Drock, that's a completely irrational number to hope to average in an Eagle unless you've done major modifications, so don't be discouraged. It could probably be done with an MPFI 4.0, NSG370 6 spd manual, 2.72-3.08 gears, economy stock size tires, and a weight reduction, all while driving in 2wd. Otherwise, an automatic simply will not manage that on average. 25 is probably the max you'll get with an auto, so long as you have the correct gearing. 20-22 would be lucky in your wagon the way it is, but 15-20 is more common. Cold temps and other issues will affect mileage, as well as a faulty ignition or a carb needing adjustment. If you want to upgrade your ignition, the Motorcraft Ignition Upgrade is simple and rather inexpensive.

Makes me feel promising about Kammy and using the the 95 HO Though I have over sized tires and may have to stick to the 2.72 gears..

That is much more plausible. I believe the 3.08 gears are the best for our Eagles with stock size tires. They help the heavy car get up and go at low rpms (using less gas at low speeds) and don't sacrifice much at highway speeds either. Couple that with a manual as well as the added efficiency of a newer 4.0 and things start to look up.

Any plans for a TBI/MPFI conversion casper? Maybe even ignition upgrade? I'd be curious to see what your numbers become then.

not sure if im going to go do all that stuff yet. haven't had a real need to. maybe when ignition dies, I might go hei. but I don't plan to go any injection system. not anytime soon anyway.

If there are any early 80's mustangs with the I6 at a yard near you, you could get most of the makings of the Motorcraft upgrade. My 8mm plug wires are from a 30 year old junked mustang and they are worlds better than the crappy new Xact wires I had.

as an automotive tech, I refuse to reuse any plug wires. you ever see what happens to old plugs/wires? ever see what carbon tracking is? plus, any wires that old will be dried out, and not 8mm wires. those wires (especially if they are a silicone wire) is around 10 years old or so. MAYBE 15 years tops. but still, why bother with those, when you can get belden wires for about $12-15 for an eagle? pointless. yes, I have a high output coil. no reason to go with the big cap. no experience with cross spark on this one, as I don't spin it up to 6k. use stock icm, high output coil, 8mm belden wires, with a .045 gap.

The wires I found at the yard say 8mm on them and they aren't dried out (yet). They are much higher quality than the $15 ones I bought new that pulled the terminals out every time i removed them. Only cost $5 and the car runs better with them, so it was worth it to me. I have not noticed any carbon tracking, but I'll keep an eye out.

I just looked up those Belden wires. I've never seen them before, but it looks like lots of Jeep guys like them. I'll definitely have to grab a set in the future.
