I have a '67 Full size Safari with the base 400 2BBL auto and a 2.41 posi rear end. I have a 4BBL intake and Quadrajet that I want to install. Eventually I will do a cam swap and exhaust upgrade. I also have a 3.42 posi rear end to swap in. My question is what can I expect to gain if I start with the intake and carb first? Will it be too much for the factory U code cam? Just to be clear my goal isn't to make a hot rod out of it. I just want to wake it up a bit.
