235 Crankshaft in 261?
Permalink  

Last night I pulled the pan on the 261 and noticed that two numbers were painted on the front counterweight of the crankshaft with a paint pen. The number 20 and the number 235. OK so the 235 must mean that it is a 235 crank? Not sure what the number 20 would mean. Does anyone know what the difference between the 235 and 261 cranks are? Should I be looking for a 261 crank considering I am hoping to get more power out of this motor after rebuild? Thanks...Steve

Looks like they share the same 3.9375 stroke just different bores.

Perhaps you know this but the 261 uses the Corvette Blue Flame cam.
