I heard about a special grind cam the Delta cam is doing for Geo Metros that has been fabled to increase their mileage by 30% I have not called Scott at Delta yet to see if this is BS or? I heard the mystic grind was contrived by a "Lazy B" engineer, and the only draw back was it becomes difficult to pass emissions with this cam. If this is true, I imagine the same could be applied to
a 302/5.0?

I have a V8 Ranger that I would like to experiment with in order to get max mpg.
A lightened & destroked 289 crank/Honda rods. I have a friend that grinds cranks.
Run as much compression that cat pee gas will support.

Run the tire pressure up.
On and On
