Ok, I have an 89 rs that had a 2.8 in it, I am currently doing a motor swap to a 350 carb setup. My question is, will the oil pressure sending unit, tachometer and temp sensor be compatible with my gauges?? They are the stock v6 gauges. I went out and bought a new sending unit for the 350 and still need to get a temp sensor. Also, i have a stock HEI distributor on it too. Any help would be greatly appreciated.Thanks in advance

 

i am not sure so dont quote me on this but i think if they are mechanical the oil and voltsand water should work but i dont think the tranny will if u swap trannies. it will need a new speedo cable. i hope his is right. maybe others will chime in if i am wrong. if they dont work just buy some autometer gauges i knw they are more money but i would trust one of them over the stock gm crap they put in there. i have owned 4 cars in my life tempo s10 elcamino and a camaro and all except the tempo had bad fuel gauges and oil and volts. the only thing thats worth a damn is the speedo but even that was fudged up in the elcamino
