Is there an upgrade to the lame stock speedo? 85mph?

Get a "Sharpie" .. add a 1 ...

Just get an older one. My speedo from '76 goes to 160!

The racing websites probably have aftermarket whiteface gauges too.

Yes you can get them re calibrated with a new face plate, I think it's about $200. Ron

PS but who goes 85 mph

Your speedo will not fit his cluster.

The aftermarket providers carry units for this swap.

You need an aftermarket speedo like this one from Corvette Clinic. Have one in my '78, but don't know if their still available. IMHO the graphics on the ones I've seen of late aren't quite as good, so I'd be picky if there's any choice left among them.

Does the speedo gear in the trans need to be changed as well?

Call John, he can reface and calibrate your speedo. Did mine and did a great job...

You can get a speedometer with higher numbers but the late 70's and 80's will only do 81 mph flat out. LOL

TheSkunkWorks

Does he also rework them into high MPH speedos?


my 76 ray, speak for yourself.

thanks guys that puts me on the right track. looks like redline is the way to go

Guess that depends on what you call high MPH. He put mine to 140 MPH. He used to do the 165 but said those are very cluttered with the numbers so close, and there was a calibration issue too. Since my car is a street car, I thought if I'm spending any time around 140, I'm probably in trouble anyway, and knowing about the additoinal 25MPH the 165 would show, isn't gonna help!!!

I need to get this done also and have seen other people also mention

Has anyone had experience with either one of these companies and is it $200 just for the speedometer refacing/recalibration?

talking about speed what will a stock 81 with an auto do for top speed?

larryg3

Really!!!!!! I have had mine over 80 a time or two. it is stock with the exception of 2.5" true dual exhaust and 3:54 rear diff.

And i do have a 140 MPH speedo from a 78 vette re calibrated and with the Speed sensor

FRANKENSTEIN4x42000

so this thing won't be quite as fast as my C6 i am guessing but it's ok i can't leave stock alone so i might have to work on that a little bit

Fast81

140 mph is more practical, 165 mph is a STATEMENT !!!!!!

i only got 165 cuz 140 was out of stock and i was impatient to get the dash back together

The easiest and cheapest way is to go to a swap meet and pick up a 78-79 speedo. I believe the 85 MPH ones were phased in for the 1980 and later models during the 1979 calendar production run.

I had a 1980 way back when and felt the same way- even though its illegal to go 85+, it looked bad. I was at Bloomington and easily found a '78--79 speedo and swapped it out for very little cost.
