i adjusted the timing and it seems to get closer but it is backfiring through the carb, should i keep adjusting the timing,:(

IF you have a 70's 302 your firing order is 15426378, check it the newer cars are different.

if that isn't the problem it's time to start from scratch with the timing.

do you know how to find TDC on the compression stroke? start there if you do , if not let us knowo and we'll talk you threw it
