Proper Water Temp For 350?
I thought my temp might be a bit high so I bought and installed an aftermarket gauge.
I have a 180 thermostat in it now. I went to the part store and the recommended one is 195. Is that correct? Anyway just driving around today its about 80 to 85 deg outside and the gauge reads 185. Turn on the A/C and run it about 70 mph slightly uphill for about 5 miles and it reads 200. Also I have a new 16lb cap. sound ok? What is the upper limit of normal? Would 210 be ok? Thanks Eric |

Like Mr Sothpa said, some ppl will say otherwise, and I'm one of them.
I have found better performance and gas mileage by installing a 160 degree thermostat. I have also found alot les vapor lock and that seems to be a problem in these trucks. Every one I have dealt with suffers from the boiling fuel. ------------------ '69 G.M.C. 350/350. Trying to clean up the left over damage from the Dope-Smokin-Old-Man I've been dubbed the Longhorn Freak/Fanatic/Expert, I just hope I can live up to it. FINALLY got the HORNIAC...a '70 one ton Longhorn with a Pontiac 350/350 and lots of 'personality'. Check out The Longhorn Webite.

good idea longhornmail, i'll try that to solve my vaporlock along with insulating the line.
I'll probably chang it back to 195 for winter though.
