I must state that you do not lose gas mileage with a larger cam. You can
actually improve your gas mileage with a larger cam. With a larger cam, it
takes less throttle to produce the same amount of power. If you keep your
foot out of the accelerator, you will see your gas mileage increase. I can
attest to this. My stock mileage was approximately 18-19mpg. With my first
cam change my mileage went to approximately 19-20mpg. I recently changed my
cam again (larger), but have yet to check my mileage. (I'll have to do this
after I get done playing with it.) He-he-he!!!

I was wanting the 1.7's because your effectively getting a "beefier" cam
with
reduced friction. I know if you were to go with installing a bigger cam that
gas milleage is reduced. I was just wondering if the reduced friction be
enough
to take up the gas milleage for the drop of milleage from the longer
duration.
Installing rockers arent that bad (rebuilt a few engines and I dont beleive
roller rockers would install much different from regular ones), its
easier/cheaper than replacing the cam.
