I am on a road trip w/my 5.7 6spd...

[Wang]

I had hoped to acheive 30 mpg... couldlnt get it... but it does get 26-27... and I have to admit at about 75-80 mph.
no a/c running.. windows down most times.  I bet it would if my rear gearing wasnt 391.  65 mph I tach about 1500rpm.(6th)
I am in Florida currently and will be headin' back home sunday. Maybe I'll take it easier to see if I can hit the magic #...

That sounds pretty good. I wish my 3:91 got 27 mpg. I think more like 7 mpg!!! I'll bet that's a nice ride!! Keep us posted!!

You'll get better mpg with the windows up and A/C on.

I considered 24-25 good in my 73 Duster with a slant 6!     And I'd be lucky to get her up to 60! (Downhill)

We installed a 1995 Dodge truck 5.9 with the A518 overdrive in my wife's 73 limelight cuda. It has 3.55 gears and the cruise control system out of the Dodge truck. It gets 29 mpg with the cruise set at 70 mph with no a/c and the windows down. Stock truck computer. We were surprised...and delighted.
Now I need to put the 5.7/5-speed auto that I bought into one of my other cudas.

Hey Hot, did your A518 have a three wire extension housing wire harness?  I got mine out of a 90 B250 van and has only two wires (no lockup converter).  How did you hook it up for the 4th speed?

Welp... home today.  didnt get the 30 I was hoping for,, in fact the Mileage dropped on the last two legs of the trip (thank you southern states that sell 10% ethanol fuel).  25-26 was best on the way home.

Thanks for bringing us along for the ride Wang.    Any rattles or wierd stuff happen?   And did you get a spare tire with you new ride?
