I’m leaning towards no thermostat. Still a ways off before I see how it all works out.
Good thread.

misterp266, You can still have the "By-Pass" function from the intake water cross-over to the Moon Cover.
The Moon Cover, as you know, has two "flat ears" that seal to the block surface.
I use a Meziere 55 gallon/Hr radiator mounted electric water pump that has two water outlets on the pump.
I plumb one water pump nipple to the Passenger side ear on the Moon Cover.
I plumb the second water pump nipple to the Drivers side ear on the Moon Cover. That Drivers side ear has a "Y" before the ear. The lower leg of the "Y"
gets water from the second nipple on the Electric Water Pump.
The upper leg of the "Y" gets water from the water passage that would normally mate to the factory timing cover with a "O" ring seal.
I run a thermostat with two 1/8" holes drilled into the stat to bleed TRAPPED AIR that may be in the cross-over. The thermostat works like normal.
Before the engine warms up the "By-Pass Leg on the drivers side does exactly the same job as stock but with a slightly different plumbing. Same for after the Thermostat opens. I run a 180 stat as I live in Michigan.
I love the Moon Part and the Meziere Pump. I did not come up with this By-pass design. A friend years ago showed the Mod to me. Non Pontiac guys think it is stock, LOL! And it clears a Cog Belt driven supercharger belt.
I don't run cog belt Vortech Superchargers.
Hope this helps.
