Also sold by vintage air as part 70654-V

I ordered the Vintage Air offset water necks from another retailer, what they delivered to me was in an Offenhauser box with the original part # covered. I was able to see under the sticker and guess what... this is the same water neck for half the price. I'm processing the return on the other company's parts now.

3.0

A near miss. The relief for the thermostat is far too deep.

I made a .060 thick aluminum ring to fit the relief in the housing to properly hold the thermostat in place. Without the ring the thermostat would rattle around and eventually destroy the housing and/or the surface on the aluminum head, plus it would by-pass more coolant than desired around the thermostat due to the poor fit. Externally they look great and fit well. It would be nice if also available for 1 3/4" hoses.

Exactly what I needed when I installed the vintage air air-conditioning bracket on my flathead. Hoses easily clear and don't interfere with anything else. The outlets are machined beautifully and look great

When installed on my Mercury the water neck did not hold the thermostat down. With coolant running through it the thermostat would rattle around in there. The relief for the edge of the thermostat was too deep.

Did an AC conversion on a 51 Ford F-1 and this was the neck to go with to make the project work. Craftsmanship is flawless.

Can this be used on 24 bolt edelbrock aluminum heads with the water neck on the front of the heads? I have these heads on my 1946 ford pickup with 2nd generation flathead v8. Thanks.

Where do I find the offset radiator hose to go with this item? I have seen before for sale a radiator hose set that included a special hose that bent around to fit onto this straight water neck. Where do I find these for sale?
