83 Fan Question
I am starting to clean up the engine compartment in my 83 Dump. I noticed that the GM crate 350 in the bay has a three bladed fan. Is this correct, normal, or just strange?

Re: 83 Fan Question
My 305 has a 3-blade fan with a thermal clutch. Don't know if it's original or not, but previous owner didn't do much of anything to the truck.

Re: 83 Fan Question
I *THINK* 5-blade fans were used in trucks with AC and maybe with HD/tow packages.
My '87 crew w/o AC has a 3-blade fan.

Re: 83 Fan Question
Thanks for the replies!!!! No air in mine, but it has the heavy duty tow package.
