1979 F150 Ranger Problem

Hey any help would be appreciated but I just recently bought a 79 ford f150 with the 300 in it and im having a few problems. Any time I try to gun it from idle in gear it will die, any time I turn right even slightly while in gear and with load on the engine it will lose alot of power, the power loss is proportional to that of a downshift but its an automatic, almost like its getting no gas but it happens even when im not cutting it hard and it only happens when I cut it to the right. I can't get above 60-65, even going down-hill and hitting the rpms that are required to gear up it still wont gear up, also around that speed if I try to give it too much gas itll lose power so I cant push the rpms even if I wanted to. Any ideas?

Bogging down, hesitating, stumbling from a dead stop or when accelerating at speed: Defective accelerator pump. Time for a carb overhaul.

Don't touch that carb yet!!
Sounds like fuel pump problem. Pull the fuel line off at the carb and crank the motor over and squirt fuel into a clear jar. It should fill the jar up real quick if the pump is good.

I bought a carb rebuild kit but havnt messed with it yet, I think I have a larger problem on my hands now or maybe I just goofed last night and its something small but I doubt it. I put new plugs and wires in last night and drove up to the parts store to return the oil breather cap they told me was right but wasnt to get one that would fit and they gave me a push in cap with a rubber grommet anyway I headed home and I was almost back when it started popping, sounded kind of like a backfire but just forward of where my feet were, in fact I felt the vibrations on the floor board. Did that a few times 4-5 then it felt like I lost a cylinder or something and it rode real rough all the way home, popped the hood when I got back none of the plugs were popped out but it was smoking a white smoke, not nearly as thick as radiator but it was visible from two places I think. Right around the oil filter and near the fuel pump kinda it was hard to tell.

re-check your firing order...you may have gotten one of the wires mixed up...also check to make sure ALL of your wires plug on the the sparkplugs and go into the cap properly I had one on my truck that the cap wire boot was plugged into the cap but the wire wasnt

I didnt do this whoever changed the plug wires before I bought the truck did

! it was running like crap then once I found that It ran lots better!!

Well the firing order is the exact same as it was before I changed the plugs and wires because I did them one at a time so it was impossible to put them in a different order. I can check to see if all of the wires are on good.
