Stock Eliminator "Cheater" Cam

Trying to find out the cam card specifications for a Cam Dynamics, "Cheater" camshaft for NHRA Stock Eliminator. My power plant is a 1970 Chrysler 340 small block. Please advise. I'd even enjoy having an old cam card spec sheet if available.

Best regards,

Tom

Call Crane Cams.. Get all the numbers stamped on the end of the cam.
They will need these ID numbers

Mic the major and minor diameters of 1 intake and 1 exhaust cam lobe.

The difference is the cam lobe lift.

A good local engine building shop like Oddy's or Jan-Cen, there may have a
"Cam Doctor" cam measurement tool that will measure the cam and generate a cam card with all the valve timing specs.
You'll have to call around.

Class legal "Stock Eliminator" cams are supposed to have "stock" valve lift.
But the duration could be anywhere from 230@.050" to 270@.050"
The LSA is usually tight (102 to 108deg)

"stock" 340 LA mopar cams are like .430" in .450" ex

Some of these stock eliminator cams are custom one off grinds.

If you are not going stock eliminator class drag racing with your car, there are better more powerful cams. If your cam is worn at all don;t bother reusing it.

Not saying this cam is one, but there have been cam lobe profile/valve spring combos that allowed "controlled" valve loft to occur. This is where the lifter would be purposely allowed to loft off the top of the cam lobe, then it would land back on the closing flank. Tricky to get right, needless to say.

That doesn't sound too radical to me. I was expecting it to have more duration. I know that the top Stock Eliminator guys are very hard on valvetrain parts.

I'll let you know. I have a few different grinds in the shop but I don't think any are Cam Dynamics. Most are Lunati. They're for 68-71 not the 72-73 low compression motor.
