spark tabel questions.
And why is it that GM put in up to 46 degrees timing on crusie speeds and map? Is that to keep the MPG down, It sure cant be for preformance?
I look at a Lt1 bins sparktabel to perhaps use on my car, as the engines are very simular. I know about the lt1 heads have reversd cooling that allow them more timing. Bad ide?
thanks for your time..
