Can anyone say for certainty which of the two different 8 grand 70-71 E-body tachometers were used in which application.
Was the 5500 redline used in small block Cudas and Challengers, and the 6500 rpm in big blocks, or was it a 70 and 71 thing, or perhaps auto verses 4 speed.
There were two different versions but both carry the same part number...5500 redline..

....and the 6500 redline rpm tach.
I have seen more of this version in a variety of 70-71 E-bodies....
Colors have faded a bit but both are untouched originals.

Definately two different color patterns, unless I've got the only one in existance.
70-71 E body guys with 8G tachs, take a look.

If anything I would say you have it backwards, a small block can out rev a big block.
Were there any 8 grand tac's for early 72?

Just asking, thats how we learn about these cars. If you saw these two in person you would see what I mean.
There is a glaring difference
So far two others have contacted me with the same two different tach faces, one guy claims it was bigblock verses smallblock.
Hopefully we'll hear from more people.

For the record, take a look on the back of a 7 grand tach, 2984185, and on the back of an 8 grand tack, the same number..2984185.
Parts books, 70-74 show the same part number when ordering, 2984185, yet they are 8 grand and 7 grand tachs.

Hmmm, never noticed that one before. I see what your talking about. If I get a chance I'll look at some tachs I've got laying around. Unfortunately they're not in cars.

I've heard of companies that re screen your tach face from a 7 grand to an 8 grand unit. Are you sure these are both unmodified examples?

There are definately two different 8k tachs as far as redline colors. I don't know if we can ever figure out the exact reasoning, I would be VERY surprised if it tied into BB/SB. I would say most likely it was two different vendors? Are the 5 digit vendor codes different on them? Aside from alot of 72s have 8k tachs with the resets through the plexiglass, I had a somewhat early 72 Rallye with resets throught he woodgrain, and date codes on everything showing it was original to the car.

These tachs are untouched. I removed the complete clusters, from two red Cudas in Dobbins Auto Wreckers in upstate NY in 1976.
If I recall, both were 340 4 speed cars and had the two different tachs.
Numbers on the back of these tachs as well as all 7 grand tachs I have and have seen, are all the same 2984185, beneath that is 04091 which I would assume the vendor, then 300532, then 960-BK.
If anyone has anything different on any E body tach, any year, it would be interesting.
Only difference I've seen on the rear is 72 and up sometimes have a date code in larger black letters.

Both my cars have a 6500 redline tach. 70 Challenger RT SE 440 AT, build date 917. 70 cuda 340 4-speed, build date 310. I have about 4-5 more of those tachs, I will try to remember to take a look.

Some non-HP cars also came with rally dash (318 or 383-2). Maybe it would make more sense for those to have a lower redline?

My 71 440-6 Challenger tach is the same as yours.
After reading Pauls post and agreeing some early 72's used 8 grand tachs, I wonder if the 5500 redline 8G tach could in fact be from a 72 and not 70-71.
Since the 7 grand 72-74 tach has a redline of 5500, perhaps the same redline was used on the leftover 8G tach installed in rallye clusters in 1972 lower compression 340 E bodies.
Also agree with Barnabas

I have a 70-71 8K tach with redline at 6500.

I also have a 72-74 7K tach with redline at 5500.

#s on the back of each match yours.

clearly it's not a vendor/supplier issue because all the different tachs have the same vendor #.

The fact that these different tachs share the same part # tells me that the factory was only keeping track of one kind of tach. meaning that they probably did not care to differentiate between BB/SB or auto/manual trans or performance/plain jane, one part # = one tach and a car either got one or it didn't. If you ordered one over the counter you could end up with any one of them. It would seem then that each tach superceded the previous one. The 5500 redline 8K tach probably came between the other two making it late 71/early 72.

It wouldn't have come from a 74 360 four barrel car would it?

Sounds like we need to find all the 5500 redline 8K tachs we can and gather some more info.

Sounds like that car might give us some good info.
7K or 8K tach? redline at? SPD?

I was just looking for pics of tachs in dealership sales brochures. The 72 Challenger brochure printed in August of 71 shows a 70-71 dash with an 8K tach. unfortunately you can't see the redline due to the angle of the picture.

In the Illustrated Facts and Features Manuals (unknown print dates)...
The 71 Challenger manual shows a 70-71 dash with a 7K tach.
The 72 Challenger manual shows a different 70-71 dash with a 7K tach.
The 74 Challenger manuals picture is washed out and hard to see, but I think it's a 7K tach.

