What would be the correct engine fan used on a 1970 chevelle ss no air 396 350hp car. Build date 02-23. was the fan a 4 blade or 7 blade fan? Fan clutch? Box 21 of the build sheet says I Z fan clutch. When did they use the 7 blade fan? Thanks.

For better cooling for my engine would a 7 blade be better than a 4 blade or would they be about the same? Thanks.
