  • Welcome to Forever Pontiac

    We are a community of Pontiac enthusiasts. The purpose of our community is to keep alive the Pontiac spirit by sharing (or showing off) our cars, discussing Pontiac, helping each other work on our cars and find information, plus attend various meets/shows/etc... To aid discussion, sharing, event planning and selling of parts/cars/anything, we have various parts of the website to aid this from Forums to an online Garage to Classifieds to even a Document Download Repository. You can find links to these in our navigation above based on what each section helps with (discussion, local events, learning, etc...).

    We invite you to contribute, find help or just view some of our member's amazing cars! Don't forget, we also have great contests from time to time (like our Pontiac of the Month and yearly calendar contest) and our Pontiac This OR That, a fun game where you choose the best of two randomly selected Pontiacs from our online garage.

    We look forward to seeing you around!

BG Triple-D Induction (Tripower)

Recommended Posts

I was fortunate to get my hands on a Barry Grant Triple D Induction setup recently. I don't see very many around and they haven't been made in 10 years or more. I still have my original tripower setup but I would have to have a lot of work done to the Rochester carbs to handle the new 462 ci motor I put in my GTO a couple years ago.  With the BG setup using bigger Demon 2 bbl. carbs I will bypass a lot of the problems with the smaller Rochesters. At least that is the plan. I will be putting on this tripower within the next few weeks hopefully.  I have a question for ya all.  This tripower setup came with one big oval air cleaner assy.. Barry Grant also offered this setup with 3 separate round air cleaners mainly for us Pontiac guys because it looks much more like the original setup. I'm looking for the 3 separate cleaners but they have to fit a D shape carb top. The Demon carbs are like some Holley's  the have a D shape top and not round like the Rochesters tops are. I have filters that fit the round tops but I'm looking for ones that fit D shape. If anyone know somewhere that sell 6" round air filters that the base is D shape, please let me know. I checked everywhere I can think of. I might have to make them myself  but would rather not have to. Thanks Here a pic of the BG setup. I shined it up a bit.

Hi Dale. I've always admired the Triple-D Induction from Barry Grant. Which is why I was ticked when he walked away from his business in 2011 and let it go from Chapter 11 to Chapter 7 bankruptcy. it was like he had given up on his business and employees without really fighting for it (because he never filed a reorganization plan with the bankruptcy court). I also use to own a retro-style Barry Grant wood steering wheel for my Lemans.

That said, have you checked the Holley website? Holley purchased Demon carburetors from the Chapter 7 liquidation of Barry Grant. They offer the following kit, which might be what you are looking for.
