Engine size recommendation

The rear end ratio is going to make more of a difference than either engine.

I got 26 inch tires and 3.91 gears in a 3,700 car with a 10 inch converter. I get 8 to 12 mpg, yuk. I getting taller tires next time for it.

2.94 gears at good on the freeways, traffic seems to be going 75 mph now.

I recall the drive 55 days, U went 62 mph and got 20 mpg with 2.71 gears. If U were not winding it out, lol No cell phones were great
