Can you go into the details for us?

Also can someone go into the details of swapping the vacuum set-up to a manual linkage?


I also found this post on the Corvette Forum about Tri-power performance compared to a modern single 4 bbl set up.

Corvette Enthusiast did an 11.5:1 489 buildup using AFR 315 CNC heads. (May 2006) They tested 3 induction systems: Holley Strip Dominator 4150; Edelbrock RPM Air Gap and a modified 67 Tripower. The 4-bbl intakes were tested with a Holley 950 HP carburetor. The results were impressive:

RPM Air Gap w/Holley HP 950: 643 HP @ 6400; 594 lb-ft @ 5100
Vic Jr. w/ Holley HP 950: 641 HP @ 6400; 603 lb-ft @ 5100
Tripower: 655 HP @ 6200; 591 lb-ft @ 5100

I also emailed Corvette Enthusiast to see if I can get a copy of the article.

Re: tri power for a bbc?

I recall typing up a detailed blueprint and posting it here soemwhere, but it was probably deemed "Chevelle irrelevant" and not archived. I'll try some searches. Apologize, but I simply dont have the spare time to write it up again right now.

Post a WTB ad with a willing to pay price.

I'd also post one on the corvette forum, the HAMB, and any other free to join on line car website.

Ya just never know.

There were almost 4,000 67 tri-power vettes produced. I can't believe the remaining manifolds are all still in use.

Personally, I'm gonna keep trying.

Any idea what you may have called it? I will ask Al to help us find it.

I think I used " blueprint" in the title, and my user name was "Gene Chas".

Re: tri power for a bbc?

Yeah, that old winters intake wont stay that clean if you run the car any! I use a small base. I dont prefer the hulk look of HEI's but.. no big shakes.

Re: tri power for a bbc?

For what it is worth, I just missed out on a 69 3 x 2 manifold last weekend by 5 minutes. The seller sold it for $750.00. Also included a original appearing air cleaner lid and base. I posted it in whats it worth.

Re: tri power for a bbc?

Looks like the carbs are too close together to use a metering block on the rear carb, is this correct? Or can you squeeze it in there?

Re: tri power for a bbc?

I didnt read through this whole thread yet, but saw where someone had mentioned the Barry Grant Six Shooter system...STAY AWAY FROM THAT PIECE OF JUNK!!!!! It is the wost quality I have seen....bad finish, horrible fitment...We sent ours back and checked with Jegs to pull a few from there shelf to see if it was the same, sure enough...P O S !!! They sent back there whole stock on them as well. I have some pictures I will post up later....stay away!!!! Barrys quality went to ****.

I don't believe it will fit, the carbs are real close together.
On a side note, the Mopar six-pack air cleaner will fit the Chevy setup (& vice versa). Maybe ole Mopar did a little copying back then? The only other difference is the fuel lines are on the passengers side. Otherwise the Mopar carbs will work.
