To advance or Not

When then you are golden. If the cam card calls for 102 that's where I'd start.

If you go to mgispeedware.com you can input all the data from you cam card and see graphically what your lobes look like.

The process is relatively simple. Find absolute TDC and set the degree wheel to TDC. Drop a lifter onto intake number 1 cylinder and I use a pushrod or something similar to that so you can set the dial indicator up in line with it.

Next, turn the engine over until the dial indicator reads zero. I never turn the engine backwards to degree the cam.

Look at your cam card. It will tell you lobe lift. What ever that number is, take atleast .050 off of it. For example, if the lobe lift is .380 use .350. Any number .050 or greater works.

Now that you are at zero on the base circle, and we have our fictitious number of .350, roll the crank until the indicator reads exactly .350 and read the degree wheel. Keep turning the crank in the correct direction of rotation and watch the dial indicator move to max lift (theoretically it should be .380) and then it will start back down towards zero. When it is at .350 exactly read the degree wheel again. add the two numbers together and divide by two and that is your intake centerline. If it's 102, you are in the tall cotton. If it's not, you need to correct it. 1 or 2 degrees off doesn't bother me, but it should be within a degree. At 102 if it came in at 101 I'd move it back to 103 and leave it there.
