Mark,
I'd be just about stunned if your little 327 needed or wanted anything close to 20W50, I don't even run that stuff in the 750HP 396 Super Stock engine. The thickest oil you should ever need or want is probably 10W30. That thing would probably be real happy with 0W20, or 5W30, unless it is a lot looser than I think it is. Thick oil just slows you down, and wears the distributor gear (on the distributor and the cam) among other things. If it makes you feel better, I'd say 10W40 in the summer down there in the heat, in bracket mode would be okay. If you're running 20W50 now, you'll probably find a fair amount of ET in 0W20 or 5W30.
