67 BB heater hose clamps w/AC

[tim sargent]

I have a couple of questions about heater hose clamps for 67 BB with A/C. Is the large heater hose (3/4") that goes to the water pump fastened by a Corbin wire type clamp or a screw type clamp? If it is a wire type clamp is it red or gold in color?
Thank You

BB's with A/C use a zinc-color side-screw clamp on the 3/4" hose at the water pump fitting. Only one of the BB's I judged yesterday at Bloomington had the correct clamp at that location.

Thank you for this information, the judging manual is silent on this (at least the one I have) and I know LIC sells the screw type clamp for that application but the AIM seems to indicate the clamps are the same as production in the C60 section which would be the Corbin spring clamp.

The new 67 Judging manual states the side clamp on the water with AC cars.

Tim -

If you'll look in C60, Sheet D3, item #4 (clamp at 3/4" hose at water pump) is called out as 111608 or (optional) 9420906 clamp. Then if you go back to the base car section, UPC1Asm, sheet D7 (heater hoses), you'll see that the 3/4" hose uses only the 272852 clamp at all four locations; that's the clue that the 3/4" hose at the water pump on A/C cars uses a different clamp, and the illustration in C60/D3 shows it as a screw-type clamp, not a Corbin clamp.

The same screw-clamp usage at the water pump nipple applies to small-blocks with A/C, but it's not called out in the Judging Guide.
