I used a late 90's 4.6 T-Bird fan before (On my Torana, way back when) even on the low speed (it had 2) it could sit in traffic in the middle of the summer all day long and never run warm

It was somewhat deep though, so not sure how fitment would go on different vehicles ?

I just went with a pair of high output Spal fans on it's new engine swap setup now though, see how they go. (no room for another Tbird one...too deep)


Here is an old pic when I was mocking it up...perfect fit on a 28" Summit radiator. (the fan blades were sharp hence I took it off while working with it )
