I know this is going to sound silly, but can someone please explain the difference between annular discharge and drop leg boosters in Holley carbs?  What are the benefits and draw backs to each, and which use (street/strip) does each one work better for?  I have asked just about every one I know this question and every answer seems to be different.

Incidently the vehicle in question is a '67 Chevelle with a 383 stroker. It sees both street and strip use, running in a local bracket class.  The engine has 11.5:1 true compression, 0.630 lift roller cam, and Proaction iron lightning cylinder heads.  Typically the car is driven just over an hour each way to the track instead of trailered. It runs consistent 11.60's n/a and has gone a best of 10.25 on a small shot of spray.

Any help you can provide is greatly appreciated.

larger booster=better atomizing, annular boosters help low end power but can so called "starve" or run the engine out of air at high RPM where a small down leg booster wouldnt. About track performance check out holley's website under their tech articles but i believe that a down leg booster is more for a manual tranny light car, narrown operating band and vice versa for the annular

Thanks for your help, we currently have an overly reworked 750 double pumper that is pretty much shot and are looking to replace it with something with more future potential.
