The 199-207-110LSA was designed for competition engines that want to make power at higher rpm but not give up power in the lower rpm ranges. It will really help take advantage of heads that have been ported that flow much better at higher lifts. The duration at .250" and higher is amazingly different than OEM or our other cams.

Below is a guide to help you decide if the 199-207-110LSA will fit in your engine. The following measurements were made with a stock cam in a stock engine and a 188-194-109 in the same stock engine. For reference the 199-207-110LSA has .016" more intake lift and .014" more exhaust lift at the valve at TDC with a stock rocker than does the 188-194-109. Use this when you are plugging in your valve face depth and piston protrusion to help you.
