Another Thermostat / Housing question.

I originally purchased this neck and this T-Stat for my SB. It came as a kit.

Mopar Performance P4286759: Chrome Thermostat Housing Fits All Slant Six, Small-Block, Big-Block & HEMI Engines 1978 & Prior | JEGS
Mr Gasket 4367: Hi-Flow Thermostat Chrysler, Dodge | JEGS

I drove the car twice and on the 2nd run the T-Stat wouldn't open. So I pulled it.

I then went and purchased this T-Stat for my SB.

The T-Stat sits fine in my Edelbrock Performer intake manifold.


Could be a tad wider but none the less it fits.

The problem I am having is the housing I now have has a has like a groove that isn't allowing the housing to push again the T stat and hold it in place.


When I put the T-stat down on top of the intake the T-stat moves around in there.

Now here is my question:

Will this housing (link below) work with the T-Stat I have? There is no pics of the under side of the housing for me to judge it. Just looking if anyone else has any experience with it.

In the end I just want a housing and 180 t-stat that works without spending $100 for a housing.

Thank you in advance.
