I own one, & am planning on using the carb adapter from the small t-pot base to the holley base for a relatively stock 272 that I am using the f-250, since it is of recent rebuild, & is in better shape than the 292.

i assume that the runners are obviously different on the outer portions, as I see that with the naked eye. Will grinding out the slots, and chamfering down the "transitions" help on this manifold the way that they do on the "B"?



Or am i simply making this thing "un-sellable"?
