330 GT Registry

Serial Number Locations

There several numbers associated with each 330 GT.  Some of these numbers are required to obtain an Original Vehicle Colours document from the Ferrari Owner's website.  For more information, please click here.

The main one is the Ferrari chassis serial number.  This is stamped into the front member near the mechanical fuel pump.  The actual chassis serial number is the *8755* partially covered by the header at the middle right.  When I purchased the car, the title had 'GT8755JGM3850M' for the VIN.  I didn't do anything about it, even though it had a J for the I and was missing a number.  However, a few months ago I decided to get that fixed.  After checking with a couple of other 330 GT owners here in Washington, I found that their titles just had the 4 digit serial number on them.  So I sent an email (isn't the Department of Licensing in Washington state modern) explaining the problem, including these two pictures.  I got a quick reply saying that they would research the problem and get back to me.  A week or so later, I got a call and the explanation that they no longer had the background information from when the Washington title was created.  So I had to go to the State Police vehicle inspection station with the car to have everything verified.  The officer there was in a quandry.  I explained the issues.  Then he spent some time looking in some VIN identification/location book they have and it didn't help.  After looking at my pictures and the numbers on the car, he finally asked me what I wanted the VIN to be and I replied with the 4 digit serial number.  A couple of weeks after sending his form and the title to Olympia (state capitol for those of you long since out of school), I got the new title with the right serial number.

The IGM 3835 OM stamping was always a mystery to me until I downloaded the homologation form (from the Ferrari Owner's site) for the 330 GT.  IGM is for Ispettorato Generale Motorizzazione Civilie e T. C., which I presume is an Italian government bureau dealing with motor cars.  The Certificate for the 330 GT, issued December 28, 1964 is number 3835 OM, thus IGM 3835 OM.

This serial number is also replicated on a plate which is pop-riveted onto the body in the engine compartment.  The two locations are just to the left of the hood catch and near or on the sheet metal covering the right front strut.  The '209' is the motor type, not the motor serial number.

The type 209 engine serial number (the same as the chassis number unless the engine has been replaced) is stamped on a machined surface on the right side of the engine above and just to the rear of the starter.  There is also a 'numero interno' number that is stamped above or near the serial number that is the Ferrari internal engine number.  You can see both in the picture.  The 'numero interno' is the number that the Ferrari Owner's site wants for the engine number.

The internal engine number on a 330 America is in the same place, but still used the format from the 250 GTE.

The Pininfarina body or build number is stamped on practically all of the body parts.  It's also written on the undersides of the rear seats, leather and fiberglass parts.  The picture shows the '592' stamped on the door panel.  Some of the parts (side vent pieces) have only the last 2 digits stamped as the area was too small for more.  This numbering let Pininfarina keep all of the parts straight for the bodies under construction.  Most of the parts were somewhat custom fitted, so having the right parts for each body was paramount.

One of the easiest places to look is on the latch part of the hood.  The lower pictures shows '356' stamped on the latch.  The nice part about looking here is that it is easily visible when the hood is raised.

The 5 speed type 571 transmission in the series II 330 GT also has a serial number.  The stamped number is very faint (not on a machined surface) directly below the shifter on left side of rear housing.  There are several numbers which are cast into the various parts.  However, these are part numbers, not specific to a certain transmission.

The 4 speed/OD type 571 transmission in the series I 330 GT has the serial number in about the same location.

The type 508F transmission in the 330 America has the serial number in about the same location.

It is possible to see this from underneath with the transmission installed.  By positioning a mirror on an extension handle and looking up to the left and forward by the rubber donut, you can see the numbers (in mirror image of course).  This is done best with car on a lift, but can be done on jack stands if you have it high enough to get under it easily.  The arrow points to the underside of the place where the number is stamped.

The serial number is pictured in the mirror (reverse image of course).  I can't believe that this picture actually came out.  The flashlight and mirror were being held in one hand with the digital camera in the other.  There wasn't enough light for the auto-focus so I had to pre-focus the camera and hope that I didn't move it too much.  Not only that, but you can read the numbers, 162/66.  Although it does help to look at the picture below.

One can also see (and take a picture) of the transmission number by removing the access plate on the side of the tunnel.  You need to remove the driver's seat, pull up the tunnel cover and then remove the access plate.

The type 571 differential serial number is stamped on the left hand side just forward of the filler plug (right side of picture).  The number '393-65' is probably for the 393rd differential of this type (1965 revision).  The '8 X 34' is the ring and pinion gear ratios.

The series I differential has the serial number in the same place.

The 330 America has the differential serial number at the rear by the drain plug.  This can be seen by looking at the differential from under the rear bumper.
