145 mph speedometer?
I have a Standard 88 Camaro with the 115 mph speedometer. Would a 145 mph from a z-28 work in my car? Would i be better off just getting aftermarket guages?

Re: 145 mph speedometer?
I replaced the 85 mph speedo in my '85 with a 145 unit with no problems . I got really tired of pegging the needle against the reset button. There are usually a few 145's on E-bay at any time. you can get the whole cluster or just the speedo. Good luck.

Re: 145 mph speedometer?
To avoid any electric problems with the cluster, I'd suggest swapping in the speedo head only.

Hey, Hank,
Maybe hit that button an extra time or two (I hate when that happens)

Re: 145 mph speedometer?
I swapped mine a couple of years ago and can't find the details. I reaslly don't remember what I paid. I only remember that it was worth it.

Re: 145 mph speedometer?
Did you need to change the speedometer gear drive in the transmission? Found one on ebay for 95.00 does that sound familiar? Its brand new though

Re: 145 mph speedometer?
I did not have to change the trans gear. That would only have to be done if you were changing the rear gear. (once again I was too quick on the send button, My bad)

Re: 145 mph speedometer?
that's quite a jump from 2.73 to 3.73. Sorry, but I'm not familiar with auto trans driven gear colors or teeth numbers.

Re: 145 mph speedometer?
Thanks for the info. The car is a real dog until it hits 3000 rpms but then it only has 1500 more before it has no power.

Re: 145 mph speedometer?
Be aware that 87 and later cable driven speedos have a speed sensor that the earlier ones do not. Also the odometer reset buttons are in a different place.

Re: 145 mph speedometer?
I converted the car to a Carb setup and took out the computer. So the speed sensor shouldnt be needed. Thanks for the info.
