Stop discarding good 340 engines ! !

I've had a hell of a time finding a shop around here that has a sonic tester or that have a honing plate for a SBM. I'm going to try and buy a tester off Amazon to check my three blocks before I take them in for machine work. Might have to make my own honing plate on the mill too. Not a big deal if I can trade it towards some of the machine work because I doubt I'll need it again.
