Quote: Heck, Best Machine had trouble selling the 5 pairs of B1 PSO heads they did, I don't see the demand for a 5" block.
Because at the end of the day, those heads STILL bolt on a bore limited, 4.800 bore space block. If that head was cast in a 4.840 to bolt on the Indy or other 4.840 block, THEN you would have something.
