Tri power carbs on 440 six barrel?

[6PKRTSE]

Trying to find Six Pack carbs these day are more difficult now that Holley discontinued them a few years back. Also, costly when you do find them.
I am one outboard carb short from completing my set up to make the swap to add it to my car. So, if anyone knows of one somewhere. I don't care about what years or numbers they are. I can make them work.

Will the Chevy tri power 2 barrel carbs fit on a 440 intake? Will the oval air cleaner work? I’m considering assembling a six barrel setup but the tri power is half the cost and I want the mechanical secondaries. Not a numbers matching car, it’s a rr clone, so originality isn’t important to me.

Never tried the GM carbs, but what I did one time was take a band saw and trim three Ford Autolite two-barrel carbs and they worked great. Mainly because all three had accelerator pumps, and power valves, very smooth no stumble at all. I did it on a 340 sixpack manifold. Used mechanical linkage ran off center carb until about 20% opening.

They are out there. You have to search but they will be expensive.

About five years too late for Sonny, but the corvette "tripower" carbs will work fine on a 440.
The problem is, the corvette carbs, at one time , were cheaper, and more available, than the mopars. Not anymore. Now ALL the 2300 2bbl holleys are nuts.
I have a manifold, and I'm tempted to get three 4412 Chinese carbs, and a bandsaw, and have at em..... but not tempted enough to do it.

Just back from the dyno. Happy with the results realising my 750cfm BG six shooter is holding things back a bit. Gotta swap my secondary squirter cams to something more aggressive to reduce the lean spot when they initially open up. Any suggestions appreciated

Assuming those demons use holley parts, there are buckets of tuning parts for accelerator pump tuning. Cams, shooters, 5 cc pumps, etc.
I am NO carb guru, AT ALL, but I'd determine what size shooters you have, and go a bit bigger. And most of the shooter cams have a couple of screw locations that alter the shot.
Time to play!

Sorry for my ignorance, but is that a chassis dyno or engine dyno?

Sorry for my delayed response. I like the carbs. Mechanical secondaries are cool. I use a reproduced 6 pack air cleaner. Looks the biz and goes well with my air grabber
