Default Unusual carburation on Flathead V8ís

Hey gang it might be fun to talk about and share pictures of unusual carburetor choices on Flathead Ford engines. Iím really talking about anything other than the normal 3 bolt 94 Holley/Fords and Stromberg 97ís.

Iíve looked on several occasions at some Italian ďVeeĒ engineís with their Weber and DelíOrto carbs and thought hmmmm???

Carbs like those ^^^ are often designed for 60 degree V6ís and V12ís which have narrow intake manifolding like our Fords.

So Iím curious if any of you have strayed from the beaten path. Iíll bet thereís a few that have used a Rochester 2GC, another good one.

What about Autolite 2100ís and 4100ís that came on small Ford V8ís in the 60ís.

Let it rip fellas if you have anything to say about this. Very interested to hear what youíve done or plan to do in the future.

Thanks!

I've seen one barrel Marvels with a Stromberg/Holley type base. Someone told me they were replacements. Same CFM, just one large single throat vs. two if I recall correctly.

I also think there were some 3 bolt Strombergs that had "L" backdraft horn that were used on Studebaker's of some sort. I could be wrong on this.

This is probably not what you wanted to see, but here are some pictures of my attempt to put a Quadrajet on a flathead. I figure if the would run on a 3.8 liter Buick, they could be made to work on a 3.9 liter flathead. I only had a couple of junk Quadrajets, and I couldn't get it to run worth a shit. I have a bunch of other stuff going on, so I abandoned the project.

I do plan to get back on it some day.

Probably should have used an adapter that had 4 holes in it, not the open one.

You're probably right. I had a bunch of parts laying around and I thought I'd try it. I had zero dollars in the attempt.

Mike Davidson from Austrialia use to offer a dual or single quad set up. The base used tops from Offy OHV V8 manifolds.

I saw this one at a car show a few years ago. Looks like a quadrajet on it. I never heard it run but pretty sure he drove it to the show.

I can't see it very clearly, but I think that's a 4G.

Au contraire Tubman that is a very interesting project. I hope you get a chance to try it again.

JMO but a quadrajet on a flathead is just plain wrong.

Can't be wrong if it runs right! A Q-jet from a 3.8 Buick etc. should be jetted right ,or at least close, and the small primary throttle bores are ideal. Those huge secondaries have an adjustable air valve above the throttle plates so no danger of over-carburetion. Just find or make a good flowing adapter and you're good to go with a little tuning (which you should do with any carb).

Not true, IMO.

Happy to be running a 4bbl. on my flathead, but even though it's a 4bbl. it is operated as 2bbl. carb. 99.9999% of the time, just as I suspect all the rest of the 4bbl. equipped flatheads are.

These are probably prohibitively expensive but dang they look like a perfect match to a Flathead Fordís narrow intake manifold.

I think Tony Baron made a Weber intake for flatheads at one time

My fantasies are more toward exotic, than performance. I've been thinking about running four updrafts.
