Charles - The YN designation could indeed mean 1961-63 BUT it could also 
mean 1964, which IS a 164 cu inch motor. Mr. Wynne advises against using 
1964 motors because most of them still have the smaller head gasket 
surface. This is an issue I have always had a problem with, because 
after 44 years of substantial Corvair experience I have never seen more 
blown head gaskets on 1964 motors than 65-69 motors. The same goes for 
barrel distortion.

Further, what happens when you blow a head gasket? On Corvairs it slowly 
starts with a chirp and 5-10,000 miles later it can cause a loss in 
power in ONE cylinder. I don't fly but am about 100% certain that won't 
cause a dead stick landing.

To certain of an engine is 1964 or earlier you need to see the number on 
the crankshaft. Getting the head numbers and other identifying feature 
might make me 98% certain what it is but if you are too paranoid and 
need 100% certainty only the crank number will do. You'd be surprised 
what I've seen over the last 44 years.

Again, i don't fly. but I am AM very experienced with Corvair engines.
