Upon doing some playing around on an engine analyzer, I wanted to show a graph showing the difference in the power production by installing the cam straight up or at 0 degrees.

I would personaly recommend a gear change in the rearend to something like a 3.73/ 4.10 gear to really take advantage of this change.

You can see the torque and power improvement starting from about 2500 all the way to redline and very little power lost below 2000rpm..This is something you will definitely feel at the seat of the pants..We lose more torque than power below 2000 but at 2500 torque and power increase...A great trade off in my opinion...Im not showing actual power numbers as its irrelevant.

The curve is what is most important here.

This example is based on a 97 ranger 2.3L OHC in stock fashion..All Input data is as close to stock parameters as I can make them.

The red and light blue lines represent the cam installed at 0 degrees from the factory 4 degrees of advance.

Its not worth it, you lose economy, and low end torque. If you want power, buy a new cam.
