PROSTOCKTOM said I don't see this as a fair fight. The 440 is going be a lot faster than the 5.9 especially if you deck the 440 block. Pistons are around .156" in the hole on those engines. I've decked .100" off of dozens of them and installed a decent cam. They really come alive when you shave the deck down and get some compression in them. Tom Click to expand...
