i am installing a 76 454 in a 66 chevy p/u and am installing the short {68-72} style water pump and pulleys but last minute realized the 76 harmonic balancer is too wide ! and dont think it will go on any further to line up pulley grooves ? can a 69-72 balancer be installed or what ? i dont have one to compare or wondered if it might throw something off on engine balance ? i dont think the long pump and pulleys will fit in this truck especially w/ p/s ? any ideas ? thanks mike
