degreeing cam

[62goldenrodvan]

Just bought all the right stuff from classic inline,
Cam, lifters, pushrods,dual springs and billet timing set.
My question, What is the recommended center line to degree from with this grind CSC-264-O-B ? this is what is on the end of the cam, and it had no card with it. :
Thanks,
Kevin.

Cam cards are on our website, in the Tech section.

Kevin, if you want to advance the camshaft 4 degrees, 106 intake centerline is what you want. At least for more low end grunt go for 2 degrees advanced which would be 108 degrees intake lobe centerline.
More advance more low end. Bill

Thanks guys,
Bill the only numbers that show up sort of close is 107 with -4 deg @ crank gear whitch is half of the duration 214 from .050 to .050.
And I dont get that cam card that you posted not enough information. I looked at that thing for 16 hours and could not find it good for any numbers.
I messed with it so long, Am I looking at the bull in the eye, Is 107 the magic spot and just didnt see it?
I know its hard to explain how to degree a cam, on line.
Just as hard to explain where Im at with it.
I will talk to classic inline tomorrow also.

There have been a few good articles in some magazines lately on how to degree a cam. The Oct 07 issue of Mustangs & Fords helped me a lot. There was an article also in the Jan 07 issues of Car Craft.

Without "lift at TDC" figures, half duration at TDC would be the easiest way to set the cam straight up. You could then double check by exhaust closing angle.

Kevin, read this link. If the camshaft you purchased has a 110 degree lobe center, & you want it installed 4 degrees advanced, you will have to find the intake lobe center & put the camshaft at 106 degrees after finding the intake lobe center. Read this first.

After you have done this i also check the timing events @ .050 via the cam card. Mike you need to publish the timing events @ .050 just as a check on the camshaft.
Doing this will make sure what you want is what you have. If the timing card @ .050 says intake opens @ 0 with the cam straight up with no advance then with the cam advanced 4 degrees the intake opening should be 4 degrees before top dead center. This is just a double check on all the camshaft events. Clear as mud right. Bill

First Thanks for all the help you guys,

And I must give credit to mike and bill,
Bill you were on the money with the specs and mike refered me to george at CSC and george told me a few things not on the cam cards that answered my questions. They try to keep the cam card simple, not to confuse people with complicated specs.

The results I have are:

With crank gear @ -4* @ .007 (where the lobe starts), 25* btdc. and @.050, 1*atdc. lobe center @ 106*. and @.050, 33*abdc. and 63*abdc @ .007 where the lobe finishes.

And with the crank gear @ -6* @ .007,23* btdc. and @.050,3*atdc. with center line @ 108*. and @.050,34*abdc. and 64*abdc. @.007 where the lobe finshes.

So the specs are read @ .005 to .007 thou start to finsh csc cam cards.
The intake open @22* and the intake closes @62* for this grind.

I got 25* and 63* with max lift @ 106* -4

And 23* and 64* with max lift @ 108* -6

Im building this 200 from all the input on this site and hope its a real screamer.

Thanks again every one,
Kevin.
