I hate to see your disappointment on this. Following your build thread all along it's seems you have been either in the wrong frame of mind or you have been unrealistic in trying to keep it as "original" as possible. These old work horses were never speed demons. I know you've done a ton of work. Bravo! I've seen you state some prices of parts and fixes that were unrealistic in my mind, but to each his own. Now maybe you see why people will use these cabs and not much else of the "original truck". If you are intent on getting more speed, I would suggest a change from atleast the motor back. Used prices for another transmission choice, an updated open drive shaft, and rearend with some usable gear ratio would cost less than 500 bucksnorts around here and we aren't that cheap on prices in this area. I know that you may think another change of this sort is alot of work, but it will allow you to "like" your truck a little more. Just my honest opinion which don't amount to much.
