Well today I finished putting it together and started it up. I'd say most things are OK, had an exhaust leak that was pretty bad at the ball flanges, got that fixed. The big issue currently is that when I release the starter, I get this horrible chirp/grinding sound, it seems to be gone once the engine starts. I tried loosening the bolts and pushing the starter over to no avail. Since this is a different spacer than what was on the block before, I'm wondering if its over-meshed into the flywheel and doesn't retract fast enough. The only other thing I could think of is the bendix may have gotten some grinding dust in it that needs to be cleaned out. I'd say otherwise it seems test drive ready.
