    Howdy! I just bought a 1967 coupe with a 289 and rebuild 2 barrel holley carb. It is not running right and I want a 4 barrel carburetor anyway. The question now is, what is the best 4 barrel to put on and do I need to change the manifold? And if so, what manifold should I use? Thanks! Jason in...
