Tips for HP gain?

I have to respectfully disagree with the double pumper. Gears aren't nearly steep enough coupled to a 727. The CFM is ok but I think a vacuum secondary would be much better.

That's cool, but when my 360 was stock with stock exhaust manifolds, stock converter, and 2.45 gears it ran the best 1/4 mile time and best 60 ft time with the 750 dp. Other carbs that had a chance were a 600 eddy and 770 vacuum secondary. Proper tuning is key.
