As to which crank is best is usually determined by what you are trying to accomplish with your engine, high torque, high RPM's, etc.
At some point I may change out and use my steel 427 crank, but for now I am in pursuit of a torque monster, thus the 428.

In the past, I would have thought that using a stock stroke 3.78 crank would be giving up decent torque, but after I had my stock stroke 427 ( 4.250 bore - 429 ci) chassis dyno'd, it still was a torque monster. Peak RWTQ 488 @ 3850 rpm's (about 600 flywheel), and maintains above 450 ftlbs from 3500 - 5000 rpm's (about 560ftlbs at flywheel).
It just shows that you can build decent torque with a stock stroke.
