I'm in northern NY. I do have experience from rebuilding a few subaru engines, and I can clean/check, but this stuff is far too rusty to be useful without machining. I suppose the best thing to do is bring it to a shop and ask them what it's worth?
Everything's torn down and all that's left is the crank, block, and heads. How easy would it be to find the right rods and pistons for a proper rebuild?
