Remember the BG 66 Style Tri-Power Intake?
Here are some pics of one i put together some years ago:
A) It took me 3 tries to get a good Pontiac 6-Shooter out of the BG people but BG-TECH who used to post on the PY Board occasionally, really helped me out with eventually getting a good one. This one has been Ported by Dave Wilcox. B) The Carbs are not the Barry Grant stuff. They are Competition Series Edelbrock/Holley Mechanical Secondary race carbs, similar to the Race carbs that were supposed to be installed on the Ford 366 NASCAR engines. The carbs were disallowed therefore Edelbrock bought the rights from Holley to sell the carbs to the MOPAR & CHEBBY racers. 3) The Air Cleaner is a Ford 406 Tri-Power type unit (uses Ford Oval Air Cleaner) BUT the Base is machined for a Pontiac Carb spacing. 4) The Linkage I made from Pontiac Pieces for the Normal 65-66 Mechanical Linkage Tri-Powers. Tom V. So what "toys" have you come up with? I know Dick B has done the 64 Linkage.

Is that manifold stock height? It appears a little higher than stock.
I believe it was Dave Wilcox that has talked about producing a '66 aluminum manifold, but higher than stock. Do you know anything about that?

Most of it is an optical illusion.
I have one of the first run PY Aluminum Tri-Power intakes and when I compared the two intakes they are very close on the actual Air Horn heights. Tom V.

Tom,
If one wanted to retrofit 3 Holley's to a 65 Tripower, where could they be purchased?? What CFM's? I know it would take lots of fabrication, just what would function properly on a warmed over 421? Thanks

Yeah...same fellows that sent all my posts to Jeg's when I hammered them on their continued production of carbs with aluminum shavings in the bowls a full year after I called them to address the issue. Tried to get me fired but only got three days off since I wasn't lying about anything. Real sweethearts...those guys!

All of the OFFY Tri-Power Intakes function like a single plane, Jack, because of the large windows cast into the "divider walls" of the intake. They are like the 'U-fab log manifolds" with the hose connections as far as function but balance better as there is not hose wall friction to delay the cross-flow of the mixture.
Dave's intake would elininate the center divider/windows too. More like a mini plenum under all of the carbs. Tom V.

Any real-world info on the performance of a Pontiac with single-plane Tri-Power?

Tom, I have been trying to find a BG six shooter for years now. Do you know anyone that has one they are wanting to sell?
Mike

Mike, I know a very few were sold to Pontiac Guys.
I bought a first run 6 shooter at Norwalk (laying on the ground) for about 1/4th of the price BG wanted and got screwed on that deal. Basically 1st run and 2nd run stuff had mistakes where you could not bolt the thing up without a lot of rework. I worked with a PY Member "BG" who worked in BG sales and eventually got a proper intake out of him. Wilcox ported it for me. So there ARE Pontiac 6 shooter intakes out there BUT assume that you will need a lot of welding on the thing if you buy one, Mike. I have no sources/contacts for the manifold after BG was bought by Holley. Should have bought a bunch of BG stuff I did not buy. If I come across a person selling one I will give you a shout, Mike.

Thanks, Hope Mike can find the seller and discuss purchase/inspection with him.
Main issue on most of the set-ups was the 275 cfm (SB-CHEBBY) carbs they installed on the intake. 500 cfm 4412 carbs (350 cfm 4 bbl rating) work really well. Tom V.
