35 MPG Duster

Back in the day, my 318/904/2.73 7/25 rear Gold Duster could get as good as 25 mpg, says my Dad before he gave it to me. I never verified that, but believe it to be so. 35 would be quite an improvement, but very difficult, IMHO. My 2003 Honda 4 cylinder 5sp Accord gets 35 mpg on hwy, if I drive the speed limit.

I think it's not too far fetched based on available tech and weight of vehicle. ( just expensive )
I would guess that it would need fuel injection, ignition computer and a 6 speed with some carefully calculated gearing and timing curve to make it accelerate quickly and be at a low enough rpm to get decent MPG at hwy speeds.
My best guess would be about 6K to buy the parts, but no clue on what the time would be to get it to work....but how long would it take to recoup the cost in gas???? but, but, viable alternative for "buying" a 35mpg car for 20K
