Thanks to everyone who offered help. Had a twofold problem, one being the fuel delivery which was fixed by removing the old inline filter that I didn't know I had, the other was the distributor which was equipped with it's own governor. When I got the truck it had the original governed Rochester carb on it which I swapped for an AFB but I had no idea the distributor also had a governor. Anyway the Pertronix distributor fixed that one. So now the old 409 runs like a champ and has the power I hoped it would have. Thanks, again, to everyone.
