'88 IROC 305 TPI Engine Timing Spec
Anyone have the base timing spec for an '88 IROC 305 TPI motor?
I swapped this motor into my '87 el camino and the decal on the original car is long gone.
I need to set the base timing and can not seem to find it online anywhere?

Stock timing is 6*BTD.

I believe all stock throttle bodies are 48mm, for the 3rd gen. And by the way, the timing info is from 3 different repair manuals and memory.
