How far can you offset grind a wd45 crankshaft and what stroke would that be?

If you use Buda (230-262) connecting rods, your stroke will be 4.875". They are 7.375" c to c length versus 7.500" for a stock gas rod.

Connecting rod length has nothing to do with stroke. There are only two ways to increase an engines displacement, an over bore with larger diameter pistons, or lengthen the crankshaft throw. |

Maybe the good Dr meant to say offset grind and use the Budda rods.

I have a set of Hercules rods that are 8.000" center to center and use a 1.998" crankpin (same as buds). I also have new bearings for them. Would sell the package if someone wants them.

The connecting rod length plays a pretty big part in compression distance of the pistons you choose you use. That was the point I was trying to make with the Buda rods being 1/8" shorter than OEM rods. I'm quite aware that the conn rod length having absolutely nothing to do with actual crankshaft stroke.
