Re: Running a cooler 351 clevo
That would definitely tell whether the thermostat is inhibiting flow.
In the middle of winter (at least in country Vic!!) your engine will take ages to heat up properly with no thermostat. In snowy countries a thermostat is a must, otherwise your engine will wear out from running it so cold.
A thermostat is actually designed to hold water in the engine longer, not the radiator. This allows the water to heat up in the block, not really cool down in the radiator. Once at operating temp, it lets the out water out and cool water in.
krusty, have you seen the BIG free flowing thermostats you can get? The water passage in them is huge compared to those crappy stock ones.
