i'm running BC 272 cams in my truck, and it seems no matter what i do, the cam gears end up about a half tooth out when i run a straight edge across them. with the straight edge lined up on the outside notches on the cams, and both the inner notches are about an 1/8" raised off the straight edge. move the exhaust cam gear one tooth forward and the inner notches come up under the straight edge.

anyone else ever have to deal with this? how did you resolve it? the truck seems to run well now(mid 12's at 108-110), but i'm starting to wonder if the cams being slightly out of time is why my tune is so wacky. -41% global fuel with stock Evo 8 560cc injectors, and my ignition timing is backed off as far as ECMLink will let me at 3000-4000rpm and i still start seeing knock. am i stuck getting adjustable cam gears to correct the timing, or does someone here have a eureka idea that'll keep me from spending the money?
