Bought a tripower... Please help me figure out what I have here
 

I bought this tripower setup. (See pictures below) It's definitely a 1966 intake manifold. I'm not sure what the carbs are because the tags are all missing. Does anyone know if there is anything I can measure to determine what CFM the carbs are and if they are correct?

The center carb was opened up and I think some parts inside are missing. The needle and seat, float, accelerator pump plunger and such are there, but I think the accelerator pump discharge nozzles are gone. I ordered an inexpensive used Rochester barrel (that should be for a mid 60's Pontiac) to dissect and scavenge for parts. I know I'm missing the choke pull-off and some other external stuff too. Hopefully I'll be able to scavenge at least part of what is missing from that carburetor.

Also, does anybody know what this linkage is? (Again, see below...) From what I've seen the stock mechanical linkage lets the center carb open most of the way, and only opens the end carbs near WOT. This linkage looks like it opens all of them equally... I this some hillbilly stuff or an all-out race linkage?

I'm thinking for starters I'll need to order the carb rebuild kits, fuel lines, filters, brackets, and mechanical linkage kit. The water neck appears to be incorrect so I guess I'll need one of those too. What else am I missing?

The linkage is either EELCO or one of the other brands of after market linkage. Hard to tell what the carb is off of.

Try these guys for parts, info and tune suggestions. Very helpful. Also the water neck is wrong but I think available as a repro.

There are 3 different water necks available from Ames depending on what car you want to use the manifold on. They have left. right and straight discharge angles.

64 Waterneck pointed towards passenger side of vehicle.
65 Waterneck pointed straight up and was shorter in height.
66 Waterneck pointed towards driver's side of vehicle.

Your waterneck is none of those.

Your throttle linkage is missing the trunnion clamp that is used to adj. when the end carbs come in. Time to upgrade the linkage?
X2 on Pontiac Tripower, Mike and John are very helpful.
Also ck with Dick Boneske, member.

Not a tripower water neck at all.Tom

I think I have a reproduction 66 water neck purchased from Ames that I will gladly give you if you are interested (and I can find it)


I am attaching some pics of the linkage and other views I found for reference a few years ago when I first purchased my car (since decided to use "original AFB")

The end carbs are definitely real Pontiac Tri-Power units. The front one is a 1964-1966 carb. The rear one is a 1959-1963 carb. They are similar in appearance and identical in operation and performance.

The center carb is not a '66 Tri-Power carb, but perfectly usable for your Tri-Power.

I can supply the choke pulloff & brackets, fuel filter and bracket, fuel lines & fittings, factory mechanical linkage, waterneck, choke stove for manifold, and the kits to rebuild the carbs (all three kits are the same for your setup).

You can personal message me for details and more info.

I also do restorations of Tri-Powers, and can color your carbs by the zinc dichromate process (the same as the factory did), rebuild the throttle bases, plate all steel levers and rods, assemble the carbs using all now consumable parts (accelerator pumps, needle/seats, jets, gaskets, and calibration to your engine (cam, cubic inches, accessories, etc.)

My vote Sir, would be to send the intake and carbs to Dick B, above, as he does outstanding work with the correct carb dipping (coloring) vs a paint job rebuild.
