ive god a 4 bolt main 355. its got a gm forged crank, powdered metal rods and forged speed pro pistons. its got solid flat tappit cam and 64 cc world products sportsman 2 heads with dual springs with 9.5:1 compression. i should be making between 400 to 500 hp. can i get away with running a supercharger with my bottom end? im going to have a edelbrock victor jr intake, do u know any twin screws that will fit on that type of intake? thanks seth

 

what cam is in it ? If you are makeing 400-500 hp ( ummm not to sure about that ) ...then most definately you will need a new cam . also that intake will not work ...if you are bolting on one of them type of superchargers

 

Your bottom end will hold all day long...

on this article they say they use a Edelbrock Torker II Dominator manifold for the twin screw supercharger. do u need to do any fabrications to the manifold for the supercharger to fit on there? what kind of cam are u suggesting me to use? im using a bracket master 2 cam.

How do you figure 500 hp??? With what you mentioned, you must have some serious heads and pistons, as well as ignition to get those numbers. Can you elaborate a bit on your current combo?

 

i said between 400 to 500. not 500. a guy that i know works at wegner performance in wisconsin said i can make those numbers with alittle work the the heads. i dont have the whole thing put together. can you tell me a good head and cam combo for a charger? thanks seth

 

400 is even optimistic. As a baseline anyway. Your probably gonna end up making around 300, with the combo u mentioned
