Engine id

Hi all after buying what I thought was a 2011 te310 starting to strip engine and it turns out to have a 250 barrel on it (79mm) can only assume a engine swap somewhere in its life has a txc 250 ecu and green injector but have learnt this is a common mod,can anyone point me in the direction of finding out what I have cant make engine number out only a3****427!! I assume its a 11/12 xlite as has single exit exhaust from head any help greatly appreciated or any tips to see that bloody engine number!!

Think engine number is A3AB00427?
