- those early mag crankcases are just waiting to fail when you modify the engine in any substantial way
- tuning mechanical fuel injection is a bit of a hassle even when the engine is normally aspirated. With a turbo it would be ugly.
- The cam profiles on the early S motors in particular were pretty hot profiles with lots of overlap. I am thinking that they wouldn't work too well in a turbo motor.

Still, it would be fun, wouldn't it?

yea would be a screamer for a day or so it sounds like. 9.8:1 wow higher than I thought. good times. thanks.
