Chassis / Engine Decode Help Please
 

In my search for a pre-impact car, I have come across a 1971 911T in white (originally pale blue ?) with a 2.4 engine on Zeniths.

I know this is not an original combination, but would appreciate if someone could decode the following for me, so at least I know what the chassis and engine were originally. It also has a dog-leg 901 gearbox.

Chassis number 9111102406, engine number 6123836
