305 to 350, 305 radiator enough? - Third Generation F-Body Message Boards

Will my LG4's radiator cool my new 350 enough? I don't plan on exceeding 5500 RPM ever, so its not too high of a revver.

I did it with a 2 row aluminum LG4 radiator, and it doesn't go oner 185*. Your results may vary, so keep an eye on the temp guage.
