I have a 1979 ford f150 4x4 built from ground up i hab a 2 barrel carb i took it off and put the 4 barrel carb and when it is cold it running great but when it warms up it has no power at all any ideas on what it might be

 

Welcome to the site..

Ground up,, meaning engine build, cam replaced? Who's manifold, carb? Or was the 4bl just added onto the stock engine? No power at all when heated, meaning just poor/unstable idle, idles fine but lack of top end, flat spots? Replacement carb was used, rebuilt, or new?
