Here's the crankcase bore before the big bore work. I measured it to 3.685 inches just for reference to compare to the big bore diameter.
Here's the crankcase with the big bore machine work completed and the stroker wheels and rods installed.
Note the extra oil passages at the base of the cylinders.
The "I" portion of the rod is opposite that of the stock rods. I believe there is more rod clearance between the cylinders, but I should have gotten a before picture.
Note the extra rod clearance to the front of front and rear of the rear.
I measured the new bore to be 3.855 inches.
