I'm thinkin the same when I get back from Arkansas I will tear it apart and re check everything. When I didi this it was 4 hours before the pull and a little rushed.
 
I've run several cams

I degreed my cam in and it came in at 109 builder says it should be 99 so I backed it off one tooth and it took it down to 104 truck ran worse. My question is it even possible for the centerline to change 10 degrees by regrinding, the cam was installed straight up per instructions but this cam was originally a 24v cam before regrind. I understand that gear tolerances are different on every truck but 10 degrees I don't think so! If a person was to take a 24v or CR cam and put a 12v grind on it would it be giving me these syptoms. What really confuses me is the truck ran fairly well all year but the last three pulls were on a tight track and it would drop from 4500 to 5000 out of the hole down to 3000 and slowly come back up and then fall on it's face at the end. Thats why I ended up degreeing the thing in. I am working with the mfg. but I just am looking for some other insight.
Thanks

I had one that was -9* when degreed in. It was because I have a 3rd gen and the cam was a 2nd gen. Cam ran fine. I don't know that you have another gen cam in your truck but it is possible. The grinder should have a card on it in file and should be able to tell you.

Did you leave it at -9* and what did the grinder say to set it at.
