Thank you guys, I meant its 327 with a 350 turbo trans hehehe sorry. I`m used to Jap cars and building them so this is all new to me but very similar. I read that the temp on the 1963 with a 327 should be between 190 and 205. I replaced the waterneck and brand new radiator hoses and the coolant, upon taking off the neck I noticed there was no thermostat so I purchased one that kicks in at 195. Am I wrong on this one? Should it be a 180 thermo?
