Looking to ID a factory three dueces manifold I bought years ago as a 1959 but doesn't fit, may be 57 or 58. Looks like cast aluminum- factory part number 540510 B-4-1. Any help?

Thanks to all who replied, Jon I see from your list that the manifold is probably a 1'61 super-duty. I have a Pontiac collector that is interested in the manifold and I don't see another "goat" in my future. Does anyone have any idea what this thing is worth (range would be fine). Thanks again. Lon

The easiest way to value something no rarer than this item would be to watch Ebay completed auctions. Take 3 items which sold, average the selling prices. Take this figure and multiply by 0.8 to obtain a rough wholesale value. Multiply the wholesale value by 2 to obtain a rough retail value.
Example - 3 similiar items sell for $90, $100, and $110. The average is $100. 0.8 times $100 is $80 (average wholesale value of the example). 2 times $80. is $160. (average retail value of the example). My opinion only. Others may have a differing opinion. This item is not rare, nor is it exceedingly desirable; just unusual. Since it has a limited universe of cylinder heads that it can be used with, the universe of buyers is also limited. My suggestion would be trade the manifold for something your prospective customer has that you want. The most interesting fact about this item, is that Pontiac tried tripower on the racing engines, and immediately dumped the tripower in favor of dual four-barrels and single four-barrels (lets not forget the three-barrel) for their racing engines. The tripower was relegated to street engines. Jon.

I think the 61 SD tripower to the "right"guy is worth $300.It can be used on any 55-60 head IF you put on a 61 type front cover OR block the water hole in the front of the intake for the rubber doughnut.FYI,Tom

Tom, Don't you mean that the bare tri-power intake is worth $300.00? If it had carbs, they would bring more than that.

Does the aluminum intake offer any performance advantage over the cast iron tri-power intake, aside from the lower weight? What about the old Offenhouser 3-2 intakes? I passed one up at a show recently.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
