Of course...I'm running into problems. Par for the course with my projects.
I ran by my machine shop to drop off the heads to get flat milled to 112cc and have them cleaned up/gone through, and while I was there I grabbed a set of x bearings off the shelf to start setting up my main clearances....I started at the front. All went good except #4...had to do some work on the backside of the shells to get me where I wanted to be, and then the rear main...measured at the back of bearing I had 0.0041...OK...fine. Move forward to measure the front of the bearing and I see .0063"..
Whisky....Tango....Foxtrot?

Threw in a different bearing, same thing. Took the bearings out...same spread front to rear. Started drinking at this point and kicked some stuff around the garage in frustration. After several more beers and trying to figure out what I'm seeing here, I flipped the cap over and inspected it very closely..there's evidence of line honing on the front of the cap, but not so much towards the rear...indicating that maybe, a piece of crap was under the cap when it got line honed the first time a couple years ago, and I only measured the bearing at one spot when I built that motor...so I never noticed it. Well, now that the cap is mating correctly to the block and not tilted, that opened up the front of the cap...Fawk. It's already been align bored once...and the rear cap doesn't fit as tight as it once did, so this block is trash. Dammit...it had a perfect bore to fit the .030 pistons I already have too.
Grab the other motor with the crap bore, and pressure washed it, then threw it on the stand and measured up the mains...they look good. no more than about 0.0002 taper from the front the back of any of the mains. Threw some bearings in there and checked my clearances....all look good with X bearings. Brought that block down to the machine shop yesterday and as luck would have it, he has a set of the pistons I need sitting on the shelf...for the low low price of about $600. It should all be done by Friday and ready for me to assemble this weekend.
It's only money right?
Stupid boat
