360 engine

there is no vacuum advance on my distributor! do you mean read it on the ABodies site (spoiler,black air dam) I am still not sure what your saying about valance? I should probably hook up a trans temp gauge when I do the cooler? here is pic of fan and radiator, will any 7 blade work and will a magnum 360 clutch fan work or does it have to be from an LA360
