While re-building my 454 to a 489 I bought some Dart Pro-1 heads. When I went to put the manifold on I noticed that it did not fit the new heads. Now I am thinking of replacing it with a supercharger. My concern is my compression ratio. I have 10-1. I am thinking it would work OK on pump gas if I used an intercooler with the aluminum heads if I keep the boost down? The cam has 308/314 duration with 575 lift. Will it work? Who makes the best blowers?
