Have a 408 with big cam 3000k stall. When you put it in gear the timing goes to -5 to 15 and it won't run. Idle somewhat ok.
Anyone have a file I can look at that would be a good starting point for a GTO?
What should 408 in cylinder size read? 0.83575?
.373 gear, 3000k stall, fast intake, 60lb injectors, headers,103mm tb heads are cnc'd and flow 340.
I looked in the tune repository, but there only appears to be stock tunes in there anymore.
