What a Peach of a car ... your looking at Strugs. Very nice.

as for the Engine number, this number your showning seems to be a part number and not the Engine Number.

If you wondering if the Engine is the original Engine it should look like this, 6130001

6= 6 Cyl.
1= 911T
3= 1973
000X= Sequential Numbers

The V.I.N number on the Dash Plate should look somethinglike this,
911.310.0001

911=Type
3 = Last digit of year
1 = T, 2=E and a 3=S
0 =Coupe and 1 = Targa
000X is for Consecutive Chassis Numbers

I hope this makes sense, If you need to know where to look for the Engine Numbers let me know.

Good Luck.. Jorge (Targa Dude)
