13.3's to 11.8's to Forget it...

over 40 years ago my 1972 .030 over 340 Duster ran 11.82 while being street driven on pump gas. Stock crank, stock rods, 2.02 heads ported by a young kid that thought he knew everything (me) and a solid lifter cam. Given the choice I would pick a magnum head way before our old junk heads. It’s not that hard guys and way easier today.
