Long story short, my dad is downsizing and he gifted me his 31 Ford Roaster and a boat load of parts. Everything is identifiable except this this one piece. He has no it idea what it is how to utilize it. Here's what we do know: It's definitely a component of some kind of intake setup. He acquired it in a parts swap in the late 1950's. It's attached to two Carter YH side draft carburetors, most likely from a 53 or 54 corvette. It mates perfectly to a standard Stromberg intake manifold. If you attached it to a standard flathead manifold the carbs would be facing forwards. It came with a McCollum 39M supercharger, and it was supposed to belong to the supercharger setup, but that does not appear to be the case. On it's own it's too heavy to support it's own weight and would probably crack itself or the manifold (or the supercharger) on the first pot hole, indicating there there must be a missing bracket. There are no markings or numbers. It's made from cast aluminum. Any ideas on what it could be?
Paging @Hitchhiker Hey Matt, chime in and give us all the lowdown on what this is! @carbking may have some good input as well!
I would say it is an intake manifold. The three bolt mounting flange should bolt to a stock Ford flathead intake manifold, once the stock carb is removed.
and under the Carter carbs are adapters to the Stromberg 3 bolt pattern? and the are bolts for support brackets, as well. pretty wild setup...I can see why it sat in a box for 70 years.
The Caters bolt directly to the manifold. No adapters. The red piece is a throttle body. I believe that the bolts on the side a for a support bracket. They would almost have to be.
I agree with the blower intake synopsis and I couldn’t even come close as to who’s it is but it is neat as hell!
My guess is a flathead marine manifold. Low profile. They used side drafts on the Y block marine also.
Some of the early "dishpan" blowers had a mount for a single Stromberg 3 bolt pattern carb. Mounting twin carbs vertical would make it way too tall and side drafts were popular in the early 50's. So a pair of side drafts on a branch manifold. That manifold is cast aluminum, they made more than ONE ?
looks like the carbs would face rearward, not forward. has to be a bitch to get the back nut or bolt on. my guess is marine application also or next guess, possible a home made one off intake somebody made or had made
Too many pieces removed from the carbs to tell original application from the pictures; BUT the tags ARE present. The numbers on the tags will tell us the original carb application. Jon
You are correct. I just checked the car, and there is a plate between the carb and the supercharger that reverses the bolt pattern. I'll have to ask my dad why he did that. Anyway, mounting it facing the rear would allow a bracket to be attached to the primary intake, which makes more sense.
So, facing rearwards, attached to the McCulloch, it just barely clears the firewall, leaving little to no room for air cleaners. The marine application theory is looking more likely. However . . . if I could rotate it 90 degrees, I could mount it as a true (sort of) sidedraft intake. Anyone know of a flange that would allow me to rotate a two barrel carb, and by extension this weird-ass manifold, 90 degrees?
Those Carbs have slotted bolt holes, that oem on bottom side? Maybe done to slip in place because of clearance issue? Top side looks to be a bolt.
I guess custom built for supercharged FH powered early hydro where engine is mounted backwards, scared to read boost so vacuum gage or maybe for carb tuning under prop load. Maybe Holman/Moody. Neet piece, never seen one. I guess Dad likes you; Tell him I said Happy Fathers Day!
Simple.. You don't! With all the overhang weight I think a little gasket shellac and a little push down when tightening the support bolts will make the gasket seal. Or maybe take top half of super C off and bolt from inside.
I think that Summit vacuum gauge was added later, as Summit didn’t open till 1969. If you take that gauge out I think you could slip a nut through the hole for the flange. Just a thought…
My theory is that the guage on top is not supposed to be there. Those two holes line up perfectly It's possible that a longer bolt goes through that hole into the manifold. Or, you use a socket cap head bolt and tighten it with an allen wrench via the guage hole.
I can’t blow it up big enough to see for sure but the one on the last row second from the bottom might be the kritter.
