360/440 cast crank manual flywheel

Correct Cudamark. I've had several 70's 440 4-spd trucks and they had forged cranks and the heavy 6 pack rods all the way through 1978. 400 4spds had forged cranks as well. Of course 72 was the last year for a 440 4-spd in a car but 400 4-spd cars with the 130T wheel had forged cranks too.
