I'm contemplating building a "beater" 457 or 471 short-block for my '68 Bee so I can run it hard without fear of hurting the factory original 383. I had read some things about "connecting rod offset" of .060 towards crank cheek that is machined into BBC rods. Is that ideal for running BBC rods in a BB Mopar or would "centered" rods with BBC journals be better, or does it even matter?



Dont know about the .060 offset built into the chevy rods.

On the Mopars, the offset was built into the Pistons.

As far as I know All aftermarket stuff is centered. Both pistons and rods. You have no choice, unless you pay for custom.

On stock mopar stuff there was a benefit by reversing/flopping the Pistons offset for more power.

And for a race/street engine, No , It doesnt really matter. The Factory offset was to make the engine run smoother.
