I purchased a L98 TPI motor and 700r4 trans out of a 92 Z28 about a year ago and decided to do my first V6/V8 swap. I decided not to run it as TPI for now so I converted it to TBI. Got everything out and everything in without issues.
I did my initial base timing at 6 degrees because that is what a TPI L98 is set at. The motor runs OK but the more I think about it the more I wonder if that is correct or should I be setting the base timing to 0 as if it is a truck motor. My truck is a 1988 and I swapped the V6 PROM out with my 1988 C1500 V8 PROM. I am running mid length headers and a full dual exhaust.
