1961-1963 ALUMINUM WATERNECK Tri-power Engine Performance I have a new set

I have a new set of blackened screws and washers you can add to the rebuild kit at a savings or buy separately on the page

We start with an excellent used early Pontiac airhorn and have machined (and installed)

You do not have to remove the 66 choke shaft

The "small" bases also fit all three carbs in the 57 and 58 Tri-power

Very easy to set the float
