225 running a bit warm!!!

A lower temp thermostat usually causes the vehicle to run hotter. A higher temp thermostat will lower engine temps.

When lower temp is used the coolant in the radiator doesn't have enough time to cool down. When a higher temp is used the radiator gets cooler thereby lowering your engine temp.

uhhh, not sure where your at, but down here in Texas a lower degree thermostat most definitely reduces the operating temperature. If your cooling system is up to par, the radiator has plenty of time to cool off between cycles when using a lower thermostat.

FYI One of the most common GM EFI tricks is to run a lower thermostat to keep the engine running cooler so that the computer can run a more aggressive timing curve.
