Default Re: Cam Degreeing/Checking Important

As I've mentioned before, I have learned quite a bit having Ronnie build my engine. I was quite surprised to hear that the Potvin cam, as marked, would have been at 119 degrees v. 110.

Just stabbing a cam in and leaving it at 119 would created a horrible performing engine.

Being meticulous with what he does, Ronnie got it timed to be exactly 110 degree. He plugged and re-drilled the timing gear so it is dead nuts right.

The reason I mention this is I was left wondering how many cams are actually installed without being degreed and then a owner is disappointed and blames the cam.

Sometimes it is a poor cam choice, but I've wondered how many times it was just an incorrectly timed school that performed poorly.
