Radiator for '71 C10, 350

[57T210]

Hi Folks,

Newbie here...great site.

Just purchased the truck. Has a 2 core radiator left from previous Owner conversion from 6 cyl to 350 and no fan shroud.

My questions include:

- Recommended supplier for new radiator? Just checked out a couple of prices: ~$200 for a 3 core and ~$230 for a 4 core, both new.
- Go with 3 or 4 core? Truck will tow pretty fair sized trailer on occassion but otherwise, light workload.
- Fan shroud prices don't appear to vary much although open for suggestions from someone who's shopped.
- Additional hardware needed to convert radiator and add shroud?

Thanks for the input. Again, great site.

Regards.
