possible upgrades

[mobile madness]

Was told to get a set of roller rockers for my 4.0l ohv to help improve mpg and power. I would totally do this except, I can not find any anywhere. Comp cams has one set or roller rockers but not specificaly for the 4.0. Plus they were way outa my budget. Anyone else have any more knowledge on the subject?

Thats a good chunk of change for what I imagine would be very small (if any) gains in power and mpg. As far as I am aware of, there are no roller rockers for the 4.0ohv.

I know. If I spend anything over 300 it'd be on a cam itself or a sus lift.

Gears can give you a good boost in milegae depending on the gears and tire size you have now. Its not real cheap either though. If you haven't done so recently do a full tune up. Plugs, wires, air and fuel filter, PCV etc. Maybe even use a fuel system cleaner. It could give you a bigger gain than you think.

Oh I allready have and have done so much more. Need to get my speedometer re calibrated to see how many miles and mph I'm actually doing. I have 235's instead of stock 215's. I don't think that size is made anymore anyway. I'm getting 15-16 as it is.
