This is a hydraulic lifter camshaft, having an advertised duration of 288 degrees intake, and 300 degrees exhaust. Cam lobe lift is .300" intake, .310" exhaust. This results in gross valve lift figures of .450" intake, and .465" exhaust, with the standard 1.5:1 ratio rocker arms. The duration at .050" tappet lift is 218 degrees intake, 230 degrees exhaust. Lobe separation is 114 degrees. Cam timing at .050" is: intake opens 0 degrees BTDC, intake closes 38 degrees ABDC, exhaust opens 54 degrees BBDC, exhaust closes 4 degrees ATDC. This grind can still be custom ordered, but on a three-bolt core. Regards, Chase
