1963 Tachometer with buzzer

[Jeff C.]

When I removed the dash I thought I would find the above tach. The car is a Mid Nov build with a numbers matching 340 HP engine red line 6500. The cluster is dated Oct 17 1962. The 63/64 judging manual says nothing about a buzzing tach but should this car have a buzzing tach?
Thanks,
Jeff

When I posted this I found the answer in "similar posts". It is a buzzer tach but 340HP did not have the actual buzzer.

Jeff,

That would be incorrect. My Dec. '62 340HP has the buzzer tach and the buzzer.

Had an all black 340 HP with the buzzer tach & buzzer. It actually did work.

Obviously not as smart as you Stu, we need a buzzer to remind us to...........SHIFT!

Re: 1963 Tachometer with buzzer

Nolan Adam's book has a good survey on the early production buzzer system on both 340 and 360 HP engines. Some had both the buzzer tach and buzzer, and some of them actually worked! Some had a buzzer tach, but no buzzer, and maybe even some had the buzzer, but no buzzer tach.

It appears that the buzzer system was cancelled about the start of production or shortly thereafter, but the parts disposition was likely "used until exhausted", which resulted in the above hodge podge of installed parts.

The '63 sales literature said that only the 360 HP FI engine had the buzzer system, so I never worried about it, but, clearly, Nolan's survey shows that it was also installed, hit-and-miss, on early 340 HP engines, .

It wasn't until I bought and read Nolan's book that I realized some early production 340 HP '63s also had the system - or part of it - but my SWC is mid-production, and by that time the buzzer system parts were long gone from production.

Re: 1963 Tachometer with buzzer

During restore of my '63 validated the tach buzzer worked however interestingly enough have never heard the buzzer go off while ripping through the gears. Must be a defective circuit in the tach keeping the buzzer from going off.

Re: 1963 Tachometer with buzzer

My buzzer used to go off at 6500 RPM's I was running factory 4:56 gears, so it was easy to get there. Don't really know if they were pre-set for a certain RPM.
