Did a quick search and found people were getting between 11 and 20 mpg with a 235 (or 261) depending transmissions and rear end ratios. What mileage should I expect if I decide to put in a stock 235 with the the original 3-spd transmission, 3.55 rear, and fairly tall tires 215-85/R16)? My truck is a 1950 Chev 3100.
Thanks.
