I had that particular duster 15years ago. I do not know the rear end ratio, it was a 7 1/4 , no doubt, I raised back roads 50-55 all I ever did.Say Barbee, do you recall what final drive ratio, or the cruise rpm , so I can correlate to my combo?

this rear should be 2.76 but i will double check it.I had that particular duster 15years ago. I do not know the rear end ratio, it was a 7 1/4 , no doubt, I raised back roads 50-55 all I ever did.
Your driving style will also have a lot to do with it.
just checked it. 2.94THAT.....is 95% of it....

this is something i always believed. though alot of them were mutts and guzzlers.driving skills does alot.I have had several slant dusters, most were auto, and with GOOD engines driving strickly back roads at 50-55, I figured a good 20 mpg. upeers toward mid twenties, BUT it took a good engine, inc carb, dist, tuning....
I bought a 67 cuda 4 speed stock rebuilt 383 thermoguad back in mid 90's, it had been totally rebuilt( by an engineer for an oil co) that road raced another cuda. I drove it back to Mo from Ca, I remember it had a 2:94 8 3/4, and I averaged 18 on that trip running 60-70, sometime 75 across 2 lane Nevada........ desert, mountain etc.... BUT it was a GOOD engine!
Otherwise known as "degree the cam".
THIS is what most people I've ever spoken to call it. Search Google you will find scads of info on "how to."

here's the # behind coil 6 225 R 21117 anyone know how to decode it? thanksFiTech is planning to release a 2barrel sub-300hp system in "the first qurter of 2018"...
I would put it on a SL6 with out hesitation.
I think i can do better!here's the # behind coil 6 225 R 21117 anyone know how to decode it? thanks
The challenge for You is that Mopar already "extreme mileaged" it for You, so improvements on the basic package are nearly impossible, the base timing for that package isI think i can do better!
Alot of folks saying it Never got the 36 mpg it was rated for. So i will soon find out!As stated, and it can't be hammered home enough, You're driving methods & skills are at least 70% of the engines ability to deliver efficiency..............................
I'm interested to follow this along, don't rule out some aero experimentation, lowering ride ht. air dam/skirts etc..............................even the rake of the car can haveAlot of folks saying it Never got the 36 mpg it was rated for. So i will soon find out!

Engines are most efficient cruising at or near the torque peak in most cases. A V8 can pull off cruising at 2k rpm. Smaller engines not so much. Even most 4 bangers will pull better mileage buzzing 2.8-3k @ 70 mph then they will lugging along @2k.
