Related issue...just installed a freshly rebuilt 475 horse 440...motor was run on stand for cam break in...now in car idles and revs nicely...when test driven with a load on it....its seems to be short of fuel.. I put a new stock 440 manual pump ...which was on old engine with single 4 barrel...guessing I need to upgrade to a higher volume pump?...thx
