Well... let me interject a bit of reality to this.

30"= of MAP on an 8.5:1 compression engine is NOT  "just loafing along".&nb= sp;

The ROP, the peak internal cylinder pressures are rather high, u= nless the
fuel flow is up at 33 gph or so.

70F LOP,  30" = ; with 8.5:1 and reasonable timing (22d comes to mind) is very
nice in te= rms of the internal cylinder pressures.

Even 31, or 32, or 33" while=20= LOP with 8.5:1 and 22d timing is OK - - but not
ROP unless the mixture is= VERY VERY ROP.

If the engines were 7.5:1 compression ratios,  t= hen you can add about 3" to
the above, but it is not correct to assert th= at these engines are just
"loafing" along at 30" when they have 8.5:1 com= pression ratios.   At least,
if medium to long term durability=20= is an issue.
