I appreciate you responding, but I had my face in it and it was stamped 2:92. Weird, but true.

G'Day,
Just a Little Info.
A Few Years Ago One of My Club Members Decided to Change His Diff Ratio From 3.23 to 2.76.
Within a Few Months He Changed It Back.
When I Asked Why He Said That Every Time He hit a Head Wind or Came to a Not Terribly Steep Hill He Had to Pull it Down a Gear.
Not Impressed!
(And He Didn't Find Any Really Substantial Fuel Savings, I'd Assume Due to Lack / Loss of Pulling Power)
His Car was a 65 Plymouth / Dodge Phoenix with a BB 318 & 727
I Have Been driving MOPARS in One Form or Another Since 1966, The Vast Majority Were 3.23 Ratio's.
And I Can Only Say That Unless You're Doing a Heap of Long Distance Driving Stick With the 3.23s.
Mother MOPAR Knew What She was Doing.
3.23s are the Best Overall Ratio for Normal Driving.
I Can Remember Blowing the Doors Off a Newly Released Turbo Charged Volvo Many Years Ago with a 383 69 Phoenix.
Boy, Did He Look Surprised !
What Follows May be Certified as "Long & Boring" if So I Apologise But the Story Must be told.
Many, Many Years Ago a "Friend" Called Me From a Country Town Many Miles Away.
He Complained That I Hadn't Been Down to See Him For Ages.
I Explained That I was Broke, His Reply, Come Down I Owe You a $100 so That Will Pay You Fuel Home.
So Off I Went, Filled the Tank Before I Left and Rolled into Town on the Fumes left in the Tank.
Filled the Tank as Soon as I Hit Town and Then Drove Around for a Couple Days Etc.,
Came Time to Leave, Asked Him for the Money, He'd Put it Into the Poker Machines at the Local Club.
( I Suppose Most of us Have Had Friends Like That at Sometime in Our Lives)
So Here I Am Stranded Over 400 Miles From Home with 3/4 Tank in a 383 BB Powered Dodge.
Wasn't Much I Could Do, So I Set Out For Home Promising Myself I Would Not Exceed 50 MPH.
Sweated All the Way But Amazingly I Made it.
( If I Could Have Changed the Direction of the Curses From All the other Drivers Behind Me
I Would Have Breezed It In.) LOL
When I Did My Sums I Figured I Must Have Achieved Around 22/23 MPG.
Moral of the Story
1. Pick Your Mates Carefully. (Wasn't the First or Last Time He Let Me Down)
2. High Ratios Are Economical But They Take a Hell of a Lot of the Fun Out of Driving.

Thanks Tony. I think I'm staying with the 3.23.

3.23's were godd back when the speed limit was 55. Then highway driving and interstate driving are two completely different situations. Around here if you don't drive 80 on the interstate, you will get run over! Go ahead and run your 3.23's at 80 for 4 or 5 hours and see if you change your mind. JMO.
Indeed, the 2.56 acted like overdrive, the wagon didn’t prefer 55-60mph but felt sprite between 70-90 mph. Around town she was still quick enough especially for her size.
Ideally I’d like my 67 crown to have about 3.55 with a 4spd auto overdrive. Whew

Or a 3.91 with overdrive.
The 4sp usually gives you a quicker 1st gear than a torqueflite or th400. Great thread, the debate rages on! Whew
