and intake system I'm putting on it and the tune RH is setting on the computer.
If it falls short, I've already spoken with my buddies over at Texas Speed and they have a nice little cam that'll get more like 450 or so.
I'm pretty excited. Turbo motor power for less than a standard rebuild with no turbo lag and big low end torque.
I also weighed the motor but forgot to take a picture. It came it at 440 with the a/c compressor, the starter and motor mounts on it. I'll weigh it again once I get it configured to go in the Porsche. I'll try and get it as similar in configuration as possible to the way I measured the Porsche motor.
And, I'll put it back on the scales when done. The aluminum radiator and RH gas tank are fairly lightweight pieces but I don't know how they'll compare to the weight of the stock gas tank. The stock gas tank was pretty heavy, you know.
