a few months back i sent a 4.375 stroke bbc callies crank to shafteck to get welded,reground and re hardened,1100 bucks.still way cheeper than a new one but for a 4 inch stroke gm crank it would not be cost effective to have it done.what shop will re harden a forged crank for 440 bucks?

i dont think i have ever run greater a 0.010 crank in all my race engines..
i ran a super gas camaro back in 80's

i changed my motor from 4.0 stroke 4.25
ron, (dymanic speed) got all my parts scat crank , eagle rods srp pistons.
i dont know auto motive history , but i can tell you dymanic puts out alot race and marine stuff..

Ron at Dynamic did the motor for my street car, I highly recommend them.
