Technical Cam Specs

Is there an inexpensive was to find out what cam specs are. Its installed in an engine. I was thinking a degree wheel and dial indicator.

 

Soft test springs would be a plus.

 

Lift could be measured from the rocker, if it's a solid lifter with 0 lash.

 

A dial indicator and degree wheel is all it takes to figure it out when it is in the motor. You can map out the intake and exhaust closing events and find the lobe lift. The only thing you won't be able to figure out is the lobe profile. Make sure you check opening and closing events at .050" lobe lift.

 

That’s the reason I mentioned test springs over normal valve springs. That way hydraulic lifter are less likely to bleed down.

 

Do most cams have a number cast on them that I could see from below (crank area) looking up?

 

Nothing that will ID the cam grind
