That is an extreme velocities hat and its the best. DONT DONT DONT use the ATI carb hat!!! Its a piece of crap and so is the Vortech hat and the K&N hat. That polished EV hat is $200 and it works like a charm. All other hats can give you tuning issues because they dont correct the flow going into the engine. As for the carburetor, you need to get it specially prepped for blowthrough supercharging. This usually includes milling the choke tower, installing nitrophyl floats, sealing the shafts, and drilling out the emulsion tubes and stuff. TPCracing can do everything for you for under $500. Dont get a carb box either because they cost $600 and they are heavy. You are correct about the kit only needed slight changes, but actually if you just turn the carb hat to the approx location of where the throttle body would be if you had fuel injection, then the plumbing bolts right up. For my kit I just bought my friends EFI Procharger kit and I tried all the plumbing out and it lined right up. Later I bought Prochargers intercooler kit for blowthrough setups and it all lined up of course but I know it doesnt require anything special. Buy the $200 carb hat and get your carb worked for $450 and your all done.
thaks for your help.
