Not Ranked
I am really surprised no one has commented. Just for the record the old firing order for small blocks was 1-5-4-2-6-3-7-8. Original Tri-Y headsers paired the cylinders in the following order, 1-2, 3-4, 5-7, and 6-8. The question was, if I am using a EFI roller cam, EFI here means it has the newer firing order of 1-3-7-2-6-5-4-8, then what are the cylinder pairings for the headers?
