I'm a virgin cam degree'er so be kind.

I'm swapping my heads/cam/intake over to a different block. My local machine shop put my previous setup together years ago.

I wanted to verify the cam was installed correctly, so a few youtubes later I'm an expert right? Cam is a the stump puller on a 114LSA. ICL at 109.

Here is my post on FB for some picture.

My local shop wrote their numbers down on the cam card when they degreed the cam. 150 and 70 = 220 / 110 deg.

I had the heads on and was using a piston stop. I cam up with the same 150 but 73 for my other, thus my number came up to 111.5 deg. Using the intake centerline method taking measurement in the clockwise rotation. The timing chain does have a small amount of slack.

On the cam card the local shop wrote "crank 4deg Ret". That is correct that was how it came off the old motor and went back on the new to me motor.

So 2 questions and this is really bothering me.

1. On the cam card the engine builder also wrote "Cam key 11+ Advanced" What the heck does this mean? How is it relevant to degreeing the cam? Is it maybe referring to an offset key on the cam? I didn't see one, but wasn't looking either. Maybe referring to ground in advance? That would be 109-114 that would 5 deg. IDK.

2.. I'm tempted to tear back into it and change the crank sprocket to strait up and remeasure. IS the +4/-4 on the crank sprocket equal to what I should see at the lifter? Meaning if I was at 111.5 and move to the strait up mark should I be at 107.5? That too much?


I found this in the Archives. Not sure where my 114 LSA falls into this discussion.
