Yeah , I`d buy new pistons to switch 505 stufF into a diff. block if it was a good one ! I`m still hung up on wanting an alum. block, mines a street car and doesn`t get hammered like a drag car, altho I WILL WASTE A MUSTANG OR CAMARO , traffic permitting .

Hellascious pushrod holes ! ?? And ports ---------
