recently I changed from tpi to carburator on my 85 trans am. It was a 305 but now it is a 350 4-bolt main. I changed distributors and fuel pump. The other day I was going down the road and all the gauges quit working except the speed odimter. My question is why did the other gauges quit working, and how do I fix them? Is their any other things that need to be changed out or fixed. Thanks

 

There is prolly a relay or fuse that went out somewhere. The speedo is still working because it's cable driven, not electrical. I dunno where the fuse is though...sorry.
