well guys, i checked my MPG tonight, and it seems i am now getting 13.69 MPG, instead of the 6 MPG i was getting with the origianl set up when i first bought the truck.
i rebuilt the edelbrock #1405 carb to be more like the #1406 carb, as per their tech person over the phone. he had me change the .100 jets to .098 jets, and change the metering rods. i did that, installed a fuel pressure regulator and set it at 6 psi, set my timing, and didnt really put my foot in it the last 3 weeks of cruising.
and i went for a little cruise on the turnpike to kind of claibrate my odometer. when traveling 1 mile between mile markers, the odometer read only .9 miles, so it was one tenth off.
tonight my odometer read 129.5 miles, so i multiplied that by .1 tenth, which gave me 142.45 actual miles traveled, and i put in 10.404 gallons, for a grand total of 13.691 MPG.
a lot better than the 6 MPG i was getting.
gonne leave it alone for now, and try to keep my foot out of it and hope the mileage stays in that range.
