Asking for what is the best will always get you a ton of opinions...

I have a 57 3100 with the 235 in it and I have the fenton dual exhauxt and the factory intake with a single rochester on it.

She starts like a dream, runs great, gets decent mpg and has never left me sitting on the roadside. Don't knwo if that qualifies for "BEST", but tha tis my experience. It is in my plans to upgrade to the dual carbs in the upcoming months, so I will get to see how hard it will be to keep the two rochs in sync.
