RE: This is for the Super Cobra Jet only.

The 428 SCJ motors not only used the 'LeMans' rods from the 427MR motor (with a modified head on the cap screws), but also used the heavier 692 or 712 gram pistons, and a much thicker, heavier wrist pin.

The center counterweight on the SCJ crankshafts were done away with, in favor of moving it out to the front of the block, behind the dampener (this was not the smartest idea, as it contributes to crank 'whip' out there ahead of the #1 bearing, whereas the passenger and CJ motors had it nicely supported by the #3 thrust main).

Many Super Stock racers eliminate the 'cookie cutter', and internally balance the motor via Mallory metal in the flywheel and other crankshaft counterweights.
This thread, so far...
