first cam degreed

degreed my first cam yesterday.yea thats right,im one of those guys that just stuck em in .cam was supposed to have 4*advance ground in,but with a straight up gear it was retarded 5*.so it took 4*more advance to get it to within one degree of correct.is this a common thing to be that far off? no wonder i've been disappointed with some cams in the past!

I have seen some out as much as 6* either way...

always good to check them in case

as close as I could get mine was 2* off I left it like that.

can be the cam or timing set , unlikely a oem crank . check the open/closing number to the specs if your just doing lobe center

oem crank, intake centerline and in\ex opening and closing points are all within 1*of spec.now.

most often the timing set.a friend of mine bought a summit timing set years ago and it was off so bad i jumped a tooth on the cam gear and backed it up 2*to get it on the sweet spot.i just put a new motorsport ,from Lem ,and it checked out within 1/2 a * with a comp cam.

guess i should have spent 10 more bucks and gotten a frpp piece.oh well,it's straight now.

I had one cam that we had to jump a tooth to get it in time with using all good quality parts. I haven't had a cam yet that didn't need some advancing or retarting to get it in time. It sure is worth the time to check it.

Was it a 3 or 9 keyway crank gear ?
