cooler thermostat?
I replaced the intake manifold on my truck with an aluminum Edelbrock manifold off my 77 Camaro. well, the engine gets real hot real quick and I was thinking I need to get a different thermostat. I saw that the thermos for our trucks are like 195 degrees. Wouldn't it be better if I went with a 180 degree unit instead, or maybe even a 160? Where could I get a 160 thermo?

You can pick up a lower temp thermostat at any part house.

If the rest of your cooling system is in good working order and you are not running wild compression, ignition retard, or very lean mixtures a 195 should be fine. Most new vehicles only come with 195 thermostats and will not run well if they have a different thermostat in them. I run a 195 all year round with no problem and it can very hot (100 degrees) here in the summer. A 180 will work fine for carburated vehicles but a 160 can actually cause your engine to run too cool.

I replaced my 160 (which had failed stuck open and my truck ran too cool) with a 180. So far it's great. Truck warms up fast, and I don't have to put up with waiting for an hour to get good performance out of it.
I'd go with 180. Good compromise.

I use a 160, I have 10:1 c.r. I had a '83 Bonneville once that ran at 220 and was the way it was designed. After 100,000 miles it ran like garbage and overheated. I dis-connected the computer, put in a 160 and it ran great.
