Hello all, I am in desperate need of information for those of you running a twin turbo setup as I plan on doing this with my 68 Camaro that will be powered by a twin turbo LS1...I was thinking of running ported 6.0L truck heads with ARP Gaskets and Studs from Cartek along with a custom grind cam...If you guys could tell me what heads and cam you are running along with what turbos and what your dyno results have been, I would GREATLY appreciate it!

Thanks in advance!
Ralph

I have a stock ls1 with a mti b1 cam and a incon twinturbo setup. Running 7.5 psi on around 15-17 degrees of timing on 94 octane.

 

406ci SBC
4.155 bore x 3.75 stroke
9.2:1 compresion
AFR 190 23* heads
232/226 .532/.528 hyd roller cam
1 3/4" 304ss headers
PT88 single turbo, HKS GT wastegate, liquid spearco intercooler

I have no idea what it would dyno but on the second pass down the strip at only 5 psi it ran 126mph.

Good luck
