The Number is a serial number not part number to the best of my knowledge. I read somewhere that Crane bought them out way back when. Might give them a call to find out.

HaHa, right Duke. Sort of like showing up at a gal's place on a first date and asking for some of that ol' thang before going out to dinner.

There is a Cam Dynamics 10005 (cam only), 100052 (cam and lifters), and a 100052L (cam and free lifters, a special promotion in the mid-90's). All are the same camshaft. This is a Chevrolet 262-400 V8 hydraulic lifter camshaft. Advertised duration is 272 degrees. Duration at .050" is 216 degrees. Lobe lift is .3027", resulting in a gross valve lift of .454" with standard 1.5:1 ratio rocker arms. Lobe separation is 110 degrees. Cam timing at .050" lobe lift is: intake opens 3 degrees BTDC, intake closes 33 degrees ABDC, exhaust opens 43 degrees BBDC, exhaust closes 7 degrees BTDC. The basic power range is 1600-5400 RPM, with a fair idle. Regards, Chase

Maybe the "1" the original poster saw is an "L" that didn't quite get fully stamped, I've run into stuff like that a lot.

Is this a new cam? If it's not a new cam or is a cam that was previously ran in your motor I wouldn't risk using it. New flat tappet cams don't cost nearly as much as you would be risking in wiping lobes and wiping out your motor.

Crane still sells the 10005 grind, also known as the Energizer 272 H10, with the exact same specs. 100052 is a cam/lifter/assembly lube kit.

Summit also has the same grind. Summit branded cams are supplied by Crane. Summit K0052 cam/lifter kit for $133.95

I'm not sure of who does supply the Summit branded camshafts currently. I am sure that it's not Crane. Chase

Chase, they're not telling who does make them, either. I sent a question thru their "Ask A Question" link, and this is the email reply I received.

OOPS! I'll have to correct myself, I see that the Summit K00052 cam/lifter kit is a slightly different grind than the Crane 100052 cam/lifter kit. The specs for the Summit cam are .458" lift, 218* @ .050" lift, 110* LSA.
