Ok, Im sure some of you are familiar with my car, bought it from Mexicant, 90 240 w/a 93 twin cam swap. Im guessing I drive it more than he did, so he never ran into this issue. Anyway, the overflow was located too far below the top of the radiator, so we relocated it. I havent actually overheated since then, but did get pretty hot while sitting in traffic one day. My question is....having the twin cam swap, does this require a bigger radiator than what came in the car with the single cam? Just throwing some ideas around before I spend $$ on a better radiator only to find it doesn't resolve the issue.
