Son's engine specs so far:

Machine shop honed block, installed core plugs, ground crank 10/10, repaired/welded worn thrust surface on crank also.
Stock pistons flipped (even though it's been scientifically proven not to do squat) with new ring gap opened up.
218/218 summit cam bout .480 lift with 1.6 magnum rockers.
Magnum heads home brew porting under way.
Can't decide yet between Edelbrock LD4B dual plane or Holley street dominator single plane. Not sure which one I want to give up. LOL
72 904 with shift kit and tci 3000 stall convertor.
dual 2" exhaust/stock manifolds. Ooooof.

All going into 72 Satellite.
