Well I have a few probs with it. First off it is a 4779, 750cfm, mechanical sec, and electric choke, which someone has jerry rigged to do away with. Here is my first question, I am going to put it on my bbc 496 stroker, with a th400 auto tranny, i have herd that the rule of thumb is to use a carb with vac secondaries with an auto tranny, is this the case or will this one work? Also, is the fact that someone did away with the electric choke affecting my performance any? The problem I was having was that it wasnt opening up all the way with full throttle, and the choke prob. Let me know some tips, this may be a common, easily fixed prob, but am new to the hot rodding scene and am trying to learn as i go.

On a side note, any of yall ever heard of a PBM cam? Thanks again.
