I'm running a 7/4 swap cam does anyone know FOR SURE the order in which the exhaust pipes should be paired. I think it's 1 3 5 7 , 2 6 4 8. Please let me know if this is right or wrong. I already have my headers made from lemons but I will change them if I have too. Thanks for looking.
I can't see any difference for the exhaust unless you were building 180 degree headers, not likely, or 4-2-1 headers. I run the same ones on my dragster, 4 to 1, with the 4/7 as I did with the standard cams.
