Thanks, but I've done that. I had the transmission and engine rebuilt. I put a new torque converter on it the other day. I put a new exhaust on it three years ago. New MAF a couple months ago. I checked the fuel injectors and they are good.

Hello... your secondary CAT on the exhaust manifold could be clogged... its a major flow restriction and power robber if it is.. :)

Thanks, but I have disconnected my exhaust system and driven my truck and it did not make a difference.

If the truck bucks at around 40 MPH as the diaphragm in the secondary actuary fails. There are some tricks to get around this problem. I added set screws to hold it open. That worked nicely. To replace cost over $100. Oh you have to remove the carb to get to this park.
