Hate my mechanical, stupid clutch on it has gone bad 3 times in 2 years and would just like to get rid of it. Most of the aftermarket ones don't really seem that impressive in CFM compared to what some stock units will do and I'm cheap so I'd like to swap one in from a junkyard.

So I need something very slimline and powerful, any suggestions? I believe it has to be under 4" deep even with the waterpump studs trimmed down.

Mid 80's GM cars. Try about an 86 Olds,Buik or Chevy car, Thats what I run.
