What's that Bunkie, you want more torque? Well, how does 600 ft/lbs @ 1800 grab ya'? YEAH BABY, with the torque peak at 4000.
SCR 10.0:1, effective SCR 16.1:1 @ 9 lbs.

I tried some wider LSA's, but the motor didn't like them. Works best on 110. This shorter cam goes over the horsepower hump at 6500, but you have to live with that if you're gonna make the torque this combo does. (600+ ft/lbs from 1800 to 6700). This motor will need 1235 CFM @ 6500. Between the chamber, gasket, piston deck height and piston crown, you'll need to come up with 91.6 cc's to make the 10.0:1 SCR.
