quote:vacume advance, as vacume is 18 to 20 inches in a stock cam, a street racer will only have 13 to 10, drag cars 4 to 6. a good carb for your application would be a 3310 vacume secondary carb, commonly called a 4410 ( double pumper) the 3310 does not share the secondary accelerator pump, but utilizes the venture vacume to open the secondary butterfly s, this carb is very trouble free and inexpensive ( you could buy 4 of these for the price of fuel injection)This is the carb that was on the SS 396 and other notable muscle cars of the 60's.
All things are relative:
you could buy 400 sets of points for the price of one fancy electronic distributor, points were used in every notable muscle car of the 1960's just like carburettors, mostly because that is all there was to use. But i wouldn't suggest it.
I played about, tuned, modified, tinkered with, rebuilt and even built from scratch carburettors for 30 years and i thought they were great, then electronics improved and became cheaper and EFI became widely available. Now i wouldn't give a tinker's cuss for a carb, just like i'd never have a set of points now. Some of them a darn expensive too. (you can't get 4 for the price of EFI)
I've converted a few 351's to EFI and there is NO comparison, even a cranky engine with a wild cam that will barely idle and a single plane manifold with huge ports will run as smooth as a sewing machine.
I was just suggesting an option that i believe is superior and would like to share with other enthusiasts, ultimately it's up to the owner to have what they are comfortable with.
