Backfiring is typical for 'lean' conditions and stuck inlet valves.
check also the spark plug condition, replace them if any doubt on their age exists.
Check compression to discover open valves.
Clean out the carburettors.

Engine running cold


Is the radiator cooling fan(s) running full time? Could have been mis-wired during engine swap.
