I'm glad I invested in my own machine tools over the span of several years. Now the only "machinist" i can blame for not getting the job done is myself! Now, if I can just figure out how to purchase another 20 years or so of time somewhere! I've got crankshafts, cylinder heads, and connecting rods covered so far. The guy who grinds my camshafts is in his 90s, and he's on chemotherapy! I hope his cam grinding machinery will be for sale eventually! There's a rod bearing for a Perkins 3 cylinder Diesel engine (Federal Mogul 2015CPA) that can be adapted to the stovebolt 216 Babbit connecting rod by boring out the Babbit metal and a little of the rod material, and "standard" diameter is 60 thousands under the stovebolt crankshaft journal size. The other dimensions of that rod are close enough to use in a late model 235 with a little massaging. It requires the big ends of the stovebolt rods to be resized, and the crank ground to fit the ID of the bearing.

On my stroker 235 crankshafts, I'll be using Chevy small block 400 main bearings, and Chrysler 4 cylinder (3845CP) rod bearings. The smaller diameter rod bearings allow me to offset-grind the crankshaft for a 3/8 in longer stroke and LOTS more torque.
