Hey guys, I found an ad on craigslist, the guy says the same thing I have said here. He just wants to know what it fits. But at first site I was thinking it was a 6 pack for a 440. But after a couple of minutes of looking at it I dont think it is. Maybe you guys can tell me?

It is an offinhouser intake. And their are no Casting humbers on it anywhere.

 

Could that be a tri-power setup for a GTO? I have seen that some where before or atleast the carbs look like something I have seen.

Did he have it on a Mopar or buy it from a Mopar guy?

 

i think its an offy "portosonic" probably for an oldsmobile or pontiac. I've never seen one with the tri power. Just a guess.

after googling it I believe you are right. Thanks for the help in figuring this one out guys. I honestly did not know they had put a 6 pack on anything other than mopars. But that proves how much I know. Thats why i thought maybe it was just a funky looking 6 pack for a 440 or 340 lol. But after seeing the intake ports on the bottom of it, I figured I was way off lol.

 

yeah your'e right. those old fords did have that funky port design with the over and under openings.

 

One of Fords "better ideas"

 

If that isn't an oxymoron, I don't know what is.

 

I forgot the T'birds used these and that might be a rare item that could sell to a collector for good chunk of changes.

I cant remember what Ford called the T' Birds with those on it and what motor they used. My dad is a big 55-57 T' Bird fan.

 

Yeah it would probably sell for quite a bit. It's not mine though I was thinking about buying it from the guy that had it for $200.00. But decided against it I wouldnt have any use for it. So I told the guy he should put it on ebay and see what it goes for, cause I'd bet its a really hard part to come across, especially being original not a reproduction.

 

All of the Big 3 had a 6 pac or Tri Power carb set up at one time. 2 of the more famous are the Pontiac Tri Power and the Mopar Six Pac. I dont think Chebie ever had a factory 3-2 carb arrangment.

 

Sure they did!!! 348!!! Never offered on small blocks, but of course the 'Vette setup had 2 x 4's on the 283

I can remember one in a station wagon, of all things!!!


You guys are right, tho. Just about everybody had a factory triple setup at one time or another. Olds, Poncho, not sure about Stude

 

man this is old. lol. I feel stupid after reading what I said on this now. It's def way too small to be a 440 intake lol.

 

Dont forget the 409. there was even a song ( 4speed dual quad positraction 409)

 

'09s never came with tripower, only the 348.
