I have a 3600 rpm b&m hole shot torque convertor in.

 

I just got off the phone with jegs and said will did u set the vacume advance on the distributor and well u cant bc its a pro billit msd so there is nothing to set. So the next thing he said is that maybe the vacume coming into the carb needs set, Im not sure how to do that any ideas about that?

 

[X(] well the torque converter might be a little high but should help your problem if anything. as for setting the carb vacuum never heard of that one, the whole thing works on vacuum. your sure you have no manifold vacuum leaks? also i still need to know how the engine acts during this period sputtering and stumbling or just a bog or lack of responsiveness.
