Need a reference for turning counterweights down and grinding mains on forged
440 crank to drop into B low deck block. Thanks Moparts!

Ohio Crank....Does right by me...I know its not local, but if needs to be right, they get my vote.

Check with these guys. Cam Grinders Inc. Might be able to help ya. http://www.camgrinders.net/services.html

Call Dave at(253-931-1148) Aluminum Head Welders in Auburn and see if he can or will do that for you, tell him Cab sent you Do you know how much your crank needs cut off of the counter weights to clear? I think 7.25 is the numbers most guys use to clear the low deck blocks main webbing If he can't or won't do it ask him who is really good at doing that locally

I had my RB crank magnafluxed and cut down by Pacific Engine Rebuilders in Tacoma. John Tillits (sp?) is the owner there and the guy I dealt with. They also bored, honed, and decked my block and balanced my whole rotating assembly. The tolerances were dead on when I assembled it, and I was real happy with their work and communication. I don't think they really market themselves as a performance shop, but I found them to be completely capable. I'd go back to them in a heartbeat.

I had an RB crank ground to B/bbc specs at Jobbers Service here in Portland. They have a location in Kent that might have the capabilities you need.

I was referred there by a local machine shop and it seemed to me they specialize in crank work. A lot of shops will take your crank and send it out to a specialist anyways. You may never know who actually did the work.
