Well heres the update, The driveshaft was out of round and off balance. The shop redid both ends and balanced it. It didn't help my problem though. This weeked I replaced the torque converter with a new balanced stock unit. It to didn't help the problem. We spun the distributor,HEI, on a machine, checked wires and cap and found no problem. I install a new points unit I had, no change, new plugs, no change..
I have two shows to go to in October which are close to home, after that I plan to pull the engine out if I can't come up with a solution by then. I don't really know what to look for once its out, in runs so good with no load on it. Last tank of gas it got 19 mph with three carburetors!
The truck should really be smooth when I get this solved! Joe Hand
