It has JE pistons right at 14.1:1 compression. It has carrillo rods, stock stroke. The crank is stock but was straightened and balanced. (its been a few years so I don't remember the exact numbers on the cam) The cam has 600thou lift, 106 to 109 degree center, duration of 305 to 310. I can go look at the grind number on the cam to get those numbers exactly. It has 3 2-barrel minkuni's with the competition intake. 6-1 header. The head has been completely gone through and cleaned up, blueprinted, etc. The only thing that could be done to improve this engine would be to switch to a billet crank. It makes in the 300hp range on 112 octane. I've got close to $12K in the engine developement, so I'm trying to get around $10k. I have only ran the engine on one track day several years ago, then I have run it in the garage to keep it fresh. It is an awesome engine and you will not find a better NA setup for SCCA or NASA.
