The SSRE 4400 is a mechanical roller camshaft for a BBC. Recommended valve lash is .026" intake, .030" exhaust at operating temperature. Lobe lift is .490" intake, .4706" exhaust, giving a gross valve lift of .833" intake, .800" exhaust, with the standard 1.7:1 ratio rocker arms. Advertised duration measured at .018" lift is 328 degrees intake, 356 degrees exhaust. Duration at .050" lobe lift is 288 degrees intake, 312 degrees exhaust. Cam timing at .050" is: intake opens 33 degrees BTDC, intake closes 75 degrees ABDC, exhaust opens 97 degrees BBDC, exhaust closes 35 degrees ATDC. Lobe separation is 116 degrees. Regards, Chase

This is based on a .750" diameter roller wheel. Recommended valve lash is .022" on both intake and exhaust, at operating temperature.
