That's a lot of changes, it would have been nice to see what the m1 would have done in comparison.
@Rat Bastid will have a 360 on the dyno soon and will be testing an rpm and an m1 back to back so it will be interesting to see the results. Also will be testing 3 different size headers on it as well, 1 5/8 dougs, 1 3/4 hookers and 1 7/8 hookers.
