Thanks for the info.
My plan for this truck is to drive it. It see's a good deal of Interstate travel. I live outside of Nashville but work inside Nashville. When it's more driveable we will probably put 500 miles on it a week.
I know I will never see 20+ miles to the gallon but I know I can do better than 12. The stock carb is giving me fits. It's a 1 barrel...probably rochester. I rebuilt it months ago but it has never been set up properly. I think the air horn is warped. tonight it was running terrible. I took the breather off and the idle jumped waaaaay up. The breather is not dirty. It didn't do this a week ago. This is new. Some of the trouble, maybe all, could be the trash I found in the carb a few days ago. working on that fix from another post.
I think the timing and points are set right. The engine starts instantly. I am looking for another rear axle with higher gears.
Would I be better off getting a 2 barrel and would it fit my intake? How much$$$???
