You've changed everything else, consider an electric cooling pump?

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?

That was my first thought too but then I checked his mod list. I think the 35 gpm pump with a backing plate he listed on the mods is exactly that per https://www.cvfracing.com/ford-351c-...-35-gpm-black/ But it would be worth checking it's correctly wired and plumbed and sending water in the correct direction and that none of the radiator hoses are collapsing at high pump revs.

Regards Blue
