Help Me Cool Down

Mine cools better w/ a mech. fan than w/ a clutch type. I have mine working pretty good now , 192-205 in the heat . I am going to try a 1" bigger alum. fan on the new jaguar (short) clutch that I pulled off tho , have to cut out the shroud a hair , when I get around to it , just because of the perf. part of it .
No way mine will idle down to 650 either .
I would over drive the pump if I could come up w/ a suitable pulley , like YR said ----

I always liked the mechanical fan myself. . I just put a clutch fan on the brown Duster because I have several and I have to use them on something. Clutch fans work good. but do fail. I once was in NY late in the evening wit a 69 dart with air. I kicked it into passing gear and the fan took out the radiator shroud and belts. I wasn't finding parts to get home . over a $500 tow bill. That was my last time I trusted a clutch fan for me. They are good for anyone else in my eye's. I like the factory 7 blade fans. I gave one to Dave for his big block Valiant. After market aluminum and fiberglass fans are good, They were good for taking out hoods and radiators. I would buy the cars cheap then. Probably still have parts from some of those cars. LOL
