Cam Gear Degreeing

I had a motor built and they never degreed the cams/gears. I have BC 280's and BC adj. cam gears. I really don't want to pull the motor to degree them to get the car to idle and motor break in. I know I will need to run it on the dyno to get max performance. I was wondering if anyone knew of an easy way to set them for break in with a descent idle. I was going to buy a degree kit, but the smallest wheel I found was a 9" and don't think it will fit with the motor in the car. Thanks for all input...

You wont be able to degree them in the car. I would just run it as is until you get to the dyno then start messing with the gears. A vast majority of people never degree their cams and don't have problems.

Yes, you can degree your cams in the car. Done it countless times.

Yes, you should degree your cams even though many do not. I had to degree my FP4r's cams to get the motor to start and idle well.

You can download, print, and laminate a small degree wheel to fit over your harmonic balancer. Cut a hole in the center so that you can still fit a 1/2" drive turn the crank.

Use a dial indicator with long arm tip.

I thought you were supposed to just leave them on 0 and leave them exposed so people know you spent money on them. :shrug:

retard the timing to get more peak HP at higher rpm. advance them to get a broader torque curve.
IIRC, double check me.

Interesting. I never knew that. Sorry for the goof.
 

My car won't idle correctly with the cam gears zero'd out. I need to adjust them just to get it to start and idle correctly. Thanks for the help.

Sound like a tune issue. I know of 2 cars with 280s that once they were figured out idled with stock cam gears.

actually as our exhaust and inlet cams can be adjusted individually you'll probably find altering the lobe separation angle (LSA) will give better results than advancing or retarding the cams as a pair.

Do you at least know your min / max on each cam before they smack the pistons??

You don't want to over adjust and bend a valve.

I need to find someone to degree them for me. I live near TurboTrix and a few other known shops. I feel like I'll get ripped off if I let a shop like them do it. Anyone know of a shop or person that can set them to break the motor in until I get to a dyno? /ubbthreads/images/graemlins/banghead.gif
