I am ready to install my cam and was wondering the best way to to set it up. I have the gm "hot" cam with .525 lift with 219, 228 duration at .050 with a lobe centerline of 109 degree, 115 degree and seperation of 112. I am running this application with a set of double hump heads casting # 462's with 10.3-1 comp pistons with full roller lifters, timing chain and rocker arms and a holley 650 double pumper with mechanical secondaries. the engine is .030 over. :cool:

I would not put it in anyother way other than the factory intake centerline. Your going to be building quite a bit of cylinder pressure with that compression and head design (not to mention the cam is designed to maximize cyl-pressure). Any thing lower than a 109 will only increase the tendenancy for detonation at low rpm.

Hi 'metalchecker' - it just may be the time to change your sig to 'degreechecker'!
Now is the best time to learn to Degree a Cam! It is not rocket science - but can be as heart breaking if it's not done.
You will need to get;
1.) a good well marked Degree Wheel
2.) a Positive Stop Device
3.) a pointer - adjustable prefered (thruthfully, I use a home-made one that I've had for many moons)
4.) a good Dial Indicating Micrometer, get one with a good adjustable magnetic base stand if possible, makes things easier.
5.) a good technical reference to explain how to degree cams. You can look on-line in the CHP mag site or lots of others to find good posted articles on the procedure. Any parts of it you read through and don't understand you can post the questions on this board and we'll jump in to explain.

Again - this is not a hard procedure, just takes a little time.
The "magic numbers" you will be looking for are "228 duration at .050". It's as simple as after you find true TDC (top dead center) or "0" on the crank, you turn it to 228* ATDC (degrees after top dead center) and check the lift at the number one cam lobe - it should be .050" of lift! If it is you're done - if not you need to reset cam advance/retard until you get that reading at 228 degrees of rotation.
That is all there is to dialing in a cam. And think how impressed you friends will be to know you did it right! graemlins/thumbsup.gif

As I understand it a lot of performance cams are already ground advanced. Check with the cam grinder to be sure before installation.
