Without similarly equiped vehicles (except for the cam) and a dyno run, it's hard to tell. But, on this most excellent web page

I went down to Mods--Power Based

and found this:

Bill Harris (Green Amigo on the 4x4Wire board) tried both cams and his analysis was: With the CalMini cam, he could now maintain speed on hills in his 93 Amigo. With the DeltaCam, he could actually accelerate a little up hills.

But remember TANSTAFFLE: Just like the MAF resistor gives you more power, it does so by lying about how much air is going into the engine and dumps more fuel. This causes less efficient running, and wears the engine out prematurely.

I'm sure both are fine, but make the engine work a little harder than the stock. I have the Calmini cam, but would probably go Delta Cam based on GreenAmigo's testimony if I were to repurchase.
