i know the post is 4 yrs old, but this 4 blade fan fixed blade does sound right for a 77 350 engine.

No those came with a 6 blade clutch fan. The difference is in the fan clutch one for heavy duty cooling and the other for standard cooling.

Ok, i just wanted to say my  former 79 blazer had a 4 blade fixed.  It was a 350.

I have a five blade fan with thermal clutch on a 84 c10 305/700r4.  Is that the correct fan blade?  It looks like it was made that way.
