Your Cam if it is a ford cam and not a hipo should have a UA on it the part number would be a C3AZ-6250V
Lobe lift intake is .2303 exhaust .2375
Theoretical valve lift intake.368 exhaust.381
Duration intake 266 exhaust 256
Overlap 30
Intake Events
open BTDC 16 lift.004
closed ABDC 70 lift.006
Exhaust Events
open BBDC 52 lift .002
Closed ATDC 24 lift .005
Again that a ford cam 1966 ford 289 with the UA marking if it is a YA marking on cam it will be different

The motor was redone about 8 years ago, don't think it is an original cam.....redoing the motor now and I would love to find the specs on this cam and see if I should upgrade it. The only numbers I can find are 1064R. I am redoing the heads and putting large chevy valves in....any recomendations on a camshaft. I am looking to go fairly aggressive but keep some sort of reliability. The motor is a 289 bored 40 over. thanks

I suppose you could try using a dial indicator or some other means of measuring the lift of the lobes. With enough data points on the intake and exhaust you could probably get a rough idea on the profile as well. I did a couple searches and nothing turned up on the part # you found.

If it were me I would just buy a new cam/lifter set to match the way I am building the motor. That way you are starting fresh and there is no question as to what the specs are. The new cam/lifter sets seem pretty reasonable that that might be the best way to go.

You might want to check out the Edelbrock combo's available. That's what I run in my 289, Edelbrock performer carb, manifold and cam, strictly for street but I get a nice punch out of it and surprise a lot of unsuspecting (street rodders) out their. They swear I'm running a "Hipo"!
Good luck,
Rich

got the specs on the cam, it is a sealed power camshaft. specs are GROSS LIFT OF 458/483, DURATION AT 50 IS 218/230 110 CENTERLINE.....this is all good, but it doesn't mean anything to me. How aggressive is this cam?? Looking for some increased power out of mine 289 and not too sure if this cam will help. The motor is bored 40 over with Keith black pistons and we are putting bigger chevy valves in and roller rockers and running a edlebrock intake and carb. Car is 4 speed with 411 grears. anyways, what do you guys think about the cam????

It's a fairly mild cam. You'd see a significant increase in power with a different grind. If you're going with and Edelbrock Intake I'd suggest the compatible cam. So, if you go with the RPM package then the 7122 and the 2122 with the Plus package. A 4 spd and 4.11's I'd go with the Edlebrock RPM series. Comp Cams also make some great cams as well, and the Weiand Stealth intake is no slouch.
