[quote=AndyF]Not a waste of money at all. I run a low deck 512 in my B body car. It has ported Edelbrock heads and HP cast iron manifolds. The trick is getting the right cam ground for the engine. You don't want a lot of overlap with the manifolds.

Can I ask you for a suggestion for a roller cam with cast iron manifolds (lot of overlap)...
My 451 with 3.23 rear end street tires 1967 Charger run 109.26 12.87 with stock Magnum cam and I wish go roller cam with manifolds
Thanks