Only the 70 challenger and 70 barracuda manuals show 8K tachs, but interestingly they both have a different gauge face than what we're all used to seeing. Instead of the needle sweeping from lower right around to upper right, it sweeps from lower left around to lower right kind of like the speedometer.


All of that info may not mean much, but I think we should still be looking at the late 71/early 72 cars for more clues.

Looked at a bunch of '70-'71s since Sunday still haven't found a 5500 redline.
the 318-383 2bbl sounds possible?

I checked mine over the weekend. My R/T was built in March w/ a 440 Magnum. It has the redline @ 6500.

1970 Challenger Convertible soon to be T/A convertible

Contrary to the opinions of some, I am not dumber than I look.

I saw and spoke to owners of 2 Hemi Challengers in the big tent on the midway at the Mopar Nationals.
Both were 8 grand tachs and both were stated to be originals to the car. One was redlined at 5000 rpm and and the other at 6500

1971 Hemi Challenger owned by the same person for 30+ years, 605 built, dash never restored, had the 5500 RPM Redline 8 Grand tach.
Could it possibly be a late 71 change as production eased into 1972.
All 7 Grand tachs have a 5500 redline.

I have two:

71 440-6 Sep 70 build date - 6500 redline
71 340-4 May 71 build date - 5500 redline

Both cars have the original clusters.

I have an original untouched rallye dash setup in my 74 Challenger that I installed from a 383 automatic 71 Challenger R/T and it has the redline at 5500.

416 stroker from Nick at Compu-flow. 11.14 in full street trim. Seems like a new best every time out.
11.06 open headers----so far!!

All 7 Grand tachs have a 5500 redline.



Is 605 the # of cars built, or the build date? What is the build date?

We need to collect all the build dates we can find for cars with the 5500 redline.

I'm still thinking yes, late 71/early 72.

1971 Hemi Challenger owned by the same person for 30+ years, 605 built, dash never restored, had the 5500 RPM Redline 8 Grand tach.
Could it possibly be a late 71 change as production eased into 1972.
All 7 Grand tachs have a 5500 redline.



Terry are you sure on the SPD, because I always thought that late 71s switched to the 7k tach.

That's what my 71 Sixpack SPD 331 and the survivor triple black hemi Challenger both had.

Terry is sure about the June build date on the car that has the 5500-8000 tach. The car sits in my garage. Terry had phoned me about what I had in my cars. I have 4 E Bodies with Rallye Dashes. The Two Cudas are Nov. built and have the 6500-8000 Tach. The Challenger is Oct. built and has the 6500-8000 Tach. I had never really taken the time to look at the cars in detail like this. I run a tach drive Tach that is on the steering column in the June built car at present, so I never really see the Chrysler Tach. I think Terry might of taken a picture of my Dash at some time. Terry and I then went to the next big mopar shows looking at the dashes to see what tach was in June built cars. We also talked to Floyd that vends across from us because I knew he had a late built E Body also. If you read Floyds post that is a couple above this one he states that same thing as Mccannix does.

That's interesting. I have a super late built 71 V-Code Challenger with a 7k tac .....I always thought someone changed it. It was a drag car. I should pull it and check the dates...

I have a rallye gauge cluster with the rare 5500 rpm red line 8k tach.

It came out of an even more rare 1970 Barracuda convertible with a 6 cyl.

I don't know if it was original. I don't know if it ever worked. I didn't care. I paid $80 for the whole cluster.

Hook both of yours up to the same car and see if the 5500 registers higher than the other at the same rpm.

Here's a NOS one, that seems to have an unusual redline - 5000 on a 8K. What was this used in/for?

Terry,

The two I know for certain that were not messed with:

1: 70 440-4 4-speed 'Cuda - 6500-8000rpm
2: 71 383/auto Challenger R/T - Sept '70 build 6500-8000 rpm

I have (and have had) '72 clusters with the 8K tach - untouched as I parted out those cars. The other '72 cluster is in deep storage so I can't easily check it for you now.

Your theory of the low redline units slipping into late '71 model production makes sense based on what we're seeing here.

Interesting info.
I'll have to go check the redline on mine.
71 R/T Challenger with 383 4 speed, scheduled build date 6/16/71 which I assume is considered late.

I checked my cars last night:

JS23V Dec69 8k w/ 6.5k redline
JS23R B06 8k w/ 5k redline - looks like the NOS one above
JS29R0B12xxxx 8k w/ 6.5k redline
JS23V 723 8k w/ 6.5k redline

The set in my 71 Challenger 340 were 8k w/ 6.5 redline but they were not original to the car.

The red line on that one looks to be 6500. You can clearly see the color change from the Amber at 6500.

Contrary to the opinions of some, I am not dumber than I look.
