blow through carb???

[jasonsnova]

ok now i'm thinking about going with a blow through carb set up on my 71 nova, i was going to do a efi set up on it but am now thinking blowthrough instead...anyway i'm looking at a entry leval system,maybe 8 psi, like vortech makes one that is supposed to fit my car, but alot of people on here seem to be all about procharger?? are the vortechs not good or have problems? problem is not alot of info on prochargers even on thier website....are all procharger setups custom built to order or something? i cant even find priceing...i would perfur a complete kit that comes with most everything , also wheres the best place to shop for one (both price and service) thanks~
