First off what is the temerature the engine should be running for maximum ecomomy and preformance? Second, what if you could make your computer think it was running at this temp all the time? Would this mess up other sensors? If so which ones? Ive solved the problem about the cooling fans, i have a seperate adjustable thermostat, plus a switch in the dash, so cooling isnt a problem. Has anyone done this, or thought of it?

i dont know what the optimum temp is....i have a 160 degree stat with a 3 row rad. and wired the fan so that it stays on all the time....mine runs between 135-140 degrees no matter what...

Chevy SB's generally produce maximum power on the dyno @ 170F degrees.
Maximum fuel economy would come at a much higher temperature.

160 is way to cold, especially in winter. These cars run well from 175-195 degrees.
By the way, in the winter here...my 170 stat ran at 176degrees all the time.

Also, with colder motors (internally too), you are more prone to knock.

so is there a way i can make the computer think its running 170-175 all the time?

Mine is usually at 168 or so but if im driving stupid it will get up to about 180 or so
