Just started on a resto on a car that has not ran since 1973 .
It has a Crane cam that has the numbers H5360 and F284 . I did a google on it a didn't come up with anything . Any help would be appreciatted .

didnt find it... but from an older crane book, heres what i found: h-232/3360-6 is a hydraulic with 304 adv, 232 at 50 and .504 lift,`h` meaning hydraulic BUT
f-278/4002-8 and f-288/4134-8 are 7800 and 8200 rpm SOLIDS one at 600 lift and the other at 620 lift, so f-284 must be in between.just my reasonning. maybe it doesnt make any sense at all! all cams listed are smallblocks btw. f-278/4002-8 and f-288/4134-6 are also bigblock cams with same specs as the small blocks, using different part numbers. probably same lobes between sb and bb.

Greetings, this is an F-284 mechanical (solid) lifter Crane camshaft from the late 1960's. It's a single pattern camshaft with 284 degrees advertised duration, and 241 degrees duration at .050" tappet lift. Lobe lift is .302", gross valve lift with 1.5:1 rocker arms is .453". Lobe separation is 112.5 degrees. Recommended valve lash at operating temperature is .028" intake, .032" exhaust. This should have a fair idle, with a basic rated RPM range from 2600 to 6000 RPM.
