Engine number question
 

Hello,

can someone find out what is this engine: #655xxxx

It's supposed to be a 1975 engine but don't match any of my books.

Thanks,

According to elferhelfer.de it is a 75 US California 911. Engine type 911/44. I have pasted the info from there for 75 US cars below.

911 S US 911/43 165/5800 225/4000 9115200001-9115202310 6450001-6452440

911 S Sporto US Calif. 911/49 165/5800 225/4000 s.o. 6559xxx-?

I think it's a typo. If you have the books then you see 645 and 665, so it would be easy to mess that up.

655Yxxx would be 911S/Carrera California.
The 911S and Carrera had the same engine for California.
If Y = 9 then the engine is a 911/49 165 hp for Sportomatic, California.
If Y = 0 to 8 then the engine is a 911/44 165 hp non-Sportomatic, California..

Best,
Grady

Good to know. Patrick Paternie didn't know that. ;)

So, if Smog Man sees 655---- then he's gonna go lookin' for thermal reactors, huh?
