hi i put my msd system in with the colder plug and while i was at it i put a 180 thermostat in and now my truck runs real cold like around 120 or so i don't even have to use my fans while driving it the only way i an get it to heat up is letting it idle for 15 min then it gets up to temp. but when i take it down the road again the temp just drops right back down. i was told to advance my timeing a bit to get it to run a little warmer. just wondering what you guys think of this.
