1957 283/270hp dual quads drag testing on a 350

Allan,
There are no angle plates.

I suppose I could cut some wedges out of Oak wood for a test. But then I'd have to think about the angle so as not cause the floats to introduce a different problem.

But first I like to rejet the secondaries. Thanks for the numbers on the needles and jets.

With all the different things done in testing so far and the same-old dull hesitation regardless, I'm thinking about pulling both carbs down on the bench and blowing the passages with compressed air again. I'll try to get some oversized secondary jets.

Unfortunately for the next 2 weekends we are having the Texas Muscle Car Club Challenge series races here so I'll just have to see if I can just get it consistant until getting back to the serious testing.

Thanks to all,
