Crankshaft Specialists was an excellent shop and we had a few cranks worked on there with great results. Finding a competent crankshaft grinder who can even get the correct diameters on the journals is nearly impossible now. The 2 shops I used the last 30+ years are closed, and the experts retired. I do not have a crankshaft grinder available nor the skills to operate it. It's one of the few things I have so farm out. In the entire State of OH, there is only 1 reputable source. That is Shaft Tech in Northern, OH. About a 3 hour drive but you do what you have to do. The only other shop I know is really good is Mile High Crankshaft, in Denver. Dave is just fantastic. The work is 110%. But $300.00 shipping round trip from OH. So for basic re-grind for a street engine, awfully expensive. Proper crankshaft grinding by a skilled professional is a lost art. Right now I have a cast crankshaft for a student's 400 Pontiac at a local shop. They tried 3 times to just do a simple re-grind on it. They finally ruined it and it is a throw away. He has crankshaft #2 now. Simply want the crank ground to a specific dimension for proper bearing oil clearance, straight and round. Seems to be beyond their capability. Fingers crossed.

I have a 455 crank reground by CS, in Memphis, done in 1988, everything was dead nuts on when I measured it. the finishes were as close to perfect as you'd ever want them to be. At that time I sent it by Greyhound, and it still was fairly expensive, but worth what I spent when I got the finished product, and everything was correct. I didn't have to swap bearings etc. to get the clearances right, standard .020 rods, and .010 mains fit perfectly. What a shame that they're still not in business.

I still have the engine assembled in my garage, and I'm goin to pull the pan, and check the bottom end before I put it into my next street car. When I built it in 1988 it was a standard bore with low miles, so it still has cast OEM pistons, and stock rods in it. Basically a stock bottom end with that really nice crank in it, and ported 5C heads, mild camshaft.

Mike, I have ONE guy I trust to grind my cranks. I’ve known him for over twenty years. He does grind the rods and mains on spec and the throws are always on stroke. PM me if you need his phone number. His shop is about 35 miles from my house.
