DP carbs with automatics

I was thinking that a mech. sec. carb would be simple to set up. Never had one, just thought since I would be doing a lot of quarter mile action with this motor it would work better. Haven't bought a carb yet.....

The best advice I could give you is get a 950 hp holley out of the box. Put 2.5 power valves in it. And play with the jetting to get it to the right richness or leanness. My 340 went 3 tenths faster with one of these over the Carb Shop Specialities prepared 750 I took off. These carbs love to be raced!
This is how mine leaves with the 950 and a automatic.
