I have a question about using a mechanical fan. I have a '70 C-10 with a 350, and would like to use a mechanical fan and clutch after the conversion. The 1970 C-10 has a 17" fan. I got the conversion parts a few months ago and am about ready to do the conversion, but the serpentine parts have a 19.5" diameter fan. Since the fan rotates the opposite direction from the non-serpentine system, I can't use my original fan. I'd like to use the 1970 fan shroud, so I'd like a 17" fan (only reverse direction from the original). Has anyone done this? Any recommended fan?
