There's another thing to consider with a turbocharged engine behind a 
Powerglide:


It's easy to stand on the brake and gas at the same time which allows 
a LOT of boost to build fast, while stalling the converter which not 
only heats the ATF up *Right Now*, it heats up the engine just as 
fast, as in REAL fast.   Sure, it launches the car hard...


But do this on a regular basis and a month later it's gonna be 
blowing blue smoke out the tailpipe, seen it happen more than 
once.   Running a 'Vair engine behind a Powerglide will work out IF 
you're careful.   If you go romping on it "regular" via stalling the 
converter at lights, the engine won't last very long even if it's 
done up with "all the good stuff".   Again, seen it happen.   You'll 
*Have* to be very careful about those stall-starts; it's very rough 
on the engine and the transmission.



...there was a reason the Spyder and turbo Corsas weren't available 
with a Powerglide transmission.   ;)
