The Ford Barn - View Single Post - Engine temp rises when I get to cruise speed

Something that I'd try is to remove the shroud (as it would only help at idle or slow speed) and see what happens. This would be a pretty simple test and might provide you with some additional data points.

My 32 Cabriolet does not have a shroud - it has a stock (recored) radiator, stock fan in stock location, etc.. The engine has been bored to 3 5/16 and total CI is 284. The block was NOS (so no crud buildup). The engine can sit in traffic and not get hot (even on 90 degree days) and it always cools well going down the road (have been up to 75+ a few times).

I'd check the AFR first, re-jet the carb to get the cruise setting down a bit, then see what you get. Then (regardless of the AFR), I'd pull the shroud off and see what happens at both idle/slow speed and higher speed cruise.

Best of luck!
