Id say the only ideas that you need are how much you are willing to spend without it hurting your feelers.
Driveline is local to you (lapeer to ortonville) so obviously you can just take all the stuff to lane and he can fix it up for you. If your saying that you wont ride it much and its just gunna sit
me personally, I would go the cheaper route. Sounds like either way your gunna have to split the cases and have the crank touched up, bored cylinders and pistons and domes.
bore- $100
Pistons- $180
Domes- $55
crank rebuild and weld- 150 is a guess? Your close to 500 there
or spend 800 for the 392 and the cost to have lane nurse your crank back to health
so 500ish or 800+ ish (assuming the guts of the engine are all good to go)
