This is indeed fun, and VERY informative!

I have a 2002 FRP 392 Crate Engine. It dyno'd 436 from the factory with the following specs:

HD "Sportsman" 2-bolt iron block, 3.850" stroke cast steel crankshaft, 9.7:1 hypereutectic pistons with full floating pins and plasma moly-filled steel top rings.

GT-40X "Turbo-Swirl" 64cc heads

Camshaft: Comp Cams hydraulic roller, .566" intake and .576" exhaust lift, 232º intake and 240º exhaust duration at 0.050" lift. Hydraulic tappets. 1.60:1 ratio roller rocker arms and dual valve springs.

Intake Manifold: Edelbrock "Performer RPM"
Carburetor: Holley 750
Air Filter: 14" Edlebrock w/3" Oiled Felt element
-----------------

The carb was upgraded to a JET Performance modified Holly 750 Double Pumper Stage III, and I'm about to replace the heads with AFR 185's. Any idea where I'll be after that? The articles say 75 hp more, but that seems optimistic. ??

Thanks a million!
