Sounds like someone is BS'n you.

71 440 4 speed cars ALL had 18 Spline 4 speed transmissions
71 440 4 speed cars ALL came standard with Dana 60 rear ends (4:10 gears were optional)
The leaf springs are standard with that combo
NO 440 made ANY year will bolt onto a Hemi K-member, the mounts are completely unique to hemi cars
SOME 440 cars had Skid plates on the K-members.

If the VIN says it's a U-code it's a 440 car, end of story. Nothing wrong with a factory 440 4 speed Dana 71 car, no reason to hype the Hemi aspect, it's rare enough and good enough just as it is without the BS.

Thank You kindly for your confirmation to my thoughts. I appreciate it. Also the two pennies worth signature on your comment is very cool.

Im a 71 X-fan too. What your describing sounds cool. Especially if its a real 4spd car. Been looking for a 71-4spd X for a good long time that is affordable.

With Chrysler, anything is possible. If you had the right connections, you could get what you wanted.

As far as the Hemi part of your questions....

To drop a 440 on a Hemi K would take some fabricating. I think something like that would not be done on a production line.....Meaning, its more than likely done after it left the factory.

The 4spd should have been an 18-spline with atleast a 3.54 Dana, 4.10's being optional. Hemi suspension was standard an all GTX's. 4spd cars got boxed torque boxes on both 440/Hemi. Its possible a 23spline could have been installed by accident or if inventory got low, but more than likely not.

I'd say someone has had a Hemi in it at one time and used a 23spline trans during the swap.

Or, there could have been a VIN mistake. Which would also be a rare thing to happen when it comes to an engine code.

What other options are on it? it would also have to have N96/Air Grabber. If it has power brakes, it should have a special Hemi only brake booster.

What are the codes on the fendertag.

Where is it locate......

So all the 71 gtx hemi 4 spd cars came with air grabbers??? The point is not there. The point is could Chrysler have because as you put it low inventory suddenly change their minds and used a hemi intended car and slapped a 440 on it? I think that is ridiculous in my opinion if anything for regulations and safety reasons. No? But back then lead gas was ok too.

BTW, in regards to what cdp posted above (he's another respected knowledgable member).

My responses don't leave any room for exceptions.....Which there were with most things Mopar, however, the likelyhood of any of the facts I posted being otherwise are EXTREMELY remote and would require absalute bulletproof evidence to support if someone were to represent any exceptions as "facts".

(BTW, your above scenario about the factory substituting a 440 for a Hemi in a normal production car at the end of the production line? That possibility is so far remote that I feel pretty safe in saying it never happened, and if it would have they would not have left the hemi K-member in it.)

I would agree. I am only asking you guys because although I've been a Mopar person for many decades and owner of a 71 GTX long time ago, I would think the factory would not of made mistakes. Especially putting a motor on a K member that you say would not of fit. I respect your opinion.

Thank You again.

Thank You too sir. I'm only trying to see how and why this would of been said. Also, can anyone explain this:

A picture is worth a thousand words....

I don't think a day goes by when somebody doesn't tell me a story about some Mopar with an impossible drive train setup.

I almost bought a Hemi Cuda vert that wasnt a Hemi.It was brand new on the show room floor.Local dealer had it.The vin window sticker etc all had Hemi codes.It was a 440 6 car.This was brand new red vert.I still kick myself for not buying it as the dealer would have sold it for 3200.It stickered at like 4400.I asked Galen about it and he said he knew of one that I believe was in Detroit.Rocky
