Tripower Aluminum Intake Advice
I am interested in purchasing a Tripower Aluminum Intake for my 68 FB. I see them available on the internet for around $400. Before I plop down 4 bills for one I'd like to know how they have held up over time. Any warp, leakage, cracking issues? Any success or failure stories or advice on where to go for more information would really be appreciated. This is a street/show car with a slightly worked 400 engine (375HP) that is driven on sunny days. Thanks

Not sure which manifold you're asking about. The only aluminum Tri-Power made by Pontiac was the over-the-parts-counter '61 SD. I've had mine since '61- no problems with it. Over the years, there have been some aftermarket 3-2 manifolds for Pontiac (Offenhauser, and ??), but they weren't really copies of Pontiac Tri-Power design- I believe the Offy was a single-plane design. In recent years, a new aftermarket manifold has been offered, I think by our forum host, Performance Years (?). If you search these archives, you'll find some discussion of the new manifold.

Jack, the manifold he is talking about is the 66 Tri-Power manifold REPOP made in aluminum. I have one from the first run and it is an outstanding reproduction. I received an e-mail from Steve yesterday and he expects he will have the latest run of the manifolds this week. I think they will be cheaper this time around, maybe around $350.00 each. Check with Chris at Performance Years, he can give you the new price.

I run one from the first batch, very pleased. Bit of trivia, they were all date coded MrP-Bodys birthday, send it to him for porting, he does great work -Jim

I am also getting one from this batch.
How much benefit can be had by porting these things? I was going to match them to a RA IV intake gasket to match my incoming KREs (I don't want to cut on my original one). Is there more meat in the runners that can be removed for better flow? Jim, IIRC, you had MrP do some work on your carbs too. Worth the effort? |

I made several changes along with the carb changes, so hard to say. Went from high 12's to low 12's and now 11's. But I will say this, the venturis are beautiful! Has to move more air. I think maybe some super secret circle track tricks were used, MrP would be better to ask. BTW, the month and day are the same as MrP's birthday, not the year. Another bit of trivia, the intakes are marked CM instead of GM. I need to post some pics, mine is painted and to the average eye it looks just like the cast iron 66. I plan to keep running the Tripower, mainly because many people say they will not perform. I am sure mid elevens are possible. We shall see. -Jim

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.
