I’m starting to make a set of crossover pipes and after looking through lots of books, it seems the small block system had the middle two cylinders crossover to the opposite collector. The collectors as viewed from behind with the numbers indicating the cylinders.
8 2 7 4
5 3 6 1
With either firing order, 13726548 or 15426378. The pulses are equal but do not rotate in a circular motion around the collector. My question is, would it help if you made it rotate
I have searched the forum, but nothing really specific comes up.
