Something in the 400-450 should work fine. And you will want to say with a cam lobe seperation of 112-114 kinda like you would as if your running NOS.When i spoke with paxtion 17yrs ago when first thought about doing this I wanted TWO of them One for each carb at the time. Their kits came with a hat for the carb.and what ever else was needed at that time. Or i would have had to make my own if I only wanted one Hat. And if i remember right It also came with all That was needed to be mounted on the Motor?? JUST DOUBLE Check with THEM. AS for The Intake Offey Or Clifford will work just fine.JUST Call who evers cam You plan on going with and Tell them what you want to do and You planon running a blower/superchager/Turbo and They can tell you would be a Good Choice and what will be a Good Base line to start the timing at. Also step up to a Elec. fuel Pump. Hope this Helps.}[oooooo]

PS Think TWICE. PLUMB ONCE saves Money and Headacks.
