C-2 Dash cluster identification

[kobi67]

I have the cluster out of my car and see the date stamp and paper tag. The tag lists #'s for the components. Any way to cross these #'s to what the cluster has in it? Thanks, Kurt

 

[JohnZ]

I don't have those cross-references, and I'm not aware of any publication or site that has them; I'm sure the cluster rebuilders all have them, though. Try jason@corvetteinstruments.com - he may be able to help you.

JohnZ, Thanks, Kurt

LB.....LA........or LC stamp

There is a stamp on the back of the cluster.

LA is for 250/300hp tach with 5000 redline
LB is for a 365/375/425 hp redline of 6500
LC is 350 hp with the 5500 redline

Many times people changed the tach for bogus engine upgrades, but never knew about the above L series tags. I have seen Bloomington Gold judges check this in judging for such an upgrade....like a 365hp air car that started life as a 300hp.

80 lb. oil gauge on all solid lifter motors. 60 lb. on others

WOW... Thanks for the info. This is what I needed. Mine Says LC and has the 6000 redline (5500 Yellow line). The car is an L-79 car. That matches.. I can sleep better tonight... Thank you... Kurt

Jim,

I don't know anything about those codes, but my original '67-435 6,500rpm has LB on it.

 

[Ken Anderson]

Maybe it was a real low HP 427?????? Although, it should have #6412223 on the tag for a 6500RL tach.

This 435 shows LB.

 

[Ken Anderson]

See. I was right about the tach and it's obvious this is an original high HP cluster. Those judges don't always know as much as they think they do, do they? By the way, that is also the correct part # for a standard speedometer.

 

[vettefinderjim]

La.........lb??

My records show LA was 365hp solid lifter. Makes sense thought that it is 250/300hp
LB for solid lifter., yea

LC is definately L-79 and L-36. This sequence came after the 65 L-79 engine was introduced. Very early 65 L-79 engines used 300hp, "LA" tagged clusters.

Here's my original/dated "LA" cluster and tag ('67 327/300hp):

 

[Ken Anderson]

So, what's it all mean?

 

[JohnZ]

I think what it says is that the "LA" broadcast code was the base cluster assembly, with any other codes identifying other combinations driven by engines (tach redlines, 60# vs. 80# oil pressure gauges), and U15 speed warning.

 

[kobi67]

I contacted Corvette Instrument Service, they say the tach #'s are 2222=5500RPM, 2522=6000RPM and 2223=6500RPM. The cluster part# changed for tach. He also thought the LA,LC and LB may have been a shift code where they were manufactured. My date stamp has a 001 after it, I would have thought that was the shift code?? I sure would have thought the LA,LB and LC would have been an easy I.D. for the assembly line worker to pick the right cluster?? Kurt

 

[Ken Anderson]

You're getting closer.

ahh, John, I noticed the condition of the rubber washer above your cluster's tag is ahh errr not quite in "as delivered" condition, I am shocked, shocked . . . .

I understand your dismay :ugh ; that's as it looked when I removed it from the car; however, here's what it looks like now after restoration (saved the broadcast label, date stamp, and tach cable stamp)

We never doubted you, John.

MAN, he's good, isn't he? just when I finally thought we had caught him with something less than 100% beautiful, it turns out to be his "before" photo!

Again another true craftsman,I constantly say it that the details of a cars rebuild is what seperates a good car from a SPECTACULAR car, this dash cluster is something that no one will even see, but the time and effort that went into it to make it look perfect was still invested, Great job John I had studied the photos of your Grand sport and was in awe of it. (My son has one hanging in his room)

You really set the bar high for other to follow.

Just dont look so close at my 62 when we meet at carlilse
