Rusty Shackleford

im looking at doing a carb swap and manifold....im wondering whatn the best and easest setup would be weber sidedraft holly....???i would buy it from racing beat.....also i have an all stock engine right now but in future when i do a rebuild im gunna be street porting...and WAY down the road a turbo.....i know that turbo hats are sold for both carbs but i feel side draft would be better so that i can loop the intercooler....??? also in the long run whats cheaper???
