1974 911 Question

[nealf2002]

Hello- I'm going to look at a regular, non S version tomorrow and wondered what a numbers matching car means? Which numbers are supposed to match? The VIN and engine numbers are different, correct? What should I look out for and in what location of the car would I find?

Thanks.

don't worry about the numbers, worry about rust. 74 chassis are just as prone to rust as the longhood cars. poke around everywhere, especially the front and rear suspension mount points and the rocker panels (jack points)

a '74 non-S coupe, chassis # 91141000001-9114104014 should have a motor from 6140001-6146625 and be of type 911/92 the trans type should be a 915/06

Matching numbers means that the car has the same engine and transmission it left the factory with. There is a slight value increase for this. You can order a Certificate of Authenticity from Porsche which should give you these numbers. If the numbers fall in the ranges given above, then you most likely will have the correct engine. It isn't a certainty though.

Thanks for the replies. 2 more things,

1) the car has the US spec rear bumperettes. Shouldn't 74's have the smaller ones?
2) what is the correct side mirror for the '74? I know these have been replaced but wondered what stock was. One driver side chrome? No pass side?

Thanks again.

1. Yes, all 74s had the smaller bumperettes.
2. Chrome driver side only, though I believe a passenger side mirror was an option.

Terrible advice IMO.

Matching numbers is 10-15% of value, the same as I'd apply to a color change.

That is on TOP of what ever the car needs in the way of repairs and freshening.

Agreed, 74 is the best year for the 2.7 without all the smog rubbish so check it out.

All 911's should be carefully checked for rust. Galvanized cars are less susceptible to rust but certainly not immune. FYI the pan, rocker panels, suspension points and some other areas of '74's are galvanized.

They are? I didn't think any galvanizing came in to play until 76-77?

Love my '74. Things to look for - what struts does it have (Bilsteins are green, Koni black, etc) Does it have a front oil cooler? (non S probably not) Rear sway bar (non-S maybe not) AC ?
'74's were not galvanized. If it's a PA car, it will have some rust depending on if it was driven in the winter. It can all be repaired if you've got the time and or money.
Engine work has been covered in many a thread. If it's done they're fun lil' runners.

Lots of confusion on this issue but this thread seems to cover the galvanizing progression in the 911's:
