dyno day for the demon

My current cam is int. .557/exh.551 running duration int 274/exh 299 112 lobe centers. Ran 12.40's with stock eddy heads. Car weighs 3645 calculator puts it at 410 hp at the wheel with stock exhaust manifolds. Your headers are worth a conservative 30 hp

Just wondering about your numbers here.....410hp rwhp w/stock manifolds? = approx 471fwhp@ only 15% loss, 471fwhp@3645lbs = 11.5's@116 with a car that hooks.......My old '71 340 Cuda 3550lbs w/me ran 12.4's all day @108 = 364fwhp.

Perhaps you made a typo and should've put 11.40's ?
