Is anyone running a Winfield 5H sidedraft carb? I have one and wonder if it'd be too much for a slightly warmed up T motor?

No, it's a HORRIBLE carb, you'll hate it, just send it to me and i'll be glad to get rid of it for you!

I run one, they take a bit of finesse to get it dialed in (they can be a little "fussy"), and be careful as some parts are fragile as heck, but once you do you might just be impressed...

I wonder how "warm" your T is?

Well the current motor is "factory cast iron pistons" stock. But I could see myself doing the next one with aluminum pistons, a Waukesha head, SCAT crank, just enough porting to smooth the intake passages, and a slightly higher lift cam. I've got a mid-1920s Winfield pamphlet that listed the 4V for Ford and 5V for the overheads. I have the 5H (legacy from a friend) and I know of a 4H that I could dip into savings to get. I just wish I could travel back to 1926 and drive up to Glendale and ask Ed Winfield which he recommends.

Hey Chris. i couldnt see wasting a winfield on your current motor. A larger intake manifold & a good nh would improve it maybe.
Them iron pistons gotta go.
Aluminum pistons will enable more revs, but wont improve compression, unless you go to hi domes.
Ricardo head is not really a higher compression head. It does have a better combustion chamber that will run better. CC it.
The scat crank "T" adds reliability & smoothness, no more compression.
smoothing intake & polishing exhaust ports will help.
A new 290 Stipe cam will help a bunch. Get a GOOD cam, not a cheap cam.

Ideally you should get the compression up to around 6:1
She has to breath! A or B exhaust & intake manifold will make a big difference.
Just throwing on a different carbonator wont gain you much unless you are going for SEXY.

Performance is a package, not a simple piece meal task.
Call me & we can discuss it further.

Give me a shout out PM... I've been running Ed Winfield's carbs for 20+ years, and I love mine (which is why I said I'd take it off your hands!), I seriously believe if Winfield had made a deal with Ford to supply his carbs stock for their cars they'd still be around today (and that guy, Tillotson, would have been relegated to the bin of history!) , they are just that good a carb system... That "jet pipe" (when you get into yours you'll get what I'm saying) is part of both the magic and the PITA of them, but Ed Winfield had such a great idea, had he not been bowed under by his competitors his work would be legend even today... combined with his WOT barrell throttle (which for some reason people just don't get) it almost is the equivalent of throttle body fuel injection...

Put modern pistons, valves, and flow your head and intake, and you will have a 50+ MPH car (and make sure your brakes are up to it)... But I wasn't kidding about dialing that carb in, as they are a picky, touchy bastage, but once it's dialed you will NEVER go back,

A friend of mine is running a 5H on a basically stock motor with a T Fronty head. It’s a sweet running combination. It wouldn’t take much to get a flat head to run with similar results. A little compression... a bit of cam... and a much larger intake manifold will liven up an otherwise stock motor considerably.

The barrel valve carbs are known to distort and wear around the barrel causing vacuum leaks as causing idle issues. The pot metal model M’s are far worse than the aluminum V and H models. I built an oversized barrel and bored the housing to match for the 4V on my ol 27 roadster years ago. This greatly improved the idle and overall performance of the carb
