Thermostat Housing ??

[Bertscova]

any one now where i can get a water neck like this ( http://www.summitracing.com/parts/PLR-9556/?image=large ) with a npt port on it i need it to be 3/8-18 but can use an adapter for the 1/2-18. I have searched high and low for something like this. I'm thinkin im just goin to buy this one and have a 3/8-18 port welded into it.

yeah i think you may have to go that route.

Out of curiousity, why do you want a 3/8-18 port on the water neck?

[evil_motors]

my guess.. aftermarket gauge

Wouldn't you want an aftermarket gauge tap'd into the intake or head for better readings?

[evil_motors]

well i know alot of people who do it this way because it is way easier. plus it is close enough to the temp of the engine. i also know people who monitor the hot side and cold side.. so no tellin what the OP wants

Personally, I wouldn't call the back of the thermostat the cold side, its more like the delayed side. Another thought is that there will be a plug on one of the heads that can be removed and a sensor installed there.
