Anyone know what thread size the heater core fitting is on the block? I'm deleting the heater core and using the port to run my am lines to the turbo. I'm using the drain plug on the driver side of the block as a supply and the thread pitch on that is 1/4 bspt and I found -8 adapters for this. But now I'm stuck trying to find info on the heater core thread. Any info would be great.
Well i figured out the the thread pitch if anyone needs the info. The heater core hose end thread is 3/8" bspt not npts and the drain plug under the exhaust manifold is 1/4" bspt. Will post pics of my set up later.
welp since the op didnt respond, i bought a 1/4bspt fitting adapter and i will chime in to see if it works for the coolant tap under the exhaust manifold.

Hey what were your results? I bought a 1/4BSPT to 1/4NPT fitting. Then I bought a 1/4 NPT to -6an fitting.
