1970 speedo issue

Hello, as a newbie to this forum, Im in a pickle with my newly aquired camaro.. the speedo is not reading correctly, and before i do anything else.. Im wondering why the speedo needle sits at 6 oclock..? way off the 0.mph mark..?? it moves up when driving but the speed is out of wack...!

Does the needle need to be forced moved to 'o'mph..?

I cannot see a needle 'stop' anywhere on this gauge..

has anyone had similar issues..?

thanks den ( from Aus )

Re: 1970 speedo issue

Yeah, somethings wrong. It should rest naturally at zero. Maybe just the needle came off sometime in the past and it was reinstalled wrong. Pretty sure I read that at 1000 rpm it should read 60MPH that this is a standard for GM speedos. You could use a strobe app and set a drill to this speed to test. Hook up a speedo cable and drive the cable with the drill.

Re: 1970 speedo issue

I have also heard that it is possible to damage a speedo this way by trying to roll the miles back with a drill. Hope thatís not true in your case

So far on my camaro, I have repaired window washer pump, installed reservoir/tubes.. fixed indicator & high beam lamp, connected reverse lights, fixed passenger window winder mechanism, installed standard front coils, put air shocks on rear, will install new front seat retractable ADR belts, changed front headlights.... All to get Aussie RWC.
Love my USA Camaro.!
