Carb jetting and condition will also have an affect on milage. Also Double Pumper Holleys are very thirsty so don't go that route if MPH is important to you.

Your car has an 8 3/4 differential. It could have 2.91,3.23, 3.55 unlikely - gear ratio
2.91 will give the best fuel mileage. Look to see if there is a metal tag under one of the bolts the original ratio will be stamped in it..
