Where is the coolant going

You may want to contact SuperchargedSS, I think he can get OEM parts for a good price as well.

Google "castech heads" Hope I'm wrong.

nevermind - you have a puddle - i missed that.

Not sure if your NBS has the same intake manifold design my OBS does...but OBS are NOTORIOUS for intake gasket leaks.

If your overflow is leaking that much, you should see drip marks underneath it...at the very least where dust would normally be, there should be some drip marks there.

If not, I would personally start looking near the manifold and heads...

After a cold morning, get underneather your truck and follow the drips...there is most likely fluid collecting somewhere that you can trace back up to the source.
