I've not fired my engine yet.i have a 160� stat that the mopar guy at the local speed shop sold me but since then I've read information suggesting a 190� would be better. Street car 440 ,040 over Cast iron closed chamber heads Port and polished 2.14/1.81 valves Harland Sharpe roller rockers Eddy RPM intake Holley 770 Street Avenger Comp cams XE274 cam 1 7/8 TTi headers 2.5" exhaust with turbo mufflers to rear bumper 26" aluminum radiator Viscous fan A/C Auto trans 3.91 sure grip Thanks! I’m listening.

Either the 160 or a 180 max... the higher stats are more for emissions reasons

I have soon a little searching and from what I'm reading here on moparts, there's quite a bit of differing opinion on what works best. I guess I'll reinstall the 160 and run my engine in and see at what temp my engine likes to live. If it doesn't want to come up to the 190 range I'll change it out to 180 so that it will heat quicker and run closer to ideal. I’m listening.
