The factory auto Trips would have had a huge distillery of vacuum hoses, canisters & dashpots. I have yet to see one that is still on a car after 40 years.

My '66 GP has got a set-up with solid rods that snap together & are rigid. I believe it is a factory 4 speed linkage converted to use on an Automatic.

The Pics you have there look to me like that linkage would be subject to binding up. The angle of the linkage with respect to the plane of the outside of the 3 carbs is critical from my experience. The drooping on that rig is asking for trouble. I have to stomp the crap out of mine to engage it & that does not look like something I want to be stomping on.

...I don't know either, but have you tried a Google search?

when i get a chance ill snap a few shots of my end carbs. the stuff mentioned in google sounds more like a lube where what iam talking about is a silicone type stuff but made to hold upto gas. it just brushes on around the edge of the blades and where they meet the bore. there use to be a guy name....i think carbdr on ebay that use to sell small tubes of it for about 20 bucks, its real hard to find

Car looks much better with the parts car chrome on it, it's in pretty sorry shape but looks decent from 20 feet, can't afford to have it redone right now.
Got the manifold on the parts car, still need distributor, vacuum line parts, linkage parts and various brackets to hold it all before trying to start it, i'll keep updating as i go along. Thanks to all for the info. provided.

Car looks good enough for me. '65 Convt with GP trim & taillights.

From what people have been suggesting for its application, it looks like it's supposed to act as an extra insurance for a tight (vacuum-free) seal between the throttle blades and their bores.

When I was reading into the vacuum leak problems while rebuilding my tripower I heard of a different chemical product for that same purpose. The stuff I had heard about also had a thre-letter type name with some numbers attached. But the stuff I had heard about was supposed to be very hazardous and not recommended. I'd like to glance at the MSDS for the DAG stuff to see what sorts of things the manufacturer cautions against for it.

Has anyone here actually done their tripower and used DAG?

[mikediaz]

Ah, found the MSDS on it here:
http://www.laddresearch.com/wsmsds/DAG213.pdf

Seems to have typical (but still worrisome) health hazards -
irreversible damage to eyes possible if contact is made
several known carcinogens in it (and I'm not just talking about the ones beknownst only to the state of California!)
Kidney damage if you inhale enough of it, poor memory. Some of these may be common in many chemicals but if anyone does use it, please be cautious and wear adequate protection. Also, it mentions dangers of inhaling dust created by sanding/etc surfaces that have been treated with it. In case anyone does future tri power projects and lightly sands / emerys the bores - careful in case they have been treated with such stuff in the past.

Alright I think that's a solid enough warning for all.

Well not sure if i'll be using dag 213 but i did talk to dave at daves small body hei about a distributor, sounds like he'll be able to fix me up. Waiting on parts from Py and ames to get things rolling, still need a few pieces to finish the linkage.
Still looking for close up pics of an automatic big car tri power with direct linkage, anyone?? also need a source for the double belt pulley that mounts to the water pump. More updates and photos to come, thanks to everyone for the help thus far. Jim

seem to recall factory 65-66 factory service manual had details on tri-power and MPC had illustration and parts shown. Dougs carb book or others have info on 2gc carbs. you could contact the local GTO club in Houston. www.gulfcoastgtos.com Some of their people have tripower on both full size and GTOs.

Here's a picture of what at first glance appears to me to be original linkage. it was a quick google image search for 1966 pontiac tri power. It's not too up close but int he future when you see setups, at least you'll have a better idea of what original more or less looked like.

I know AMES and Performance Years sells repro linkages, ebay usually sold a good little kit for about $100 with most of the pieces. Just mentioning some options!

[Dick Boneske]

The linkage as pictured in the attached photo of a '66 Tripower I recently restored, consists of the slotted rod, center carb lever, rear carb throttle lever, and misc. studs & bolts, along with written instructions. I manufacture the linkage and sell it for $50. If you have any questions, PM me.

[65FATCAT]

Ok Mike and Dick both of your pics appear to use the throttle cable, which would indicate a gto, the big cars i've seen all have the solid rod coming from that hinge thing on the firewall, does this make sense? maybe just the auto tri powers for all size cars have the solid rod, i don't know, and allmost every tri power picture has a different bracket for the return spring. I think i'm starting to develop a idea of what it needs to look like, but if someone had a linkage photo of a bone stock auto big car tri power that was in the car, it would help. Still waiting on parts, i guess i could have sprung for air delivery but i'm too cheap.

If these help here are pics I found of a 63 and 64 gp autos (I know I know not 65) but it gives you a idea for full size cars, pics show the top rod has a plunger system? to give the play before the end carbs open up, bottom rod goes to kick down linkage (picture you show only has two rods but you said it was a auto car?) as for the linkage on the 66 2+2 thats all custom stuff I have the same junk/stuff on a 64 tri set I have.

Guys, I can vouch for the pieces he reproduces...they look great and work great.

[Dick Boneske]

65FATCAT,
The '66 big Pontiac linkage is identical to the GTO except for the stud that engages with the throttle rod from the firewall. The big car center lever has a ball stud that the throttle rod snaps into. The kit I described for the '66 big car Tripower has that ball stud instead of the straight one the GTO's use.
