<VV> corvair newbee-engine rebuild

[Bryan Blackwell]

To a certain extent, the answer is it depends.  I'm going to assume  
that this engine is very nearly stock, so the answer might be a  
little different if not.

I had an Isky 270 in the 140 in the '66.  Idle was pretty good, it  
did rev better.  This engine also had the K&N air filters, so it  
didn't suffer from the high end limits of the stock air filter cross  
over.  Finally, this was a four speed - the 270 is not a good match  
for a PG.

I have heard that they tend to use a little more oil.  I think I'd  
use chrome rings on a general street engine.  The bigger bores will  
give you a couple more horses, and price being equal I'd probably go  
+.060"

If you are using stock logs it doesn't really matter much.  Either a  
cross over on duals or a big single sounds a little nicer than the  
stock duals, IMHO.  Basically, listen to some Corvairs and when you  
hear one you like, buy that.

See my web site below for more details.
