I plumbed in a pressure switch into the oil filter mount. The switch turns on if the oil pressure drops to 18 psi. I mounted a large red light in the car so that if I ever have an oil pressure issue the light turns on. This way I don't have to monitor the oil pressure gauge.
Also, I installed an AEM wide band gauge to get real time feedback on the air fuel ratio.
Yea that is the original AM Delco radio and factory Tach. Some day I might go FM.....
I replaced the factory cluster gauges with autometer (originals didn't have any numbers)
