You guys know whether any 442's came with a 5 blade fan? I always thought they had 6 blades. Mine has a 5 but the engine is not original. I'm thinking of swapping to 6 blade anyway for better cooling but wanted to check on some history first...

Thanks

 

They either came with a 4-blade or a 6-blade in '68.

 

Thanks. Was the difference AC or not?

 

I'm not certain for '68, but generally either A/C (C60) or Heavy Duty Cooling (Y72) got you the 6-blade fan, thermal fan clutch, and a shroud.
