I don't like that. The water going in is VERY cold and that's not good, especially for break in. As cheap as radiators are, I would get one for like a Chevy truck and run with it. And yes, that's a VERY old school grind, but it's a dang good one. You could actually go racing with it. It's just decent enough for that and would be extremely reliable, because of the low lift and single spring requirement. There's a lot to be said for old school technology. Even today.
