I just removed the 130mph speedo/dummy light cluster on my 1977 camaro for the 150mph/tach/gauge cluster, i went ahead & replaced the printed circuit & read up on this forum about what it takes to do the swap. The problem im having now is the temp gauge goes to the red after just a couple minutes of running??? Im scratching my head now, is there something im missing?

I have to opposite condition. All my 71 Z28 gauges were restored by Gaugemarks, beautiful workmanship. But I must have the wrong ohm rating water temp sender as at 178 degree F my water temperature gauge barely moves from it's cold 100 degree resting position, maybe an 1/8". The sender I have is a single spade and is smaller in thread/diameter than the OEM (5/8") as I am using Dart SHP aluminum heads and the water temp sender is screwed into the driver side head. At 64 degrees F I read 3,333 ohms and at 178 degree F I read 221 ohms. Any help would be greatly appreciated.

I did the gauge swap a while back. The temp sender I used was rom O'Reilly Auto Parts. Product Line: BWD Part # WT359. I received this information from another member. Hope this helps.
