I checked my Clymer and California Bill books and even the "55 California Bill book only tells about drilling a '39 Chevy truck flywheel for 8 bolts on a 4 bolt GMC crank. It's time for another Leo Santucci to step up and enlighten us on newer possabalities for our old favorites. There must be newer choices for rods,seals,pistons, valves, rockers,flywheels,etc,etc,etc. Come on guys help us out,Please
