Technical SBC 350 Getting Hot on Highway

I have been considering that myself.

I cannot keep up with the Gish Gallop.

 

A little TMI there buddy...

 

Well after spending (wasting ) a half hour looking at a years worth of posts here, so what was his problem ?? Is he just chasing temperature numbers ? I've seen engines run hot with no cure and engines that run cold with no explanation. From the first posts he had a really horrible mount of two electric fans and a box shroud that totally blocked airflow through the radiator. I have a 69 Camaro that I purchased used in December 69-January 70 that had a 307 2bbl stock in it. Ran stone cold. From the start replaced that in early 1970 with a 66 Nova HP 327 with Rochester FI unit. Replaced radiator with a factory unit for a 396 HD. Factory radiator hoses with wire wound support and a factory low temp thermostat. NO AC and an automatic trans. Never got hot and stayed at about 180F Factory fan shroud and a silicone clutch factory fan. Did put on it a "burp tank" on the radiator. AC condenser installed wrong will always starve a radiator for air. Sustained high speed and advanced timing will heat up. It's quite possible the actual thermostat unit was not handling enough coolant flow at high speed or high demand. Not all thermostats flow the same amount. I have a 65 Ford PU with a 300ci and air conditioning. I did not build it that way, this is the way it was given to me. Clifford intake and exhaust. It always boiled over, yet my 64 with a transplanted 300 runs so cold the radiator cap is at half twist. Just setting there ventilated. On the 65 I replaced the thermostat with a 180 racing unit, tossed the air conditioning and adjusted the timing. Now it runs OK. Go Figure.

 

Does it have a miss match of Vortec parts? You may need a bypass hose. A vortec Block does no have the second hole on the right side water pump mount so coolant only speculates in the engine when the thermostat is open without a bypass hose

 

came and checked on this thread....looks like nothing has changed.... it's still the more popular you are with the secret hand shake group of GOBS,... the more right you are...although I have no cars that run hot, I have bought them that did,... and although it's been proven coolant running through the rad too fast ,doesn't give it time to cool,..puller fans and shrouds cause more problems than they fix..., it the same ol thing... if you get a bigger group of wrongs.... they can run off the rights...
