i have a 84 camaro and we put a 69 327 in there and its bored .40 over... it has a 4 core radiator and two 10'' fans running all the time.... it wants to heat up really fast.. i was wondering if i could just take the thermostate out and not put one back in...... or what else i could do to solve this problem....

Dont remove the thermostat

THERMOSTATS
Probably the most misunderstood components in the cooling system
the Thermostat has nothing to do with controlling maximum engine operating temps....especially when the rest of the cooling system in NOT efficient enough to handle the BTU'S the power plant is churning out in which case it will stay open while the temp gage continues to rise
What it does it do ? At cold start ,it blocks off the flow of the coolant out of the engine until the trapped coolant reaches the thermostat rated temp ...at witch point it opens and allows coolant to begin circulating
this aids in rabid warm up which REDUCES cylinder and piston ring wear by bring the engine up to operating temp quickly .
In short only the heat transfer efficiency of the radiator and the airflow
trough the radiator determine the engines maximum operating temp.
if you have a 180 degree thermostat and your engine is operating at 220 degrees changing to a 160 thermostat will not change your operating temps you will need more radiator or a more efficient one or more air flow or both .
If your lucky enough to have the efficiency of a good cooling system
a 180 state is a good choice .. why ?O.E.M testing has proven that the rate of cylinder bore and piston and ring wear is DOUBLE the wear rate at 160 degrees then that at 180 degrees .. also 160 doesn't get the old in the pan hot enough to boil off condensed moisture and blow by contaminants which remain in suspension and accelerate the formulation of acidic sludge in your engine

There are several reasons your may be running hot
but first to be sure check against gage readings with a I/R gun piont it at the thermostat housing and see if the gage reads the same.

then go from there .
