I want to degree in my camshaft because I am certain it was installed according to the specs on the cam card(Comp Cams 264). It is my understanding that it should probably be advanced some.

Has anyone degreed a cam with the engine in the car? Will it be possible?

Does anyone have a part number for the offset bushings I will need to use?

Is Mr. Gasket #85 the proper bushings?

I have been reading and have found many articles and videos but have not found any information on the procedure to actually install offset bushings and advance the cam. Does anyone have any suggested reading or videos?

what exactly does "degreeing" a cam mean/entail? should it be done on a stock cam? is it some sort of maintenance? or am i just low on headlight fluid?

On an otherwise stock engine, on the marks is generally close enough for most quality stock cams and timing sets.

Sometimes manufacturing errors are made, and it becomes necessary to "correct" those errors. Errors can be made with the cam grind, and the timing set also. Corrections to the event timing may become necessary to make the engine run as intended.

For performance applications, degreeing the cam is necessary, if only to verify that the cam timing events are occuring for best power in the rpm range intended. Advance and retard can move the power to where it is most advantageous to the application.

I'll see if I have a part number still floating around the shop. There are odd and even sets. I'll verify what I have. Can't remember at the moment! :lol:

Chris you are not low on headlite fluid, as Ceej posted it is to make sure the timing marks are in the right place on the sprockets.
By changing the cam timing a few degrees the engine a little more low end torque or a little more upper RPM ability.

The set of bushings I have is made up of Odd Degree bushings.

My set is from Comp Cams and is part number 4760.

Fopar had an even set, so may be able to provide that part number.

Just hop up on SummitRacing and search on cam degree bushings. :D

This set will work with a cam sprocket that has a locating hole. The hole must be drilled to accept the bushing, and the bushing must be installed in the right position to provide the correct cam advance or retard. a three degree bushing will provide either advance or retard.
If you have a locating "Slot" I don't think this type will work for you. Perhaps there is someone that can make a suggestion about that style of cam gear if such is the case.

Last time I had one of those (and just got another one on my NAP rebuild kit), I lay a stock cam gear over the slotted one and match up the teeth but put the stock hole in another location from the slot...punch and drill hole/relocate "dot" if using that to line up initial installation...check alignment/degree in cam, then drill hole for offset bushing if desired...
