That`s a lot of horses for a 10.5:1 engine. I`m running two different 502s using 454 radiators with no heating problems.
I have a 355 SB 12.0:1 that dinos 500+ with a griffin 4 core in a 69 camaro, with no heating problems.
190 is a normal operating temperature.
Griffin will make what ever you want.
And so will USA radiators
also custom builds radiators.
