It doesn't seem to have changed it for the worse though as long as its shifted in a way that keeps cruising RPM above 2K or so. I installed that cam 5 years ago before I tracked my MPG as carefully as I do now, but I don't recall seeing any decrease. Even with this short gearing I averaged about 37 MPG last time I went on a road trip with a best tank of 39 MPG, which is pretty much what this car did stock but with much better performance. A couple of the people who installed this cam actually reported slight increases in MPG, but that would obviously depend on how the car is driven.

I have been tempted to reinstall the stock cam temporarily for testing because I am curious if I would still get more MPG at a higher cruising RPM with the stock cam or if that is caused by my Crower cam. I may do that eventually, changing the cam in this engine isn't at all difficult.
