Help w/ Engine #'s
 

I'm trying to determine what engine is in my dad's 911.

The verticle numbers look like *63D5//64

The horizontal ones are 930 10


Thanks-

Those numbers don't look right. The engine # does not have letters in it. The 63 might be right but the next number is important. The last 4 are the sequential serial number.
The 930 might be right but the 10 part doesn't jive either. Can you have another look. Use a flashlight and someWd or something to clean the numbers up.
The first 930's were in '76 and started with 686 but the engine type was 930/51.
It is a turbo, but what year is yet to be determined.

I actually did use some brake clean and sandpaper. I then parked it in the bright sunlight. Pretty positive on the numbers.

The engine is a 3.0 and is suspected to ROW.

closest I can find is a 64Dxxxx which is a 930/16 which is a non-turbo 3.0 SC. How about the VIN?

The vin's not going to help here seeing as this engine is not original to the car.

What I'm basically trying to figure out is whether this is a us or row engine.

a 930/10 is indeed a ROW 3.0
9.8 CR, big intake ports, 204hp

The Type 930/10 engine is the '81-83 SC ROW 3.0 w/ 9.8:1 compression, originally rated at 204 HP.

I have one in my '68.

Thanks guys. Do these engines run similiar heads and intake to those of the 78-79 usa engines?

Yes.
But the CR is lower on the US.
8.6 : 1 Me thinks.
The Bosch FD and WUR are slightly different but compatible.
Do you still have the pump?

What pump?

The US '78-'79 have a big air pump for emission control.
Not sure if the Euro's had one?

The air pump was gone on my '83 930/10 engine when I got it, but the air injection nozzles were still in place in the exhaust ports, and the tubing led back to the engine bay, but was plugged off there. I removed it all and plugged the ports to install headers (the air injection manifold interfered with the fit of the headers.)
