Tech Question

Dan Kreiser, Perry Hall, MD, 70's, Chry.,Dodge,Plymouth, 400

Is there a particular 400 ci. block to use when going to a stroker crank to build a 500)ci. pump gas engine? What crank manufacturer builds good stroker cranks?

Thanks Dan

Dan-

There were a few early-'72 blocks that were slightly beefier in the webbing area, but, for all intents and purposes, use any one you find, '72-78.

All the forged 4.150" cranks on the market seem to come out of the same foundry in China. There are several outfits that import, machine, finish, harden, etc., and sell them, some are Eagle Specialty, Scat, and CAT Power. The MP ones come from Scat as far as I know. Callies offers forged cranks with strokes of 4.500" and up! Beyond that, if it's bucks-no-object, there are always billets.
