Hello Mopar fans,

Attached are pictures of the aftermarket carbs that were on the subject 55 chrysler motor, 331, as received. Can anyone identify the model?

Any tips to watch our for in the Stromberg arena, as I consider whether to use them or go the stock route. Never used them before, unfamiliar with their temperament.

Thank you,
Mike

Looks to be a Stromberg "97". These were popular on multi carb setups in the 1950' and early 1960's. They are also being reproduced Stromberg 97

Thanks.

Other than, 'the cool factor', is there any benefit to using them?




In the attached u-tube video, towards the end, (~5:15) they have a camera on the carbs showing what goes on (in the corners?) Seems to be much sloshing going on. Something you wouldn't pick on on a dyno in a lab. Curious if this can be mitigated by multiple primary 2 barrels....? Or fuel injection.
 
The main advantage was that they were highly reliable. That coupled with their small size, about 160cfm, meant that three of them could be mounted on a tri-power setup and still maintain good low end torque on an engine of about 325cid. They were good on the street setups that doubled as weekend drag cars. Not so good for circuit racing as the floats would stick either open or closed. A friend of mine had six of these mounted on a drag star twin log manifold on a 425cid nail-head Buick engine. It was in a model A Ford roadster. It was a kick in the butt to take that car to the drive in and goose the throttle, it would shoot a 3' flame out the carb throats from the end carbs until the RPMS came up. Scared the crap out of folks making out in various stages of disassembly.

Ha! you've painted a funny picture of the startling carbs.. So, I f I get this right, they were reliable as far as drag racing goes, but not so much on circuit racing?
