Overheating small block chevy
I have a 1966 Chevy pick up that I have rebuilt. I’m having an issue with towing a vintage travel trailer (24ft)up a steep grade. It has a completely rebuilt small block Chevy 350: HEI distributor set at 38 advanced without vacuum, 180 degree thermostat, sniper efi, auxiliary fan, transmission cooler and mechanical fan with shroud. It tows great but will get into the 230’s within a two mile steep incline. I’m wondering what I’m missing. It will tow fine on straight stretches. Any ideas would be appreciated! Pictures attached.
