 |
|
Hi Guys
I watched a video with a guy dialing in his cam on his new CB Performance engine,How ever he has an adjustable cam gear
It seems a long process and I can see it's worth the effort
My question is what's the point in dialing in a cam if you have a fixed cam gear .You can't advance or retard the cam. Once the cam is bolted to the gear it's fixed, All you can really do is install.
Am I missing something here or not ??? |

| to make sure the cam is ground correctly is the main one , I do it on all four lobes after getting a Scat cam that had one lobe a lot bigger than the other 3 , (10 degrees at 0.050") |

One of my CB cams measured out to need 2* advance and the other was dead nuts, with the same gear. To get them aligned with the cam cards, anyway.
Gotta get the adjustable gear… |

The point of checking the cam timing, is to check your cam timing.
There are no warning lights in the space shuttle for things the astronauts can't control, its true,
but we aren't in space are we?
If it is too far off there are many ways to do something different. |
