I couldn't be happier with the cooling system in my hot rod. It's a 468-in, 13 to 1 Hemi, and a drag week 2018 we were in South Carolina and Georgia. It must have been about a hundred degrees in the Sun, and sitting in traffic for extended periods the highest it ever got was about 185. I think that the key is to have lots of radiator, lots of water flow, and lots of air flow. The car has a big aluminum radiator, 55 GPM messier pump, and a single dorman electric fan that was made for a Chevy HHR that I got for about 50 bucks at RockAuto. I ripped the shroud off of it and run it with no shroud.
Its got the radiator mounted water pump and I built a reverse cooling system by running a pair of - 12 lines from the outlet of the pump into the heads. Then from the block, a pair of - 20 lines into the top of the radiator.
