Default tri power intake

with the 427 tri power setup, did it come from the factory with only the GM intake?

the intake is a Winters Foundry "snowflake" intake, if that's what you mean?

I had been wantiing a tri power, i know a single carb is better but a tri power is so old school cool, they are expensive, over my pay rate because for what ever weird reason there isnt that i know of any aftermarket bb tri powers, but elusive like bigfoot and ufos i thought i too recalled someone like weiand making them for a spell,

I would be interested in seeing pics of that intake as well. My car is an original 427/400hp but the tri power is long gone and its not likely I`ll be able to afford an original manifold for it. Maybe one day....

Every time i start thinking wtf ill buy a tri power ready to go,
I look at the price and think that i could build a fairly nice engine for that, and i back off, im far from a purist, i dig mods but yeah, if i had a tri power car missing it i would have to find one....factory correct even

I'm putting together a 427/435 tri power setup that I'm putting on a 496 in my C10.


yeah, they are stupid expensive. But it isn't even the actual carb and intake that's expensive, if oyu get one missing parts, getting everything else- choke, air cleaner, fuel line- starts to add up.


Though when I was researching tri powers, most of the info I found online said the 427 setup was the best flowing tri power you could get for a big block chevy.

Like Bats said a Tri-Power setup is old school cool. I put on together in 2005 for my 69 and spent $3500 on parts.

I just purchased and put the tri-power back on my 435 and it was expensive.After you buy a used unit(about $3000) you have to get the carbs rebuilt,which cost me $1000,then I had to spend another $600 to straighten out the f%@ked up job the rebuilder did,then I had to buy the linkage,lines,air cleaner and misc stuff.I redid the heads while I was at it,I think that was around $600,was it worth it? Simply put,yes,but then I've always loved multiple carbs.By the way I've read that Zora liked them because the runners delivered the gas from an equal distance to thecylinders

So the 64 dollar question lots of tests have shown one 4 barrel will out do the tri power, but why?

I dig multi carbs too, my veedub stuff and my 66 corvette 327 ran dual side draft webers...coolness

That is a 68-69 427/435 intake and carbs. The "797" intake was used in 68-69 on 435 hp engines. The carbs are correct for a 68-69 435 also, but I'm not sure they are all the original carbs, for that intake. If I'm reading the dates correctly, it appears you have one dated June 67 (763), one July 68 (873), and one July 69 (974). The dates would normally be much closer together.

The intake has a date code on the bottom of it, but I can't make it out in your pictures.

The repair hurts the value of the set up, as does the mismatched carb dates, but I'd still put the value at around $3000. There are people who can clean up and restore the repair.

If the air cleaner bolts in the two end carbs, have an "M" in the center of them, you might want to remove them to sell separately. People will pay ridiculous money for just those two bolts.

it almost looks like the date casting is missing on the manifold??


I'm not home to double check my manifold, but i thought it was directly next to the other number (pic 4) that says what looks like "4259"


also I agree I'm seeing the same thing for the carbs dates and those numbers mean its not a matched set.


I don't think that setup will bring close to $3k.

Carbs have been bastardized by removal of the vacuum diaphragms from the end carbs. These were integral to a good driving system. The throttle linkage has been modified to a mechanical secondary linkage bu the end carbs do not have accelerator pumps.

I ran the stock Tripower setup for while on my 496 BBC then I swapped the carbs for a set of Mopar SixPack 4782/4783 carbs that are designed as a mechanical secondary setup. Accelerator pumps and jets (no plates) on all three carbs. Car ran like a monster but I was tired of the smell at idle and the fact that it would want to die on hard braking due to fuel slosh.

So, my ultimate solution is a custom port injected EFI Tripower. Manifold is an Edelbrock dual quad welded and machined for 3 two barrel throttle bodies. FAST XFI 2.0. All work was done by Bruce at F&B Throttle Bodies. This is all under a stock '75 hood with ~1/2" of clearance and filter that is 3/4" taller than stock. If I was using an L-88 hood, we could have used the Dual Quad Air Gap manifold as a basis.
