[Fot] SU vs Stromberg

[rodkent at cox.net]

This will be a fun one to watch, I personally like the TR-4 type strongbergs the best. That's what I used on my SCCA national 6 for years before the webers were legal, never missed a beat. I think they are both good, but the friends I had running SU's seem to have to fiddle more. I think it's just personal preference. Good luck........rod

On the 1.75" carbs, the strombergs have a shallower float bowl, and 
the floats aren't oriented optimally.  On the SU's, the float bowls 
are deeper and you can orient the float pivots toward the front and 
rear of the car.  The strombergs, when mounted on the right hand side 
of the engine will have issues in heavy cornering left hand turns - I 
think they went rich, but it's been a while.  Car would fall flat on 
its face for a second until the carbs recovered.  Very 
frustrating.  Based on that experience, I'd recommend the SU's.
