UPDATE: and not a.good one. I'm not a professional,.but I believe this 340 is toast...
The main and rod journals on the crank have scratches I can get with fingernails. To top it off the rod and.main journals have been cut down
.030 already according to the bearings.
The block has some absolutely bizarre wear in the cylinders. I just don't understand why or how. This motor has literally less than 200 miles on it. It has however been sitting on and off while the car underwent it's "resto" While it was bagged in a garage, maybe moisture got in? Its already bores .040 over.
To be honest, I'm not sure it's worth it to me to bring it .060 over (even if it sonic checked good), buy a new crank, pistons, rods and do all the machine work over. Not sure what I'm going to do and maybe I'm jumping ahead. Gonna bring my dad by this week to get his opinion as I don't think it would clean up with a hone.
Pics of the worst cylinders, they all have some version of the wear. Pics of the bearings and crank.
