see i was gonna tear the whole motor down and replace everything on it. new crank, rods, and pistons so it wasnt set up for a truck anymore....that it would make power for speed, not for hauling or towing. and it has PI heads on it already which i was gonna have shaved some, all new valves, and a set of cams. i figured it would be a nasty motor when it was all done??? maybe im wrong haha.
