Ok I see that I can get rid of .5 lbs and increase the compression by .3 .
I'm just wondering if that .3 will make that much of a difference. Hope you
can find the SAE paper Paul and thanks to you and John Vitamvas for the

BMEP is basically torque so you will have to makes some calculations to get
HP. Some thing like Torque in foot pounds times RPM divided by 5252 as I recall.

I would figure the torque at the 4000 RPM and 130 HP level and then figure the
percentage
increase from this chart and re-calculate HP from that. It sure don't look like
much at 6000 RPM. This is old data from about 1981 so things could be different now
with different apex seals. It looks like a larger advantage for car RPM & HP levels.
