With all due respect, unless a mech fan is absolutely necessary for heavy-duty towing or bracket racing, you &or The Caretaker should use a pair of electrical fans.
Civilian LT1 Caprices, 2.93 Roadmasters, and Fleetwoods with 2.93 or 3.42 came with mech fans. Nearly every single one should have electrical fans instead.
Luckily, cars with less room underhood simply can't fit one, otherwise I'm sure someone would've tried, what with the people here who refuse to delete them.
As Brick B-Body already stated, the mech fan is worth -10 horse.
I cannot confirm that may also cost an MpG or 2.
Jus sayin …
