what year is the 4.3 motor out of as the 1966 el camino did not come with that motor. There is a difference in camshafts on those and they fire differently. it may be the wrong camshaft.

I screwed up I saw 4.3 not the v8 behind it sorry. this may be a timing issue with the dist in maybe one tooth off.when timing the vacuum advance should be disconnected and blocked. see pic for correct positioning of wires and firing order. then prior to starting if you have air mix screws take them out and spray choke cleaner into the holes then lightly seat the screws then back off 1 and half turns. then see if it still stalls . If it does it's a carb issue like low float level or choke not working correctly. Make sure that the choke plate opens a bit when it starts as well and not pulled open all the way as that may be it as well. that wold be a choke pulloff problem like no vacuum or broken diaphragm.
