I'm pulling A/C and parts from a 71 350 to install on my 1970 Cutlass Supreme Conv. 4 bbl. 350, which presently has no A/C. I've got everything except a fan. Guess I need a 6 blade, but not sure. Also is there a need for a fan clutch? Not sure what that gets me.
Can anyone tell me what fan to look for, and if anyone has one for sale?

Should I be thinking about upgrading the radiator as well?

 

Yep, you need the 6 blade fan and clutch for maximum airflow at idle. The clutch disengages at cruise speed so less load on the engine and less stress on the belt and fan blades.

Please make up a conversion thread, as others have inquired about this swap before. I would love to see it myself, as it does have some challenges.

 

thanks Rob. I'll look for a fan.
