You might like that Crower 60916 cam, I know yours is a 400 but Rich made 500 hp with his 461 with out box E-heads. You might very well be around 425-450 hp. The aluminum heads have so much better flow right out of the box over unported iron head. The best ported iron head on average flow 260 maybe a little more. The aluminum heads flow 270-280 out of the box. Rich also runs I perform a rpm intake and Q’jet.
