Could someone please help with identifying this early 911 e

[steveSC]

Hi all.
I have had a disaster recently in that my garage caught fire and destroyed the roof. Unfortunately I had my project Covin inside at the time and the falling ash/debris has damaged the paintwork on the car. (Don't ask about claiming on the insurance as they don't want to know which is another story.)
Anyway the car is fitted with what I believe is a 1973 911t engine and a 915 gearbox. I am probably going to sell the engine and gearbox, along with the genuine Fuch 16" x 7s and 9s wheels. Luckily the engine and box have not been damaged at all and remains in excellent condition.
Here is the number that is stamped on the engine next to the fan housing and the number has a star in front and behind it.

*6531086*
The other number just behind this reads
911/57.

Any help at all with this would be greatly appreciated as I would like to know a rough price to be able to advertise it for sale.

Thanks

Steve

That 911/57 engine is a 1973 Euro-spec 2.4T version that was originally fitted with Zenith carburettors.

As I am unsure as to what value the engine and other associated parts are worth I have decided to advertise it on ebay. Item number 112451063269 if anyone on here is interested,
