I was wrong. My Fenton is very different - see pics.


Anyone have experience with this one How do they work? Can you run progressive linkage because one carb is in the center of the engine?

That arrangement looks like it would have very poor distribution between cylinders.

Damn. Are they all like that if you want to retain the original generator mounting position? I believe the slingshot style works and might be better. Yes?

The carburetors are going to be the same size and require the same spacing on any of the manifolds. If you move the one carburetor back to clear the generator the second carb will have to be further back to get the spacing.

Fenton and Edmunds had a not so great spacing of their "regular" 2 carb intakes offenhauser still sells them that style...how bad is it in reality ??...i prefer them centered.

I run a Fenton on a 21 stud, pumps in heads engine....having pumps in the heads makes fitting an offset generator somewhat difficult. You need to get creative. However, Zigster, with his C69A engine, could simply offset the generator over either head [his choice]. I like the fenton; although the porting is somewhat restrictive, it positions both carbies directly over the runners, nice and close.

Yes, you can run those with a progressive linkage (the front carb is the primary), but as "JSeery" says, the fuel distribution is not the best. Those things are always a compromise. If you want to run a generator in the stock position, get a 4 BBL manifold, or use a Mercury bored out to take a Rochester 2G. On an early engine, you'll have to make some modifications, but it will be worth it. (Or run a small alternator, which looks kinda weird.)

Just what is "one of these"? It looks like a single plane manifold; how does it run? Not criticizing, just curious.

I dunno what it is; just a picture I downloaded some time back off of the 'net. Doubt if it's single plane; I actually thought it mimicked the 34-35 'camel back' dual plane manifold, but by putting the carbs up high on risers like that [tunnel ram?], it enables running stock generator position. I reckon it'd run pretty good.

Looks almost like a 32 intake that been adapted with some kind of aftermarket 2 carb setup mounted to it.
I really like the old speedparts made by people before you could buy them easily.

The mystery manifold above appears to have "Jack Henry" cast into it if that means anything.

I found this older article from Hod Rod on some "performance" intakes. It seems the Edelbrock slingshot performs very well.

https://www.hotrod.com/articles/hrdp...old-smackdown/

That pic of the one from Brian, I think I have seen before, or at least some similar. From Monteray Speed Shop. If I had money, I would get one of the two in the link below...

I 'googled' Jack Henry - very interesting, early flathead speed equipment pioneer. I'd guess that the manifold of his I attached earlier, was the inspiration for others, such as the Eddie Meyer above, also Edelbrock slingshot.
Anyway, all I was trying to do was give Ziggy another option for running stock generator location with twin carbs.

I have a slingshot on my 21. I drive with it pretty much daily. The only thing I'll say about those is they need heat. It takes way longer to heat up and run well over stock. You have to learn how to drive with a soft foot, come on too quick and its typical of lots of carb it will bog down. Im very surprised tho' I have 21hg in fact has been close to 22hg on a cold day with the setup.

Check out the SPEEDWAY 910-15985 2x2 intake......designated for 8BA but easily adapted to earlier flatheads.........this intake is a great copy of the Off'y 560-1075.
Carbs are a bit close but centered ,not set back,on the motor. An alternator drops
right in on '48 on back motors and a generator fits nicely on an 8BA. Brand new
$219. Worth a look.

Charlie makes a good point, if you can run later style pumps and pullieys, you gain a couple of inches of generator room.
