Speaking of grinders- -- - -I just bought a Storm-Vulcan Model 15 crankshaft grinder. I'll be setting it up with a 20" diameter 7/8" wide grinding wheel for changing the stroke on 235 and 261 stovebolt crankshafts, grinding an offset in the center of the connecting rod journals for a NASCAR tool steel connecting rod made by Carrillo. I'll be changing the stroke from 3 15/16" to 4 3/8", a total stroke increase of 7/16". That turns a 235 into a 266 cubic inch engine, and a 261 goes to almost 300. The engines will look totally original from the outside. I'm also working on an idea to turn a 216 into a 266, using full-pressure 235 components. It will also be a "sleeper"- - - -no outward modifications visible!

Balancing a grinding wheel that size is very critical to safety, and also for getting a good finish on the crankshaft journals.
