Think you are asking with the LD4B Intake?

Lift: 430/444

Or the Melling SPD-22

SPD-22 is in good supply available for purchase online.

Yes. Thanks.
That looks like its a 340 replacement cam.
(268/276 is the Chrysler duration and IIRC the 279/289 is .004 at the valve.)

Did you look at the dyno runs from "Mopar Manipulatin" Hot Rod 1969 ?

I think its fair to make inferences from those tests, keeping in mind that's all they would be are inferences.
