How to Guide: Degreeing Cams on 6G72 w/ Pictures

[oohnoo]

I could be wrong but I think your missing the fact that the cams themselves could be off, that's why you degree them finding the center of the cab lobes, not "ASSUMING" they are cut correctly. I remember Ray saying that BC cams are junk and that he's never had nothing but trouble tuning with them and removes them from any car he builds. I attached the cam card for mine.

Take a look at the BC Cam Card, the note states set to "0" and then tune from there for best result, well 0 is 109.5 in/106.5 ex for us....BC could have reccomended 1XX in/ex but that wouldn't be zero (0) on our cars...Just to clear up any confusion here is the math from the BC Cam card to show the BC cam "0" is the same as our cars ((180+7+31)/2)=109 CL intake ; ((180+1+33)/2)=107 CL ex...

Hey bob, doesn't really matter how off the cams are..if you degree any cam to our zero..109/106 then you have a reference point inwhich you can adv or retard them to what ever you want..right now your cams are degreed to a recommended 110 intake and exhaust you could easily move them back to zero with a little math...degreeing just gives you a refrence point until you tune for best results..my brother is running these BC 272
after we degreed them and they seem to be kicking ass..
