I am looking for a good used/usable 4.140 forged crank with 2.20 rod journals for my build.

Or

A real good price on a New one ! (less than Summit $746.95)



Thanks
Jim

Thats only .005 difference at TDC. Could easily be equaled out with the gasket. The minimal compression ratio wouldn't be bad if you ran it as is.
I ran the compression ratio on a typical 514 cid engine the the difference in ratio was 12.43 to a 12.45

PM me with a price ! After I checked it only gave me 1ci I thought it was more, (513 - 514). We are limited to 515ci in Comp Jet.
