Aside from 1972, I was wondering what the rarest 6BBL/6-Pack MoPar would be?

You said nothing about it being a production piece,... So, it would be Tom Hoover's personal 66 Coronet sporting an experimental FACTORY 426 HEMI 6BBL induction system for FACTORY testing...

Probably a 70 Coronet Vert or a 71 Cuda Vert?

Or maybe the Sport Fury GT's?

Rare can be tough term to nail down. To some that is the most valuable. To others it's desirable and rare options combined with value.

Most valuable is a 71 440-6 Cuda conv.

Rare would probably be a 70 or 71 Challenger sunroof 440-6 with 4spd. I don't know of one, but I'd guess they made one. I'd imagine from there it would come down to desirable options like shaker, louvers, rubber bumpers, color, etc....

But there are 70 Charger 440-6 sunroof 4spd cars too.

There seems to be more 71 Charger sunroofs than any other 70-71 car. Maybe others can chime in with an opinion on that statement.

Sunroof 71 RR's and GTX are very rare too.

Forgot about SFGT's. But they are all autos. The biggest thing I can think of that would make one stand out from others is color. So Dan's old TX9 black SFGT 440-6 would probably be the cream of that crop? Are there any other options that stand out on those? Sunroof?

Trans am car with 3 fender tags, how many have you Guys ever seen?

This Challenger would be a honerable mention, but I think automatic holds it back.

I was just thinking 440-6 cars.

I'd think the rarest would be the sunroof Challenger T/A's. The one documented one is an FT6 brown and an auto. There is a reported (still only reported?) lime one.

There are a number of rubber bumper louver 4spd AAR's.

Is it even possible? Challengers are really hard to get to the extra tag. I have three highly optioned Challenger R/Ts and only one is a two tag car.

He's counting the "Trans Am" tag

Morty426, do you know of any 440-6 Challenger Sunroof 4 speed cars?

There was a 440-6 Challenger sunroof advertised for sale near Carpenteria CA 5 or so years ago. Thought it was sublime? Don't know trans.

see the ad above, a 340 super bee, wooops.

I like the pink Challenger and the lime Coronet R/T

only one is known to exist..

I know he's counting the "Trans Am" tag as #3, but it's very hard to get a Challenger to the second tag.

There used to be a F8 green Sunroof TA in Vallejo. I missed out on that one.

I do know where a B3 U code sunroof Challenger is here in Sacramento.

I don't remember a V code sunroof Challenger and Carpenteria is a dangerous place to have a car rust wise.

I do remember this car, but it's a HEMI

I'll go with that one......but if were going with a vinyl roof one off option then sunroofs, color and other options will have to also come into play as for rarity. Verts already have one up on the 6BBL/6-Pack as there are fewer convertible models ordered each model year or model line.

When you are dealing with cars that have production figures less than 200 with the number of options and paint choices I think it's less like that two cars got built the same.

Are we including options and color then?

I think that is the green T/A Sean Machado once saw. Same area. Was it an auto?

My 71 Challenger R/T is 2 tags. It's not particularly rare or anything. Not really loaded with options. Just all the molding options. And those can fill a tag quick.

I think this might be the Tom Hoover 426 HEMI 6BBL intake manifold a 3X2 carburetors......took the photo along side of the original Edelbrock 3X2 aluminum proto '69 A12 intake manifold.

MikeR

I don't know of one - are there any known 3-tag "TRANS AM" cars?

if "WE" go by just 3x2bbl intake, transmission & exterior paint combinations there are going to be dozens of KNOWN "1 of 1s"
