degreeing cam: is it necessary?

The guy that is installing my cam asked me if I want him to degree it or not. My question is with a TR227/224 with 114lsa or any other cam for that matter, what is the purpose? Are there any benefits from doing this or is there nothing really to be gained from this? Any input would be appreciated and I really need to know by Friday.

Yes have him degree it, some people just throw them in dot to dot but it's a good practice to degree it to make sure the grind is were the cam card says it is.

Peace of mind mostly... as long as your clearences are OK, there is no absolute need to degree the cam. But since it takes all of 5 minutes to do, why not?

Re: degreeing cam: is it necessary?

Degreeing protects you many ways.
Makes sure the cam is installed as per the manufactuer...and make sure the cam was ground as per your orders.
Makes sure the timing chain installed correctly as per the cam.
etc. etc. etc.

I "ALWAYS" degree them.

It's just good practice.

Re: degreeing cam: is it necessary?

I there a way to accurately degree in the cam WITHOUT the cylinder heads off? I would like to do this but don't want to take the heads off for the job.
Thanks,
Gert

I would recommend ALWAYS degreeing the camshaft. Why rely on the grinder operator to get the index correct? If you are installing a custom ground cam, aftermarket timing chain, aftermarket crank, (ie anything that may impact cam timing) it is plain stupid not to degree it. If you put that kind of $$$ and effort into your engine, do it right <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Plus, performance drops-off in a hurry as you move away from a proper ICL <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
