Terry:

I don't know if you're aware of it or not... but supercharged engines use low compression ratios. My supercharged cars ran 7:1, and my turbocharged car ran 6:1.
If this 5.0 "Highly Modified" engine was designed to be normally aspirated it "could" have a compression ratio in the 11:1 or 12:1 range. It would detonate & destroy itself within minutes if you made any significant boost at full throttle.
