[Goat-Racer]

James, I never did sit down and post it. It's something I wanted to do and it got away from me. There is really no magic going on, just years worth of sneaking up on the level of aggressiveness. I'm still even pretty conservative on compression, but there is no hint of detonation or pre ignition, so there must be room for a little more.

Here is the quick rundown:

IA2 block, 4.310" x 4.250", Scat forged crank, Carrillo 6.800" rods, CP pistons with full round 32cc dish that starts about .750" from the edge of the piston, and Total Seal AP steel conventional rings .043"-.043"- 3mm with a back cut napier second ring and 12 lbs. drag on oil ring package.

The heads are KRE high ports with 62 cc chambers and 2.200"/1.72" - 5/16" stem valves with T&D 1.6 shaft rockers. The quality of the chamber is why I wanted to run this particular head over anything ales avaialable at the time (late 2005). The pistons are on average about .002" below the deck and I use the Cometic .040" head gaskets.
It's just a combination of a good chamber, and piston shape that uses both quench pads to blow everything inwards at TDC and make for some good turbulance and a good burn.

The engine has a pretty heavily ported Victor intake, a Pro Systems 1100 Dominator, and little 1-7/8" Dougs headers.

Nothing too crazy, and I know I have some opportunities ahead with bigger headers and better oil control.
