RC engineering cam history
« on: January 18, 2013, 06:21:45 PM »
I'm looking for information about cams RC Engineering was using on the big bore cb750s.  Besides the known "RC" cams #240, #295, #315, #327, I believe RC used some Andrews, Kenny Harmon, norris cams, etc.  There were also regrind cams done by several companies I think.

I'm interested in any info on the cams RC used in 750s, but specifically what was available in the first few years for 1000cc RC built motors.

Thanks in advance,

George

That one must get great gas mileage ;D!  It's listed in the RC catalog as the "Top Gas Special"  "No specs will be published on this cam.  Specs will be given only to purchasers."   

The cat is out of the bag now.... 8)


Greggo,

    Nice.  The Kenny Harmon D grind was a welded cam with a fairly mild lift increase right?
