Default New Third Gen LS1 Swap

Here is my winter project. 1990 Iroc-z waiting for the 6.0L conversion.
I hope to get some good power and times out of the new setup.

6.0l forged shortblock
Comp Cams Xer287 238/240 @50 x 605/609 110 centerline. (might get a different cam)
Ported 241 heads
Victor Jr with 750 Mighty Demon.
Two stage NOS setup.
