saw this on Instagram, not sure what to think..

Never even heard of it. Looks to me like a home-brewed affair.
|
Pretty useless if you want my 2 cents worth, not to mention dam heavy with 5 Carbs on it!
The tuned runner effect of having a Carb on basically at the end of each Intake runner in the head would make for a peak power tuned lenght of 8000 rpm or more! |
1950's tech thinking. Run on the center carb until WOT and open the outboard carbs up. Not ingenious but kind of clever in placing the carbs in such a manner like you would with direct port injection...from a 1950's tech thinking process. No different in operation than a Tri-Power.

It's cool to look at. That's about it
|
Never. Never even seen an ad,J.C. Whitney etc. Trying to look closely at picture. Plenum for extra carbs?
|
No one has ever seen one of those most likely because it's a one of one.
BTW, it looks as though from the poor picture that it's a 65 and up, 2 bbl manifold with the other 4 added to it. I don't have a picture of another home brewed manifold I saw at a Pontiac show in Columbus. They took a 66 tripower manifold and cobbled 3 AFBs to the top of it. The guy was pretty proud of it, it did run and drive. He told me he, and his son modified the intake. When the show was over he was leaving and got out on the main road in front of the dealership where the event was held, punched it and the engine backfired, stumbled, sounded like crap, and he let out of it and continued driving. It was less than impressive, car I think, was a 66 GTO. Not to be outdone, there is two videos on Youtube with an olds 442 with 4 Quadrajets on it, it also runs like crap. Links to quadrajet madness: https://www.youtube.com/watch?v=Hy8rufA6Pyw https://www.youtube.com/watch?v=Qa00UNBah18 At a minimum, 2600 CFM, could be as much as 3200 CFM, yep that ought to work really well. If bigger is better, than too much, should be perfect, but it wasn't........:thumbup: Notice the revision in the first video coming out of the carbs on the road test. |

Innovation. Back in the day.
|
There was a guy running two Q-jets on a Cadillac 500 at Sears Point years ago...I thought it was cool.
If you consider the most common engine at the time was the SBC, he was thinking outside the box. |
When 4 carburetors just won't do, try 5! Tri-power? Who needs a stinking Tri-power? My car has Cinco-Power! Fuzzy Dice, not included.
|
If you were around back in the early days you have seen 6 and 8 carb manifolds.

Wow .Incredible stuff right there
|
I have a 4 carb setup for a Pontiac that I bought from a PY member that mounts 4 Rochester 2GC Carbs and uses rubber tubing between the plenums.
For sure Old School Carb (cfm increase) type manifold. The Man-a-fre 4 carb intake was one of the best ones in the day. http://www.superchevy.com/features/1...-your-corvette I have seen several 6 carb intakes over the years. Tom V. |
If you are asking yourself why did they need so many carbs. Well it was different world back then.

Thanks PontiacJim1959 for the information. I will have to spend some time on Mac's website, a local guy in Michigan. Tom V. |

"...apparently built up from a production Pontiac V8 intake manifold..." I don't recall saying that I "know everything about the old stuff". |
Clearly a More the Better way of thinking.
Don't know if you don't try ;) https://live.staticflickr.com/65535/...9163ff9a_b.jpg |
The website shows a modified Pontiac Intake but a similar olds intake (picture #3) obviously is a cast up piece. All I see if that when he put the article together he could not find a photo of a 5-1 cast intake for the Pontiac at the time.
Seems we had a similar discussion about Mickey Thompsons "intake and exhaust ports on the same side" heads were some insisted the heads were modded production heads. Have a great day Jack. Tom V. |
