Re: g grind cam info (wantacad)

I have the same issue but mine is a used part. There are various markings
25 CWC F1 ...I was told that the AUtotech cams have a tear drop symbol. If I measure I would need to buy something to measure with. Isn't there an easier way?

In almost all cases, any markings cast into the billet of the cam are NOT useful for identifying the cam, only marks which are stamped or etched on the cams are at all useful. This is because the same raw billets get used to make any number of different grinds. Marks like these are what to look for, in this case, the hand scribed name is the manufacturers grind number and can be cross referenced to find the specs.

Everybody needs something like this in their toolbox, whether they think they do or not. They're only about $20, just buy one, you'll never regret it.

I called Autotech and they said their G Grind cam has the numbers 025 B or 423 stamped on the end. Measuring would be the real guarantee of accuracy but if the numbers are there that would also be a valid check.
