OK. So it sounds like this pump, although incorrect for a 440, could be made to work by simply replacing the small block brackets with the big block type, right?
Also, what's the difference between a small and big block pump? Is the big block pump a bit stouter to compensate for the extra weight of a heavier motor?
If that's the case, I may just wait for the correct pump to come along rather that have an inadequate pump get overworked.
