Thanks - I've already found the list on Clarks website that points me 
in the right direction with all the numbers for heads & blocks etc. I'm 
not planning to get too involved at this stage - I just want to avoid 
obvious pitfalls like finding I've removed a 164 engine & replaced it 
with a 140!
I have done very little to any of my Corvairs except drive them, so I'm 
not familiar with all the quirks & pitfalls etc. I don't plan on getting 
involved with engine rebuilds etc unless I have to. I do know that one 
of the cars seems noticeably slower than the others though.
Talking of fan bearings, somebody on here was designing a rather clever 
fan upgrade - anybody know if that came to anything?
