Hi folks.
A friend of mine bought a bigblock recently. We would like to know a little more about the cam. It is from Cam Motion, number: R2732-2842-14
Can anyone please help us? Maybe some one out there know which cam this is or tell us where we can find a Cam Motion website or anything.
Thanks
Bjorn, Sweden.

Bjorn,
I just went through my 1992 Cam Motion cat. but didn't find anything that even remotely matched that number...
Here is the name, address, telephone and FAX number if it does you any good...
Cam Motion, Inc.
2092 Dallas Drive
Baton Rouge Louisiana, 70806, USA
Telephone (225) 926-6110, Used to be (504)...
FAX (225) 923-2101
I think you may be in luck, b/c Yahoo "Yellow Pages" shows them still in business!!!
Hope you find out what cam you have...
Good luck, pdq67

I'd GUESS it's a 273 intake and 284 exhaust with a 114 lobe separation although some cam companies don't use odd numbers in duration measurements. He should probably degree it to be sure.

Almost all of the cams listed in my cat. are single pattern, but if it is advertised duration, then it is around a 222/231 duration at .050" cam.
Now if the sucker is a big cam and they are listing duration at .050", then it is like a 308/316 solid lifter cam!!!
They list too many cams for me to try to zero in on lifts to help more or I would... pdq67

what is the difference in advertised duration and regular? i know duration is measured from seat to seat, so the standard measuring points are at .050 valve lift.

Advertised duration isn't set in stone so can vary all over the place..
The industry has taken to using duration at .050" so that cams can be compared one on one!! This is b/c air flow doesn't really get going until about that.
BUT you still can't make power until the intake valve is closed so that the piston can start compressing the charge!!!
That is why static and dynamic compression ratio calculations rely on seat timing values!!! pdq67

Hi folks.
Thanks for the help pdq, I will try and get in contact with them.
I think the guess for 273 deg dur at 050 is correct. It is a camshaft that supposed to do well with a 14/71 blower, alcohol and Enderle injection.
It would be interesting to find out all the specs though, well the manufacturer should be able to help. Thanks again for your help.

I know of a few serious race engine builders that have custom cams ground by Cam Motion. Chances are you have a pretty good piece.
