Good morning, everyone. I just bought a 1983 oldsmobile cutlass supreme with a 5.0l 307 engine. I need a fan blade, but don't know the exact size or number of blades. Any information would be appreciated.

5 blade. Looks uneven when you look at it. Not at home right now but when I do get home I’ll look up the part number

I've gotten rid of the OEM blades, run these 19" 6 blades and Hayden SD clutch on clutch setup or solid hub version. I find they move more air when engaged and allow more air to pass through them when windmilling while cruising at speeds, downside, they're little louder than stock blades

Do have a 97 C3500HD with 20" version with Hayden fan clutch.

Ran both standard and reverse rotation versions.
Word of caution..make sure your body mounts and engine mounts are good or you'll flex everything and chew up the shroud

Stock stuff is just fine for a 307. 19" nominal size. Made by a company called "Brookside".

Part number for the fan is right on the blades. 22511036. Note the brookside stamping at the top.
