Is there any difference between a LS1 engine from Corvette and a Camaro ??
The Camaro "only" got 305 hp, but is it throttled down with the controlbox?

I believe the z28 is rated at 305 and is not an ls1, the ss is rated at 320. These are underrated #s from gm. As far as the difference between the vette and the camaro I think are the heads, cam, and maybe the intake. There should be some other things but I really dont know what they are.Quote:

Here's some great info from Smokemup. It needs to be updated though.

Throttle Body Information:
A 98-99 TB has a brown spring on it and a smaller throttle cam, GM Part# 17113390.
A 2000-2002 TB has a blue spring on it and it has the biggest throttle cam, GM Part# 17113647.
A Truck TB has a orange spring on it and a cam that is close to the 98-99 F-body ones but it's not an exact fit.
In short when looking for swapping throttle bodies from one car to another check the color of the spring.

:)Thanks A LOT :)
The 2002 LS6 came you have listed to, whats the rpm range its good for? I see a lot of people recommend that cam for turbos, as well as the 220/.581 cam.
In 2001 and 2002 all ls1 f-bodys came with the ls6 intake and I'd give anything to have mine back.
I meant to just say LS6 blocks. LOLQuote:
