Which supercharger????Procharger or Vortech

[corys69ss]

I am in the market for a supercharger for a 502 with aluminum heads. The cam is 211/230 & 510/540 full roller. I can change the cam no problem for one better suited for this aplication (if needed). Comp. is around 8.75. I do not want to run a cooler right now or at all if I can help it. Hood clearance is also a concearn. 69 Camaro stock cowl. I like the idea of the blow thru Vortech, but alot of guys seem to like Procharger better. The car will have ps also. I think there is some modification to get that to work. What size headers?? Thanks in advice guys. Cory
also would a 118cc chamber aluminum head be better than 110?
