Default Barry Grant tripower

Has anyone actually used one of these? Guy has a new one in box for sale, not sure how they work but they look very cool.

Was that the one that tested in a car mag several years back and had a bunch of metal shavings in it?

If you can get it for a good price just remember to clean it out.

If you're going from a Pontiac Tripower setup to Holley carbs, why not go right to fuel injection? Once you eliminate the sexy look of an original Tripower setup, you might as well go for injection.

There are Pontiacs running 10 second quarter miles with Rochester Carbs. The same engine may run a few tenths faster with three Holley carbs or a good injection setup, but that's all the improvement you'll see.

A story on the Barry Grant Tri-Power System. I think I am the only guy who ever ran the BG system on a Pontiac.

Quite a few years ago a PY member bought a New Barry Grant intake system for a Pontiac.
He posted up on the PY Board that he was having trouble getting some bolts to go into the mounting holes so that the intake could be used.

He posted up pics of the intake and a PY member "BGTECH" worked with him to get a different intake even after the member butchered up the 1st run intake from Barry Grant.

(It took three tries before they got one that I could use but BGTech did his job.)

All that being said, Robert Williams (RIP ROBERT) bought one of the intakes (no carbs) and I built him 3 carbs that flowed 1100 cfm vs the Barry Grant SB Chebby carbs that flowed 250 cfm each. I do not think that Robert ever actually ran his BG Intake on an engine.

If you do a search on BGTECH you can read all of the threads about the intake.

Default Barry Grant Six Shooter

Be cautious and do more research before you make this purchase. I bought three of these units for re-sale when they first came out. I sold all three, but all the customers had issues. Barry Grant was of no help back then.

Wait to get feedback from someone who actually ran on of these on a street driven car.

Agree on the above. Like I said, I know where two on the BG intakes are, you sold 3 more of the units, Mike.

The BG carbs (they used on the intakes) were not ideal by any means.
My intake had true Holley carbs on it and ran fine (after the Intake was ported by Dave Wilcox in Virginia).
I had over $500 tied up in the Porting job.

The first BG Intake I bought at the Norwalk swap meet. It was laying on the ground. (Wonder Why, LOL)
I paid $600 for the intake. As Mike W knows they were going for a lot more than that from BG.
BGTECH did a great job getting me a BG intake finally (3rd try) that could be ported by Dave Wilcox.
I personally would save a lot of money and use a 1966 stock cast iron intake or a PY aluminum Tri-Power intake (1st run)
with the DASHMAN Holley to Rochester adaptors if I did it again.

The biggest disappointment with these aftermarket Holley 3x2 intakes (including the defunct Barry Grant Pontiac) is the carb spacing will not allow the Corvette air cleaner to fit. Same with the small block Chevrolet 3x2. It would have gave the engine bay a whole new look!

Personally the O'Brian Truckers "Ribbed" Air Cleaners when used with Pontiac "Ribbed" Valve Covers looks a lot nicer vs the shiny chrome Chebby Part.

And the air cleaners fit just fine on the Barry Grant Intake.

Default BG Tripower on a 462 cid in my 66 GTO

I purchased a BG tripower setup for my 66 GTO a couple years ago and I love it. I had a 400 cid with the original tripower on it for years. But a few years ago I replaced the 400 with a built 462 and I wanted to keep a tripower setup on my car but I would of had to do some modifying of the original Rochester carbs to have it idle and run right. Instead I was lucky to find the BG triple D induction tripower setup which came with Demon 2 bbl carbs. They are originally 50 cfm bigger than the Rochester's, and they have a lot more adjust-ability than the Rochester's. I've used the BG tripower for 2 summers so far and the only problem I've had with them is 2 of the carbs had small leaks around the site glass. All I had to do was replace the o-ring behind the glass and I did that while they where still on the car. By the way I love the site glass in them, another benefit. I look forward to this summer when I'm going to replace the jets and squirters to see what I can get out of them. I will attach a few pics of the BG tripower after I rebuilt it. One pic shows it with the one piece oval air filter that came with it. I shined it up and used it for the first summer, but it just didn't look like a Pontiac tripower. So after searching for 3 separate air filters and finding nothing that fits the D shaped tops of the Demon carbs, I just machined my own base plates and used my old original filters. The final pic shows the tripower in my GTO with the separate filters.
