Hello everyone, before I begin i would like to say that I have been digging through the forums about this for a few weeks now and haven't been able to put my finger on this problem. I have recently purchased a 1989 grand wagoneer with the amc 360 in it. Here are a list of repairs the Previous owner has done:

whats going on: when I bought it, it didnt run, just turn over. upon looking in the engine compartment I found the coil and dizzy were not wired in right so i replaced that. I also have replaced oil, plugs, oil filter, fuel filter, spark plug cables. The carb tsp solenoid was not hooked up so i fixed that and also replaced vac hoses and repaired a leaky evap canister. i believe it has motocraft 4300/4350? i am unsure because the stamp on the linkage side is worn off.
those fixes had gotten it to start up and to idle rough.
I next used a dial back timing light to set the initial timing to 12 degrees btc as per the sticker in the engine compartment. That enabled the engine to idle a lot smoother. I tried to drive it and here is my delimma, it dies when throttle is applied and will not go above 2000 rpm without engine noise, backfiring out of the exhaust and sometimes out of the carb. I played with the timing a bit trying 12, 14 ect all the way to 30 degrees btc for initial timing and it smooths out more the more it is advanced, but still dies under load at higher rpm. I next set my timing light to 34 and raced the engine to engage the mechanical advance and set the timing that way. that was a bit better, but it still hesitates a lot, has excess vibration and dies under load with high rpm unless you baby the throttle really slowly increasing rpm, then it still has a lot of noise.
I am unsure of what to attempt next maybe my dizzy needs work or another underlying issue is there? please help me out!
