Thread: stromberg 97`s on a 460 ??

Tweet

Hi does anyone know if anybody produces a inlet manifold to fit either 6 of preferably 8 stromberg 97`s onto a 460, or is there any other wild carb setups available ??

Speedemon

No. The selection of intakes for a 460 are pretty much limited to one 4 barrel, two 4 barrels (Blue Thunder) and tunnel rams with either one or two 4 barrels.

Only thing I think you could do is buy a blower manifold, made for like a 671 blower, and fab up a flat aluminum plate to fit it, and punch the appropriate holes in it for whatever carb layout you wanted.

It wouldn't be super efficient, but I know what you are going for here. You want the old timey look of multi carbs, so efficiency is not the main goal, looks are.

One 4 or two 4's will perform better in case that was a consideration.

You might take a look at http://victorylibrary.com/mopar/log-c.htm.

Maybe it will give you some ideas. It deals with making a log intake for Chrysler engines but the principles should apply.

Another thought, Demon, if you choose to go with 6 or 8 Strombergs you might TRY (emphasis on "try") to find 81's instead of 97's (smaller venturi).

They might make it just a little more streetable if that's what you want.

Jim

thanks for the replies, yes it is more looks than performance, I think the biggest problem will be with linkage to get them working progresivly
Other big problem is that i will have to import them myself as no one in the UK stock them , so it will be a bit of trial and error
My idea was why have just six when you have eight cylinders lol
Any other idea`s keep them coming all info will help one way or another

Since flatheads are popular, Strombergs are going to be pretty pricey right now, especially buying 8 of them. And I've never seen one that didn't leak. You have to limit fuel pressure to 3 psi. Nah, not for me.

There is something I would pursue if I wanted to do what you're trying to do. I'd make my own manifold from mild steel. Start with 2 pieces to bolt to the heads, maybe 3/8" thick and machine the ports openings and bolt holes into them. Then I'd locate 8 motorcycle carbs from a motorcycle boneyard. I'd determine the angle they were mounted at on the mc and mount them on the 460 using straight tubing and bends fabbed together however you have to in order to make the angle correct, like a ram induction manifold on the Chrysler 413's from the 60's. I'd make a shallow fuel tank to mount on the cowl where the rear of the hood meets the firewall. I'd make it maybe 5-6" deep, 3-4" front to rear and the width of the engine bay. Motorcycles didn't use a fuel fump, so this cowl-mounted tank will fill the bowls by gravity. Mount a float in the tank to signal an electric fuel pump when the float drops to a certain level and shut off again when the float reaches the top of the cowl tank. That's how you would fill the cowl tank from the rear-mounted main tank.

Wadda ya think?

I think I need a drink... because I have a 460 and I want to play with it too!

I've also been picking up Rochester 2gc carbs on Ebay for $15 t0 $ 20 each to use on a couple of tripower manifolds I have. The early ones (late 50.s to late 1960's) used the small bolt pattern and are perfect for most of the 4 bolt manifolds you can find. These were used on many small chevrolet small block 283/ 307 etc engines, and are a pretty good clone of the tripower carbs used on GTO's etc. If you want to get fancy, speedway sells the kits to make the bases have no idle circuits, for the outside carbs. Rebuild kits are about $ 20.00 at NAPA, etc.

These are vastly improved over the old 97 fuel leakers, and other early ford carbs.

I like the motor cycle carb idea!!!

"I think I need a drink... "

why not fuel inject it.... they had fuel injected 460s in some later model trucks.... and it would be kinda neat, and very driveable

Yeh could do that ,but looking for the old style look , wont get that with injection ,
As for the motor bike carbs , not sure about that will look into it
rochester carbs , will be as rare as rocking horse sh!T i think in the Uk

Please keep the idea coming

Yeah, I know the current trend is the nostalgia/rat rod look with tons of carbs on the engine, but to be honest they weren't all that hot back "in the day." In the early years of hot rodding we were trying everything to get more power, and we had very few places to buy ready made items, like we do today. So some really strange things started appearing on cars. Homemade intake manifolds of every description began to show up, including the log manifolds mentioned above. Because modern 4 barrel carbs hadn't shown up yet, we resorted to what we had and usually these were the old strombergs.

However, the strombergs were known to leak fuel very often, and I understand recent developments by people who still build flathead parts have pretty much cured that ailment. Also, as mentioned, 97's are starting to get very very pricey. If you think the rochesters would be a problem, unless you have some UK source for strombergs that I don't know about, you are really going to lay out some shillings for the strombergs.

The motorcycle carbs are probably a good idea from the standpoint of worldwide availability. Maybe there are some English cars that use something similar to the way strombergs mount and will give you that look.

Good luck,


Don

maybe give it a cross ram look using some carbs off of a yamaha xs1100 special.... i have 3 of those bikes 4 cyl 4 carbs, you'd only need to find to bikes in the junkyard and you'd be set..... the yamaha carbs are very well built carbs and easy to synchronize... they also each have their own K&N filter on them so they'd look pretty nifty on a homemade manifold

A cross-ram log manifold with eight SU's would do it for me!
