Got some issues after trying to finish up my build. Here's what i got so far:

I just finished up building a 350 for my firebird with an LT1 intake conversion.

The LT1 intake on the car required me to have a remote Thermostat housing in order to run the coolant as a standard smallblock 350. On the intake i drilled coolant ports at the back of the head and i run one 0.75" hose from each side to the thermostat housing and then one big hose from the t-stat to the top of the radiator.

However, when i start the car and let it run for a bit, i hear boiling somewhere from the back of the engine bay but the therm is not open. (this is maybe after just a min or so of running at about 1500 RPM) there is also pressure on the radiator cap, which makes no sense becuase the thermostat is still closed.

This is a diagram of how i have it set up:

Could it be that my whole problem just air that's trapped in the engine from building it? What's the deal with the boiling sound, and why is the radiator pressurized almost instantly even though the thermostat is closed? Any help would be great, i'm really anxious to get this car back on the street.

Thanks,

Yea,it could be air in the system.

Is there a way that u can dump coolant directly into the remote thermo. housing and allow it to fill the motor seperate from the radiator? If u can,that would really help out b/c it happend when I put the new motor in my car several months ago.

i'll certainly give it a shot, just a few hoses to disconnect to get it directly in there...any other ideas?
