One of the really interesting things about buying my crankshaft grinder was where I got it- - - -King's crankshafts in Denver North Carolina. King's is a 2-generation family business, one that's been whittling billet crankshafts out of chunks of solid steel for close to 50 years. They start with a round chunk of steel over a foot in diameter, program a CNC mill to the right specifications, and end up with a custom crankshaft for a NASCAR engine, a tractor puller, or even an experimental airplane engine! Of course, years ago, all this stuff was done with a lathe and a hand-cranked milling machine, and then a manual crankshaft grinder! I bought one of their "retired" machines.

I brought up the subject of drilling oil holes in a spray-oiler crankshaft, and the owner of the business says it's something he could do, as they drill oil passages in the billet shafts they make. The first one would be a little expensive, as he would have to do all the CNC programming to make the holes come out in the right places, but others would cost considerably less once the machine knows what to do. If a few people wanted to chip in and split the costs, it might be worth considering, assuming there's enough interest to make it worth the gentleman's time to do the programming. He's definitely one of the good guys in the custom crankshaft business.

I read about guys doing this years ago (maybe it was McGurk) but I think it was on a one-off basis and I don't remember what motive made it worthwhile. I'd be interested to know the rationale. Racing rules? Vintage racing?

It was done along with machining the connecting rods for insert bearings to provide full pressure lubrication to the rods and eliminating the dippers, troughs, and spray-oiling system. The spray holes in the rod caps are plugged and the dippers are removed. Fitting the Melling M-45 oil pump for the 235 and reworking the oil pickup plumbing a little would also be a good idea to increase oil volume. I'm working on the details of putting an increased-stroke 235 crankshaft in a 216 block, along with several other modifications to create a 266 cubic inch inline six with full pressure oiling that looks exactly like a 216 from the outside.

crower cams, crankshaft division already has the program, they did it on my crankshaft, mostly because the programmer didn't have anything to do. however they centered the rear main bearing hole, mostly because I didn't tell them otherwise, but that would be an easy fix. They only charged me like $150

I'm out of practice, but I could still program that in about 1 hour. The setup would take longer than programming it.
