That would put some fear in ya You might try calling Crane and see if those numbers are theirs... or they MIGHT know who Last edited by MR_P_BODY; 01/06/17 08:39 PM.

It's the BluePrinted (computer-smoothed) equivalent of the factory 2899206 hydraulic lifter camshaft that was original equipment in the 275HP 340 cu.in. 4bbl engines. Cam lobe lift is .2861" intake, .2958" exhaust. Gross valve lift with the standard 1.5:1 rockers is .429" intake, .444" exhaust. Lobe separation is 114 degrees. The duration at .050" tappet lift is 210 degrees intake, 221 degrees exhaust. Cam timing at .050" is: intake opens 8 ATDC, intake closes 38 ABDC, exhaust opens 45.5 BBDC, exhaust closes 4.5 BTDC. This particular cam was produced the 4th week of 1987. Regards, Chase
