Hello,
I have just purchased a used 1988 Mustang GT. I'm having a problem
understanding some parts of the VIN code. The seller said that the
car was a "GT40" but I can't find any reference to that in any of
my Mustang reference books. The VIN is 1FABP42E7JF233253. The VIN
says GT 3 door coupe but the engine code of E doesn't show in any
of my reference books. I called the Ford hot line and they said
that an 1988 E code was a 5.0 HO EFI 302ci gas V8. They also said
all records at ford are purged after 10 years and the 1988 records
are gone. Do you have any information on a "GT40" kit, RPQ, Engine
set, etc., or any information about an 1988 engine code of E?

Hi there 66parts.
I have been doing a bit of research on Mustang codes and VIN's lately for reference here and I havn't found anything about a GT40 option though the E engine code does seem a little strange.

One thing I have found is that there are some strange things that went on with special orders and codes that are hard to track in reference manuals.

1FA -Ford Motor co
B -Restraint system(Active Belts)
P-Passenger Car
42-3 dr GT
E-?
7- Check Digit
J- Year 1988
F- Plant code Dearborn
233253- Consecutive unit Number

I'm still working on things slow though it is and will see what I can find.
If you find anything out about it can you let us know as it will add to the available info.

Do you have one of these E code cars too?.

I requested a feature list from FORD and they said that engine code E for 1988 was "5.0L 320 CID 8-Cylinder HO+ Engine". I'm not sure what an HO+ engine means but it is interesting that Ford must know about the E code even if the reference books don't. I have also found that FORD RACING produces a GT40 engine package per their latest catalog. I now believe the previous owners removed the orginal 5.0 and replaced it with a FORD RACING GT 40 crate engine. Does anyone have any experience with the FORD RACING GT 40 package?
