PURPLE SHAFT ID

[CFD244]

Hi Folks

Looking to ID a purple shaft cam. From what I understand, they are color coded. This one has some green paint near the oil pump drive. Does anyone have any insights? Thanks.

I have no way to measure it. It is in a brand new engine, and the owner can't remember.

Set up a harbor freight dial indicator setup in the valley so you directly measure lobe lift. Do you know if it’s a solid or hydraulic cam?

I've never heard of color coding.....except for purple. lol As mentioned, get a lift figure and we should be able to make an educated guess.

It's hydraulic. Trying to figure out if I want to buy this fresh 360. I'm looking for mild one and don't want to tear into it.

Paint spots, don't know of that being a accurate way to identify purple shafts but maybe. I would measure the lift and that will greatly reduced the possibilities. if you use that combined with what type of camshaft hyd/solid and should be able to determine the camshaft fairly easily.

You really need one of these setups anyway. The second one should be a link to the cart that has a 0-1 inch indicator and a magnetic base and stand in it.

I've got all the tools. Unfortunately the engine belongs to someone else and I can't get in to measure it. When I inspected the engine, the cam is a brand new purple shaft with a swatch of green paint. Engine has never been fired. I was hoping that was enough to ID it to help me make my buy decision.

measure an open valve rocker to a closed valve rocker with a straight edge and extrapolate the lift.

Extrapolate? You been drinkin and watchin Star Trek again?

Similar to educated guess the high the low based on semi accurate data though some figures are assumed to explore and obtain a realm of conclusion

FWIW, those that have the cam in hand before installation. The camshaft numbers are stamped on the back of the cam. Sometimes the numbers will be stamped a digit off by one. That would indicate it was part of a kit, cam and lifter. But that’s tearing into the engine…. I know….

Run it see if you like it that will be the funnest way to determine it.
