I took my block to a speed shop in Huntsville about 70 miles from my house a couple of months ago. At the time it was the only one I knew of. They wanted $40 to tank the block but it was not that dirt so I told them I would clean it myself.
When I got the block to my shop I found metal shaving inside of the block. I asked around and found two Old School machine shop just 40 miles North of me in Tenn. that could hot tank a block.

I took my block to one of them to hot tank clean for $45.

Ed's shop is like going back in time. Two cam grinding machines, head flow tester, Cam Doctor, everything to work on motors, any motor! One cylinder to large tractor motors. He does a lot of work for the local drag racers. I asked him how old he was and he responded 77. He started in a machine shop in 1955. He is old school.

Last week I took him a cam that I pulled from my GT 40 motor which I could not identify with the serial number on the end. He read the cam and printed out a spec sheet for $10. I learned a lot about cams that day.

I would check with shops that do machine work on motors. They will have a way to clean them.
