160* thermostat - The 1947 - Present Chevrolet & GMC Truck Message Board Network

the cooler a motor runs the more gas it will use, and the less power it will produce..the intake needs to be hot to vaporize the fuel going to the pistons, a 180 would be better than a 160....but a 190 or 195 would be better than that...colder air going into the intake is good but once it goes into the intake it need to vaporize for a better burn. more power, more mileage..you may also need to change the rad. cap to like a 17 lb. cap...and add an over flow tank...i have always done this with good results....

Not to be a disagreeabe guy.. BUT, engines LOVE cold intake air... Cowl hoods on '70 Chevelles, Ram Air GTO's, Outside Air Induction(Olds 442), icing manifolds at the drag strip. NASCAR air intakes are at the base of their windshields.. high pressure/cooler air. All of my ol' hot rod cars, motorcycles, boats, have all run better at night 'specially if they can get a cold snort of dense night air. Engines need to run hot enough to cook the moisture and condensation out of the oil in the crank case but they like cool intake air. I think your 160 thermostat will be fine, it doesn't open 'til it gets to 160*.

i have always read that at 180-190 the enging clearances are at spec and with a no thermo or lothermo your runnig things with closer non optimum tolarances

i have mostly used in the 190 range for my old vehicles// and when i lived up north i liked having a hot heater
