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.

my R coda 70 cuda has orig 6500 tach.

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

my SPD 05/26/71 440-6 is a 6500 redline - and while faded a bit is 6500 - tried posting a pic - but too big - off topic - but can anyone pm on how to resize pics - thanks in advance - Joe

Alright guys Dan and I found a 70 barracuda 383 2 barrel auto trans with its original rallye dash...

"ok heres the info on my tach.....yes its the same one it was born with lol
at 5k it is a yellowish color up to 6,500 rpm then its a redish orange up to 8k"

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

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

70 Hemicuda - Oct 69 build.

Left to right, top to bottom.
Tach - Stamping on back of tach.
Stamping on back of cluster housing - Stamping on back of clock.

70 440-6 Challenger - Build date unknown.

Left to right, top to bottom.
Tach - Stamping on back of tach.
Stamping on back of cluster housing - Stamping on back of clock.

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.

605 is June 5, 1971 build date

Someone was looking for this.

Looked at the Rallye Dashes I have
70 Challenger 383 auto....6500/8000
72 Cuda 340 auto..........5500/7000

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.

Well it looks like I get to spend my evening going through all my cars and all my extra gauge clusters
