Tom, I have installed one of these carbs on my '65 Pickup with a stock 292 also. It has HEI, headers and an aluminum intake. I am not driving the truck as of yet (still finishing up body work) but I can tell you that after I installed it, it fired right up and idles and accelerates with no problem when it is sitting there. I was very impressed with the first fireup but I am afraid I can't give you any driveability performance on it yet.
