So the engine needs to be sleeved in one hole and bored .60 over in the other holes. You may be asking why would we bother with a block that's already .40 over and has a split cylinder. Well, during Alan's thirst for more 312 parts, he came across a shop with a set of .6o over pistons. The customer decided not to move forward with his project and the pistons were left over. How does 50 bucks sound for a deal?
You're going to have to bore out a block anyways and what are the chances you're going to find a 50 year old block that just needs to be honed and the pistons are ready to go? These blocks are solid so you could take it out at .80 over safely if you can find the pistons. Besides, this engine is going in a cruiser so we won't be tearing up the street with it. Okay... maybe once or twice. The car will be lucky to see 30K miles.
Another rod needed to be located which shouldn't be a problem. Everett will track one down and make sure the weight is fairly close to the other rods so no big grinding is needed on one rod or seven others. The crank looked pretty clean for the most part. There was what appeared to be some excessive side to side clearance on one journal. We'll see how that turns out when it goes out to the crank shop.
The camshaft was sent out along with the tappets to be cleaned up as well. We'll have the cam reground with an RV profile to give the engine a little more pep.
The heads that came off the block were ECZ-C castings which weren't the big valve ECZ-G we want on this puppy. Alan bought a set of heads off of eBay that we would give a go. A beginning to a search that wouldn't end so soon...
