Yep, they were the hot rodders choice from the very beginning and some very fast dragsters and other drag cars of the day ran up to 8 of these, even on blowers. But as Dodge mentioned, they are getting more scarce and costly. I think they flow like between 150-175 cfms each, so three of them give you just about the right carburation on most flatheads or sbc engines.
A lot of these were even converted to run on alcohol and maybe even nitro.
Arguably carbs like the Rochester 2G are a better, more modern design, but the strombergs still have that certain romance about them.
