There is a new crane cam and lifters that came with the parts stash I just acquired. There is no cam card in the box. Box is labelled with a sticker that states part number 901151. Nothing comes up in google. Anybody on here have a clue what the specs on this thing are? Don't want to just throw it in an engine without knowing what it is. Found another number F228/3067-8

Surely some of us still have their old Crane Cams catalog. I know I have an old Comps Cams catalog.

Don't know it you frequent hotrodders.com, but they have them.

I found some specs for the second set of numbers. I'm concerned that the lift is too great for stock valve train. Installing this cam will require cutting the valve pockets and installing Chevy springs. Then it dawned on me. This cam was picked out to go into a head that sports the Volvo rockers. Those have a 1.55 ratio not 1.6 Guess I'll just leave this cam with the rest of the new parts that were intended to go with the Olds engine. I'll just order another cam with a more modest .450" lift or so with stock 1.6 rockers.

Todd, If you have calipers or 1-2" micrometer, you can get "very close", on lobe lift. Measure slides/flank and subtract from heel/nose dimension. Volvo rockers are closer to 1.5/1. Your results may vary. Indicator on the spring retainer while cranking the cam from heel through nose, use a light checking spring, and you need only spin the cam, not the recip. assembly. Cheers, roverman.

Cam specs for the Crane F-228/3067-8 should be:

228/238 degrees duration @ 0.050" lift
290/300 degrees seat duration
0.3067"/0.3200" lobe lift
0.475"/0.496" lift with 1.55:1 rocker ratio
0.490"/0.512" lift with 1.60:1 rocker ratio
108 degrees LSA, 104 degrees ICL

Dan LaGrou told me many years ago that the Buick 215 rockers weren't near as advertised, either.

Those aren't bad specs at all.
