Any one running without a thermostat? And are there any good bad sides to it?

 

Nothing but problems without a stat. Read some of the posts and you will get the drift. Basically the engine will never reach it's thermal range in order for the ECM to properly manage the engine and it's emission controls. Fuel economy will suffer as well as driveability. Use a 195 deg. stat and keep the cooling system in good condition and it will run it's best.

 

its not great w/o a stat but it is ok. it does take a while to warm up but it does. i know because i just took mine out. BTW i run a carb and i do plan on running a stat soon i just need to get a few things done first.

 

Thanks guys, i just had a 305 put in my car by a guy that works for a chevy dealer and he didn't do alot of ****... Like connect all the vacum lines, alot of gound wires, didn't put a thermo in, the list gose on...
