That could be, but you need to make sure the air isn't going around the radiator. Just cruising down the highway a stock radiator should be adequate.
72 olds 350 30over 9.5to1 comp cam 7a heads switched to adjustable rocker arms around 375hp
A new rad sounds like a good investment and probably necessary with higher compression. You want a minimum 2 core with 1" tubes for a replacement.
Just ordered a 3 core radiator from radiator Express supports 800hp hopefully direct replacement
Hopefully it cools better than the Champion 3 core did for my 403 in my 88. It depends on fins per inch etc. That 800 hp rating is wildly optimistic. A large 2 core will out cool a 3 core and usually a 4 core. Another thing that helped my car is the GN rad surround flaps. They basically make the air go through the rad, not around.
Dp you think a 2 core with 1 1/4 tubes would be best and where did you get your radiator surround flaps?
Aluminum 3 and 4 core are not as effective as a 2 core. The only way aluminum is able to cool better is when the tubes are 1" wide.
