I find it funny that you have to use Edelbrock heads and they specify the castings allowed for each engine, also same thing on the Edelbrock "only" intakes. Plus you have to use MSD distributor's, use there Amzoil, etc. Camshaft and lifters HAVE to be Comp Cams (and will be checked).
I understand they get sponsorship money from those companies, at least I would assume so, but "wow"!
