Well, just got the cam in and (was) getting ready to check the piston to valve clearance, but something just didn't look right at the back of the engine. I thought I'm probably just being paranoid, given all the headache this engine has been so far, but to check I slowly turned the crank around a ways until bingo. Dammit!
The rear counterweight is hitting the rear cam cover. It's not a whole lot, but still enough to stop things solid when I'm turning it with a half inch ratchet.
Given that the assembly is already balanced, I don't want to grind any clearance on the counterweight, and there's not a lot to grind off on the cover plate, but I gotta do what I gotta do.
The previous engine was a piece of cake to assemble, was damn durable, and ran like stink. This engine has been a PITA from the start. The only thing that keeps me going on the assembly of this engine is the idea that if it was easy, anybody could do it. I was going to sell the old shortblock (it's only got about 5000 miles on it) to recoup some of my expenses on this engine, but I'm starting to feel a bit sentimental about what a good engine it was.
Well, now that I've vented a bit, it's back to the garage and see what I have to do to the cover to gain some clearance.
Edit: Well, I went over and looked at the rear of the old engine and noticed that it had a very minimal rear counterweight. If I had transplanted the guts out of the old engine (as I initially planned until I thought it wasteful to bore out brand new sleeves to 30 over), the crank would have cleared with an inch or inch and a half clearance. So, I guess I'll give the crank manufacturer a call tomorrow to ask why they designed the crank this way. It would easily clear the old style freeze plug in the cam bore, but not this protruding cap setup.
