which coolant is the best? i have a 302 bored .040 and i'm going to need to keep it extra cool to prevent overheating on the street. i was thinking about the purple ice from royal purple. anything better? i know this isn't a very interesting question but it will save me a headache or two. thanks guys.

Don't know if any coolant is better than the next, but I've heard alot of good stuff about "water wetter" additive. You can order it from Summit. Supposedly it will make it run something like 30 degrees cooler.

when they say 30 degrees cooler they mean when added to plain watter, not a good idea is you don't want to rust the system. I would try some of the DEX-cool and maybe some water wetter. just make sure that your radiator and fan are up to par

What kind of heads, radiator, waterpump, etc are you using?
