I have a 3310-1 780 carb that David Cook did. It is the Vac carb that is legal as a 750 in some comp & SS classes. I have done some testing with it in my SS/DS car. Before I paid David & started testing I had Wesley check out the carb. He made no mention of the carb having 4 corner idle.
I really don't see that it is a big thing because I have cleaned up the idle circuits on non 4 corner carbs when I do dyno testing of the engine. It is no big deal to change air bleeds & fuel bleeds. It just isn't as adjustable as with a screwdriver. I agree the screws & outside of the metering block don't look stock. (like the original carb) I would like to know the out come because I was about to let Kevin Helms try this carb on his 396 combo. I would like to give David a pat on the back. This carb had a very nice fuel curve, right out of the box...
