That's a dual 1" unit. I suffered from my personal car running hot for years. I tried everything including a 2 row 1" aluminum radiator. It helped but only delayed the steadily rising temps. Then I switched to a dual 1 1/4" aluminum radiator without changing anything else and problem went away. This was before Cold Case even existed. That being said, at 200 degrees, you really don't have a problem. At 3500 rpm and 75 mph, i'm sure that temperature bump is felt in the cabin and combined with the engine noise, may be a little annoying. However, It's only an 'overheating' problem if 200 becomes 210 and then 210 becomes 220 etc.
