Hey guys,
Are GM fan clutches directional? I found one I like for my 250-nova, but it had the multi-groove pulley (which is run the opposite direction) This clutch was on a late 80's sbc with three blades.
Is a fan clutch with three blades enough for an almost stock 250 & power-glide trans, with no a/c? I will try install/make a fan shroud... If that is still is not enough I would just add small pusher fan on the front.
Is this all a good idea?
