Thanks, yes old Super stock motor builder who happen to be a world champion said they did it in the day too, but he also said the Chrysler guys said you didn't need to balance the assembly either back then. I guess not for a few 1/4mi passes.

I have everything to go stock, but crank had crack. Since it was a back fit to a 383 car, with an available 440 crank decided to ask. 440 to a hemi stock sure looks the same, and both are undercut. But adding weight would be a no go I guess.

Got it on the new crank, and I can get one at a reasonable price but I am starting to say no to Chinese regardless of the quality. Which may mean finding an old hemi or use the old 440. Of course no to Chinese may also mean find a new hobby.
