I have my 69 firebird built to around 400 hp with aluminum heads and intake. Runs on 93 octane. I have an aluminum radiator (3 core) with 16" electric fan (1700 cfm). Stock water pump. 180 degree thermostat. Ran hotter w/o thermostat. On the highway, it runs 200-210 degrees. In town, it will get up to 220-230. At 225, coolant will run out the overflow tank. I was thinking of upgrading to 3000 cfm fan first, then if that didnt work, maybe a better radiator.
HELP!
