Just swapped in a 2871R....no real engine mods, except for 740ccs, greddy divided turbo outlet, greddy rspl front mount, etc.
Made 305 ft-lbs and 318 hp at 17 psi.....tuned pretty conservatively by Jeff Evans in PA.....He said cams should add another 40-50 hp no problem. Power band feels great.
Like codyace has said, flooring in 1st and 2nd is almost useless...even from a dig in 2nd, flooring it results in traction problems, sometime in 3rd too!
