It’s almost $600 with shipping and I have other things to do, dual carbs is not the priority right now, so shiny..... want to touch the precious..... so vintage... in perfect condition....rare.... I hate it when they say rare!!

This is the wrong place to ask for restraint from buying car parts.

The only thing that is going to stop you is if you post a link so someone else can buy it first.

Resistance is futile.

Do it

well, on the bright side you are no longer thinking about car parts.

Don’t do it. You can create a custom triple carb intake later.

Still better than Huge Jackman as hook.

Well there is a guy, Edgy that still makes this kind of thing, so does Stovebolt and Offenhauser I think. I might go for the Stovebolt single larger Weber set up at some point, people say it works the best. The flatheads can only be tuned so far, they hit an RPM wall and nothing else will matter so a bit of head work, a bigger carb and a dual exhaust kind of top it out, you can get maybe 30 more HP and better MPGs from a 230. This thing is pretty though, and actually old so I like that...

Actually a custom triple is on Ebay right now! But the 230 engines can only go so far, a good larger Weber set up from Stovebolt is best from what I have been reading, more research is required.

After reading that ad I’m ready to buy it and I don’t have a flathead Dodge. When I was young we briefly had an old Dodge truck that had one but that was a LONG time ago.

I have a friend in his early 70s who has been fooling with stovebolt engines for over 50 years. He’s built NASCAR engines and a bunch of other stuff over the years. I have a 250 and you can do some relatively basic arithmetic and compute the air consumption of your displacement at a given RPM, say, 5000 RPM, and it’ll turn out that the theoretical max CFM the engine can possibly use is somewhat less than 300 CFM. Those multi-carb setups are massively overcarbureted. And you lose the heat from the exhaust manifold in most cases...

He prescribes a Holley 7448 two-barrel for my 250, rated at 350 CFM, and an Offenhauser intake manifold that mates with the stock exhaust.

This looks way better than stock, and the connection to the head doesn’t invite some of the same runner length irritations and difficulties as some double setups I’ve seen for an OHV stovebolt. Still awkward and different virtual runner lengths w.r.t. the overall flow velocities in the plenum*, but as long as you make sure to use carbs with tiny enough bores that you’re not overcarbed, flow into the plenum should be pretty even.

*The center double inlet is the same distance from the carbs as the ones to either side, but because it can draw from both sides, its gas velocity is *half* that of the 1,2, 5, and 6 cylinders:

Which means that in an OHV, all the way to the limit you’d see the end cylinders choke out first, and that with any of them you’d get possibly less good mixing in the cold to cylinders 3 and 4, because the fast- moving air over the gas “dribble” under choke would evaporate differently. It’s like having a longer runner to the end cylinders in some ways, and shorter in others.

Shouldn’t be an issue here, not only because flathead, but because the carb bores are small relative to the inlets. Even though the inlets are sucking intermittently, the internal manifold volume is big enough that in most cases it’ll be swirling around some before entering any of them, at fairly even (low) pressure.

Performance increase, probably not much, but better running when cold and at medium throttle, I’d wager - and tunable for better economy with a small enough pair of carbs.

Yeah, I’m told a slightly better weber two barrel carb with the stovebolt kit is best. Once I finish everything else I will probably do that and a couple this I’ve been told really help.

The main fuel economy will come from the gears I’m swapping into the axles! But one of the board members of the military vehicle preservation association has been trying a few things, I think some people get a head from a 50's Chrysler car, head tuning and I think he said he back cut the valves. But so far I hear this kit from stovebolt is the best carb for a huge military truck with a 230. He also has a dual exhaust, I may do it someday when I run out of things to do. I still want to put an LSD in the Z, pretty much the only thing left to do for that car.
