You're arriving at Heathrow at 1:20PM and are connecting on a separate ticket to a flight departing at 2:45PM?
Forget it, just forget it, and rebook your connection immediately. There's one at 7:35PM, which you would make. But the 2:45PM one on a separate ticket? You're not nearly getting through immigration, baggage claim, from T3 to T2 and through security in that time, period.
