Sorry Gusto, I can't answer your question with 100% certainty, so I will just say "I don't know".
A few years ago I had an aftermarket SB Chevy tri-power Holley pattern intake with 3 Holley 2bbl carbs and I can say for certain the factory tri-power air cleaner DID NOT fit the carb spacing. The carbs were slightly closer together. I don't remember the name of it but it was something like FX3 or EX3 or ??????? I'll post some pics of it shortly.
Thanks,
Rex
Thanks Rex, just comparing the 2nd picture in post #11 with the picture below, they don't look quite the same.
My only point being, if he has a tri-power style air cleaner that fits, it could be worth nearly as much as the intake and carbs.
Except for the novelty of a 3x2 set up, it's kind of a waste. A 327 can't pull more than about 625 cfm, even at 7000 rpm.
CORRECT------------------ but a well built SB400+ with a roller cam sure can. And with patience, ingenuity and paying a lot of attention to detail, it can easily blow the doors off of many BBs.
Heck, the SB400 (built to immulate a 57 Fi 283) in my 56 starves for air above 5500 with the single air meter on my Bill Thomas modified FI unit, so I suspect it would do quite well with one of these tri-power setups (but I ain't swapping out my FI unit!).

I had the same 'running out of air' problem with the modified Rochester I put on my 383 Plymouth
Ask the owner if the car is 7/8 in size to a regular production car and whether it has three inch fuel lines to add 5 gallons of fuel to the system. If it has both of those features, it probably is a "Smokey" car.....

In Jonh Michelsen book Chevy performance vol. 1: the small block Chevrolet engine. There is picture of Smokey’s 3x2 intake. No number no nothing else info that it is very very rare.
My brother has an Offenhauser six pac SBC intake from the early 60's, employed as wall art. The spacing is for Rochester 2V carbs. They were common before the Holley 4V became the performance standard.
It would be easy to grind off the Offy script and falsely pass it off as something special.
Saw this post on another forum from a couple of years ago, looks like it was a stillborn Camaro option, L70, possibly with ties to Trans Am racing development. I don't think it has anything to do with Vetts, but you never know...

I could check, but from memory this intake was developed to feed the Hemi Small block heads! This intake due to restrictions did not feed the engine as well as a single carb or the dual ram (Smokey ram), that Edlebrock ultimate stole all credit for and robbed Yunick of their deal on royalties!
Just as on the big blocks, they found the single Holley on a high rise a better combination on cost and performance!

I will not attempt to debate that issue--------------------BUT DAMN, it sure looks impressive when you open the hood!!!! And if it had a Winters foundry logo on it, I'd sure find SOMETHING to put it on (as long as it didn't have an FI unit on it-------------FI trumps anything!).
