Hi everyone,
I have Non clutch 7 blade fan and 7 and 5 clutch driving fans, I guess original fan for 455 with AC was 5 blade clutch drive fans, now my question is witch system is better for 455 stage 1 engines, Original 5 blade or non clutch 7 blades? I want to use 160 degree thermostat and my radiator is new but it is copper radiator.
