A friend just bought a 69 GTS 383 4spd body and can not find what X21 code stands for.It is an X09 also he says that is also coded for Factory Headers. Would that be real headers or HP Manifolds?

PICS?

X21 = M21 drip trough mouldings??
X09 = Y09 build for EXPORT?? or any possible SPD???

factory exhaust headers, what code is that? - it doesn't exist on a '69 DART

Typo! Code was Y21 for Factory headers

Factory headers on a 69 383 Dart ... I'd like to see a picture of THAT fender tag ...

1969 383 A bodies only came with one type of factory exhaust manifolds so technically, I guess, they would be HP manifolds ... headers ????

I have a real 1969 Dart GTS 4 sped car, what are the exact first five numbers and letters on the VIN? mine has a factory defect on the dash VIN tag, it is over stamped on the two center letters in the V.I.N. The fender tag and door post tags are not My message is Mopar did make errors and mistakes on some of thier cars, not all of them are perfect

Thought I read somewhere that they where Stahl headers shipped in the trunk, never installed.

Not that I have ever seen or heard of, but I don't claim to know everything. I do have a 69 383 GTS .

Well it could be true but probably not. I was alive back then and one of those things that were talked about by the drooling youngsters was, "I hear they come with a pair of headers in the trunk!"

This I heard about Camaros and Mustangs and quite a few others, even Buick GS455 Stage 2s. More likely than not some owner told that lie to the fanboys to make his car seem more special.

It wasn't limited to headers, there were a couple of exotic intakes that were rumored to come in the trunk as well.

So until I hear it from a historian I'll just laugh and say yeah, right!

R.

The 1967/68 Camaros you could 100% get headers as an option and delivered in the trunk ~ RPOZ28BD. I would wager that the other GM divisions offered the same, as well as Ford, & perhaps Dodge/Plymouth.

If any of your 383 4 speed cars are copper colored with a white interior I owned one in the early 90-s and have tons of pics but never was concerned about the vin or ft info...But it was untouched.

I spun a rod and think it was the org. manifolds because the drivers side was the hardest manifold removal id done up to that time, and if I recall I had to cahnge a few plugs from underneath.

Not sure if any other mag. ex manifold worked on that car.

I have never seen X21 on any big block A-Body and I have seen dozens if not hundreds of them. Can you post a pic of the fender tag? My 69 383 4-speed GTS came from the factory with DART GTS stripe on one side and DART SWINGER on the other so yes, there are errors made...

You're talking about equipment for off-road applications, which makes total sense for a Trans-Am Camaro. However, the Dart GTS is a completely different animal - I'd wager the Camaro is one of the few, if not the only one, to have headers as an option.
