Hulk,

Aside from the pistons, the remainder of the rotating assembly should be identical for any given year.

Pistons should be the same too. The Short blocks are identical.

Short blocks are identical. Flattop pistons from the factory are great...now if only they wouldn't install heads with half the intake ports blocked off!
