Bob,
sorry to have to ask you to clarify more, but I'm confused by what you and Johnrr said. Are you saying that the 054 originally is only a 2 row like the 055? Only difference is the lower tank? If you're "Glenn-Ray" Bob, thanks for the lower tank you just sent for my 70. Looks great. Tom

Mike,
The 055 also has a 12" trans cooler and the 054 has a 15" cooler. Other than the lower tank being bigger on the 054, thats it.

Mike, I don't know if you answered this before but is the 055 on your broadcast sheet?

---

John the GTX is an "E" LA assembly plant car, no broadcast sheet but I'm 99% sure the 055 radiator is the original to the car, it is an original (nummbers matching) 3.54 Dana, 4-speed, 440 engine, even the original wheels and original spare. I think only the 4.10 Dana got the 054 radiator, saw an original 4.10 Dana 4-speed GTX at Mike's B/E&A get together a few years ago with the 054 (have photos....of course ) and another 3.54 Dana with a 055 at the Nat's too.

I think I need to see a broadcast sheet to be convinced. I know the 383 with the A31 package came with an 054. I am sure that by high performance radiator they meant maximum cooling. The literature that I remember used the words maximum cooling system. The 055 also came with a different fan clutch for A/C. I know your car is very original but the 054 could have been switched for a different home at some point?

---

John, I agree that the 054 came with the A31 High Performance Axle Package with the 3.91 8-3/4 and that's what camee with my '69 road runner I ordered in '69 but my '69 GTX is a 3.54 Dana which is the A33 Track Pak.

As for the radiator being switch I can't rule that out. The car title shows me as the third owner and it was almost completely original down to the wheels that still have a set of '70's or '80's BFG T/A radials with the original T/A tread patern. I'll post two photos of the engine in the car untouched with 93,000+ miles on it, one that my friend took when he was told about it and one that was on ebay at the same time as my friend was looking at it (that's another long crazy story too).

Let me know if it looks like an original radiator and if you can tell if it's an 054 or 055:

Photo from ebay no sale:

(Remember this is a California silenced car with no chrome tips either)

LOOK AT THE RADIATOR CAP AND THE DIRECTION OF THE OVERFOLW TUBE!!! NOTE THE ANGLE

and here's a 054 LARGE FONT radiator in an A31 High Performance Axle package road runner (just like you said John ). And in this photo something should jump out at you that if the first two photos that I posted are of the original radiator, to my GTX then it is an 055 in the GTX

Mike, if you don't have any BS pics, I'm sure Dan, Doug or Barry do.

Basically ALL 383/440 optional axle packages (A31, A32, A34, A36), trailer towing (A35), Hemis and cop cars (BK or WK) got the 054.

A33 was 055.

Thanks very much for this info as well as the FSM info you posted in the Q&A A33 thread. https://board.moparts.org/ubbthreads/show...e=0#Post6920208

It is great info that certainly cleared up a lot for me!

Here's the FSM for this thread showing 440-4 speed was 055.

then what makes or desinates 055, mas cooling? Broadcast sheet? 440, with 4 sp,, is 055,, but what options make that override to 054? axle ratio? what package pkgs?

---

For sure the 4.10 DANA gets the 054, I have a photo of a '69 4-speed 4.10 ratio Dana with a 054 radiator that is original to the car and it is small font with a Lynch Road SPD of 1 29 (Jan 29, '69).

I would say the axle ratio and type/size is at or near the top of the radiator spec list, then A/C or trailer tow of course but after that I don't know I don't think that power brakes (disc front or 4-wheel drums) would require more or different cooling needs?? What else is there unless there is a "tropical" option that goes with the "heater delete" option????

(I'll probably learn something here again today like I do everyday on Moparts )

What's odd is the 440 with 3.54's got the 055 but a 383 with 3.55's got the 054 ???

---

That is odd

I wonder if Chrysler was just trying to get rid of stock and obsoleted the 055 2-row 26" radiators?

Radiator Bob said he has never seen a small font 055 radiator and I know that the small fonts first started to show up on Lynch Road cars near the end of Jan, '69.

A 3.23 8-3/4 with or without Suregrip got a 22" radator (without A/C or towing), a 3.54 Dana Suregrip got a 055, a 3.55 Suregrip got the 054, a 3.91 8-3/4 got a 054, a 4.10 8-3/4 and 9-3/4 Dana got the 054 and we never saw a small font or a 2-row 26" radiator again........making that last part up or is that true. What replaced the 055 2-row 26" radiator in 1970???


What was the extra space for in front of the '69 2949 055 and '68 28980 47 radiator for, air space for the A/C condensor

So, if you specified a 4-speed when ordering your new '69 GTX or RT, BUT did not want an axle package, then you got a DANA with 3:54 gears minus the requisite "max cooling" that would have been included were you to have ordered an axle package? Thus, your car would have had the 055 radiator installed?
Very interesting.....

I always thought that a 4-speed GTX,RT, or 440/426 Charger RT automatically came equipped with an axle package?

While the A33 does include the 3.54 Dana, it's not necessarily considered an 'axle package' like the others are.Odd...but true.

Here are the pages from the 1969 Dodge data book and price list. The A33 info does not have the word "axle" or any specific rad reference.

On the sidebar info A33 is the only one that states "required" and not "available" and as has been noted the word "axle" is NOT used...you guys are good

Given the originality of your car, the sample broacast sheets and the FSM, it gives you every reason to believe the 055 is original to your car. The Photos and FSM would suffice if any judge questioned it. I think that the Dodge accessories data you posted would still raise questions if you didn't have the other references. The Dodge info indicates that the A33 package has a 26" High Performance radiator and fan shroud that is (STD. Hemi). Must be an oversight or false advertising! IMO, I don't think you need to question it any further. It's just that the 3.54 really did not come with max cooling otherwise known as the HP radiator as advertised.

It was always my understanding that with respect to the GTX, RT, & 440/426 Charger, there was no standard axle when ordering a 4 speed...You had a choice of the two axle packages, and that was it.

The 055 radiator now cleaned and painted, with the 305 8 (October 31, 1968) date code. The GTX has a C16/December 16, 1968 Scheduled Production Date so it is close enough to be the original and I still believe it is the original radiator to the car.

Why didn't you keep the original California air cleaner on the car? Are you installing chrome exhaust tips?

---

Don't want to go OT but I like the sound of the unsilenced air cleaner cover and the exhaust tips and even thinking about putting an "air grabber" system on it. Had the dual snorkel on it.....another thing is that darn big dual snorkel air filter cover his HEAVY too and I'm sure it doesn't flow enough air to feed the Holley 770 under the unsilenced cover on there now took the stock road wheels off and going to redo them, put a set of G-70 red lines on them and go do a pure stock event or two......do I have to put the dual snorkel cover back on for that

Oh this is the GTX with the 055 radiator, 4-speed, 3.54 Dana to keep this OT

Day Two now with the tips

So I guess we can conclude from this that the 26" radiator used in axle packages is not always the max cooling unit. I also looked in Galen's parts book and, sure enough, the 055 was used in 440 powered 4-speed b-bodys "less max cooling". The only other application was for a/c cars. I guess max cooling and axle packages don't go hand-in-hand in this instance. Still, one has to wonder why...... life is a mystery....

---

It all makes perfect sense to me except if the 8 3/4 cars with 3.55's got the 054....that's odd. I suppose the rationalization is that 3.55 is an optional axle package gear on the 383 cars (standard is 3.23) where the 3.54 is the "standard" gear with the 440-4spd.... Doesn't make any sense from an engineering perspective, but it does have some twisted logic from a sales perspective.
