I wrote 2.2l the small l is for liter yes i think its 4:10 but i have 32" high 15" tires in the back so the rpm is about 3100 at 65mph the price för 1 liter 95 is 2 dollar i have curved the dist and i agree cam swap is the solution to the problem
3100 at 65 is somewhat high (for mileage) My old 70RR with 3.54 used to run about 3K at 70 and I would not wanted any higher
If I did the conversion right you mileage is about 10.6 miles per gallon. Yea. Fairly dismal, although there were LOTS of stock pickups getting only maybe 12 mpg "in the day." But many of those were 3/4T and 4x4 and so on
Can you go to larger rear tires? I say change the cam, check the distributor curve and timing, read plugs to see what the jetting looks like and BE READY to put a taller hear in the rear axle
