Chain for modern Triple and 5 speed freewheel
What chain would work with a 5 speed Suntour freewheel and a 10 speed Campy Triple?

Replace your 5 speed Suntour with a 6 speed Suntour 6 Ultra-spaced freewheel, then run any 8 speed chain, or an old school SEDIS 6 speed narrow. You still might get some chain rub inside the front rings in some configurations.

Any chain marketed as 6/7/8 speed should work with that combination.

SRAM PC-58 or equivalent. I second the recommendation to replace the 5-speed with an ultra-6.

Why an ultra-6? Is it 120mm?

A Suntour Ultra-6 freewheel takes up only slightly more (a few millimeters ish as I recall) horizontal space than almost all 5 speed freewheels of any brand. This is because the spacing cog-center to cog-center of an Ultra is narrower than regular 5 speed freewheels (identical to Shimano HG-7 cassettes as it happens). This means you can typically swap it onto your rear hub without making any other changes to the rear hub or hub spacing of the frame.
Furthermore you can use high-quality and light 7 or 8 speed chains with excellent performance in a friction-shifting set-up, which will also work adequately with the typical 7/8/9/10 double or triple crankset. The 7/8 speed chains will perform nicer on the narrower Ultra-6 spaced cogs than on the regular, wider-spaced 5 speed cogs.

I guess the consensus is that it will work to use a Suntour 5 speed freewheel with a modern triple and that 7/8 speed chain would work best. I f I were to coldset the rear drops I would probably go all the way from 120mm to 130mm to use 8/9/10 speed freehubs.
