thanks for the response, I have decided to convert the 4.3 to a 2100 carb with hei vaccum advance distributor, I dont think i will be happy until i do, I'm old school, I just finished installing new window and door rubber seals, I actually wanted to do an engine swap to a small black chevy v8 and auto transmission but after I found out that I could convert this one I decided to give it a try, I want to thank everyone who took the time and responded to my request for help.
