Adjustable electric fan thermostat question ?

I had two fans mounted on my hot rod radiator. One set to turn on at 180 and the other turned on at 195 (if it ever got that hot) with separate relays and adjustable reostats. With two fans there's always a back up if one fails.
Sound good , im a firm believer in redundancy and overkill. I have 2 fans also and will use. Ur rheostst ideia. I have. 2 fuel pumps, an ac condensor for a trans cooler, deep trans pan, biggest radiator i could cram in, hi vol water pump, small seperate fuel tank FOR Reserve, to keep full of race fuel and potassium for the purple flame thrower, overkill on wire gsuge size etc. I plan on some long road trips and dont want to be at the mercy of a rip off artists

In the trunk i will keep a distributor, plugs, carb, beltz, coolant, oil, alternator, jack with stands, tools etc. I take my Boy Scout Motto seriously to "Be Prepared"
