I want to drill and tap/weld AN fittings on these housings. Can these barbs be removed from 1) mixing manifold & 2) thermostat housing? They dont look like theyre cast into the main housing so im hoping a good tug with some vise grips will do the trick?
Important Notes:
-These fittings flow equally in both directions and can be installed either way.
-The higher the operating pressure, the more difficult it becomes to connect and disconnect the coupler.
-Due to the dry break coupler design, there will be some inherent flow restriction (pressure drop).
-Naturally there may be a drop or two when engaging and disengaging. -Do not disconnect fittings while pumps are running.
Potentially silly question: since you're already committed to doing some serious work on the cooling system, any reason you're not doing a rear-thermostat reroute and just eliminating the front housing altogether?

Because imo every reroute I've seen looks like s**t with hoses cobbled together and improper bends, etc. I may go with a reroute as the engine is out all winter but it will be a "custom" setup with tig welded aluminum piping
AN into the WP inlet manifold is easy with a Summit (or similar) NPT to AN6. Notice that the 180 degree hose end is "modified" (actually the effin thing is a biznatch to tighten without bending that hose end).
I believe that if done properly, the reroute can look decent. I used the stock '91 WP inlet hose to accomplish the 1st 90 degree bend off of the back of the head. It has a really nice angle upwards when mounted this way that points directly at the barb on my Supermiata crossflow (straight shot). Prior to the crossflow, I grabbed a nice S off of the local parts store hose wall and had a really clean look to the stock radiator.
Just look at #4 of a few stock block/head motors and you will see why reroute is money.
EDIT: the last pic is the hose I used for the stock radiator. The 90 degree bend isn't the inlet hose, it is the metal inlet pipe that mounts to the frame.

I have the same rad. Didnt realize how straight of a shot that is...thanks for the picture. I think I could fit a straight piece of aluminum pipe in there. then i could source water from the back of the head for ultimate cleanliness
