Tweaking a 1966 F250 for better FE
I need a few more posts prior to being able to post photo's
I could use a bit of help in a front Air Dam for my 1966 F250.
I currently have a plastic one off a 2011 F150 but does not look very good and only extends to inner side of the front tires.
Truck started off with a 352 v-8 and manual transmission with 4.10 gears.
It now has late model F150 chassis, suspension, steering & brakes along with a 213 cu in v-6 and a 6R80 6 spd auto and a 3.15 rear axle.
At the moment the "tune" is more for performance, once that goal is met with a 12 second quarter mile I will shift back to Fuel Efficiency tune.
But as part of the 12 second 1/4 goal I need a bit of better Aero to get me there. Now short .037 seconds to the 12 second goal.
In beginning before the performance tuning and switch to E30 I did manage to pull off 30 mpg @ a steady 65 mph cruise.
