mag thermostat housing?

True, I seen them at Summit pretty reasonable.

Initial plan was to use the Moroso adapter that is already on the truck on the LD4B intake, which with the smaller thermostat housing will not work, and Moroso does not sell the smaller one that I can find.

I could drill and tap the intake like I did on my LD-340 that is in my duster.

Thinking clear out of the box, drill and tap the timing cover for a fitting or a weld in bung? Might restrict flow to the heads too much.
