I pur a Pro Systems carb on my Roush 427R. The double pumper I chose was a bit over 1000 cfm, not fuel efficient, but hammers all around.

I always prefer mechanical secondaries over vacuum.

I like my foot to control the secondaries, not a vacuum diaphram and a spring.

... and I'm just the opposite. A properly adjusted vacuum secondary carb, that is the proper size for the engine, is a joy to drive both on the street and the track. But this is kind of like the BB v. SB threads....

I agree. I find it funny when people with DP's say they like the blast of power when the secondaries open when in reality, with any properly set up carb., the transition from primary to secondary should be seamless and not noticable at all.
