Putting together a 2x1 set up on my 51 Dodge Coronet. I’m keeping the gyromatic M6 transmission so the Stromberg BXVES-3 carb (w/ electricals for M6 operations) will stay. I need another stromberg to pair with it, but unsure which model to seek out. I only need the one BXVES-3... so is there a specific model (w/o electricals) of which I need to pair it? I would assume another BX series model... but which one?? Thank you and I hope everyone is staying safe & healthy! V/R, Mark Sent from my iPhone using H.A.M.B.
By far the easiest, and probably the least expensive choice is another BXVES-3 with the same code number as the one you have, and disable the extra circuits for control of the M-6. Second choice (assuming you have a LOOOOOOOOOOOOT of time) would be to acquire the BIIIIIIIIIG Stromberg book, and research. Third choice would be to find someone with the book AND the time, and pay them to do the research. This is not an offer. I have the book, but not the time required. You will want to match: throttle bore, internal main venturi, idle air bleed, idle restrictor, idle bypass, and main air bleed. Main jets, power jets, and idle jets are available; so less critical, as they are easily replaced (although the power jets and idle jets are not inexpensive). The model for which you will be searching is a Stromberg BXV-3 with ALL of the above matches (if one exists). I have data on 71 different versions. If you cannot find one of these, then it might be possible to modify a BXVD-3 (I have data on 48 different of theses). A matching code numbered BXVES-3 is my suggestion. Jon.
Assuming your engine, other than the dual carbs, is basically stock. If so, suggestion: Once you have found your matching carbs, BUILD BOTH CARBS COMPLETELY STOCK! You now have a repeatable baseline. GUESSING that you will find the two carbs to be slightly lean (reduced air velocity in the venturi, and the idle circuit) and recalibration will be in order. Both the idle tubes and main metering jets may be enlarged IF NECESSARY. If the engine runs lean, and you have good compression, and ignition, TEST a new calibration by raising the fuel level in the bowl. Raising the fuel level by 1/16th inch approximates increasing the jets by one calibration size (0.001 idle jet, 0.002 main metering jet) WITHOUT drilling. Testing can save you money! Guessing you will need maybe two sizes richer on the idle, and one size richer on the main. Remember that if you drill either idle jets or main metering jets TOO large, they will have to be replaced. The "old wives tale" (actually an "old husbands tale" as old wives are smarter than this ) of soldering the orifice closed and redrilling doesn't work; plus it has the downside of maybe getting solder in an undesirable spot in the engine. Fuel flowing through the jets will erode the solder just like the Missouri River erodes levees. Also test when the power valves (a.k.a. economizer valves) are activated. To really get the best fuel economy, it may be necessary to replace the power valve actuation valve springs with those that are slightly weaker. Jon
You think this a good one to start with or is it a POS? Also... if you run a carb-reman business... I’d be willing to give you my business to reman both since you pointed me in right direction. Just gimme an honest price and I won’t look elsewhere. Just lemme know!

No longer rebuilding, too busy with the manufacturer of kits. The Stromberg "B" series carburetors are excellent, much better than the "E" series revered by many on this forum. On a basically stock engine, I think they will be lean, but the condition should be correctable. One other thing to consider (I don't know the port arrangement on the Dodge cylinder head, so I don't know), but sometimes 3 smaller carbs will run MUCH better than 2 (again, depending on the port arrangement). Jon.
Totally understandable... do you think the one in the link I sent you can re-man’d??? Thanks!!!! Sent from my iPhone using H.A.M.B.
