<VV> Junkyard dog questions

We'll assume the engine was running when removed. I'd use it. The mismatched 
crank halves should not matter. Sounds like it was a factory set. Possibly a 
late 1963 engine?

Subject: <VV> Junkyard dog questions

I bought a early spyder engine off of e-bay some time ago, so as to have a 
back-up junkyard dog engine to install
in case I needed to do some work on my current engine. I've got the j/d engine 
all the way apart, and have some
questions. The main bearings dont have any markings on them to tell if they are 
std. or oversize-did factory main
bearings have any markings like that? also, the crankcase is a YR block, but one 
half has the cast in relief for a late
crank, the other half does not. Interestingly enough, all of the parting lines 
at the cam journals appear to line up
perfectly, as though the block was machined as a set, and the oil pan gasket 
surface has machining lines that match.
The crank is a early turbo crank (has the correct number for a early turbo 
crank). The crank main bearings have NO
scratches in them, the pistons have NO scratches on the skirts, the oil filter 
was orange with those kooky little slots
along the bottom that required some sort of spline like tool to remove it, 
intead of a strap wrench. The heads are
early turbo heads, and most (not all) of the rocker arm locknuts are the 
original style. 

I'm wanting to use this block, because the lifter bores appear to be in 
excellent shape (still have most of the machining
lines on them) and the cam journals "look" really nice, but I'm a little spooked 
about the block halves being two different
years. I know that I need to actually measure the relevant clearances first, and 
havent yet, but want to know if any of you have
successfully run a corvair engine that had non-matched block halves.
