When he first started drag racing,he was using a 261 Chevy,heavily modified stock head,turning 6000 rpm.Tons of money and maybe 290 hp for an all out drag motor that runs only for 13.5 seconds.But he never mentioned crank or rod breakage.He claims a turbo or mechanical supercharger on an engine like a 235/261 makes sense,get good power despite the poor head design.And make the power at lower RPM's,much less stress on the rods and crank.Of course this requires expensive forged pistons,and the easily adapted better GMC oil pump.But mistakes with supercharging can ventilate the block or pistons in a NY minute if the boost is too high causing detonation,but if ya got money to burn on old engines......................
