Stromberg 48 was introduced in 1934
Do you think there is an dangerous level of stress on your engine when using the Stromberg 48 dual intake carb?

How far do we 'stretch' "Period Correct" nomenclature ?
- 1928-1931 ?
- 1925-1935 ?
- '25 to pre-war (1942) ?
- Other ?

A little tighter sense of what we are talking about may produce a response that is a little closer to what you are asking.

My '28 Phaeton's 'touring' engine with stock Zenith / distributor runs very strong and 'snappy'.

My '31 Dlx Coupe, with Ron Kelley 'Touring Engine', with it's F.S. electronic ignition and Stromberg 97 carb., cast iron exhaust headers - runs like a scalded dog after a bitch in heat ! Just hearing the engine builds my adrenaline and chops ten years off my age.

I can't wait till I have my rig back on the road. Exact same set-up as Doug has.

On one engine I was going to use 4 Harley Davidson carbs because the have butterflies instead of slides but could only find one at the time. Another reason was they are easily converted to alcohol for racing.
I used fuel injection instead.

Winfield BB on original Winfield BB intake. Nothing better for period correct.

I have a Stromberg-Bendix down draft intake with a single throat Ford truck carb on my B motor with an original CRAGAR head. This was available through Ford dealers in 1931. Perhaps the first Ford SVO program

I once "inherited" a box of OLD Jeep stuff, welded up a manifold & used TWO Jeep carbs. Used bicycle shift cables, to operate them.

Hi RS
Going weak to rich: TS, TD, SY, RW, RE.

Try SY, then go up or down. A Lambda sensor is a great help here, or good rolling road.
