I can not remember if it was here or on the HAMB that someone used longer rods and off the shelf pistons. Also save 1.25 lbs per cylinder. It may have been for a 302 but 270 I think. All GMC rods are te same except some have a bigger pin and there is a difference in the width of the tab that holds the insert on the crank end on some of the newer engines. 8" Hudson rods will work using a Mopar bearing. 270s can go out safely to almost 4" bore and some have gone all the way to 4". My 270 is a '57 and has the newer style small port head. Just fine for the street. Anyway there might be a rod that opens up piston choice.
