I have been running a dual quad setup (Eddy 600's) on my Charger for a long time with no real problems. It's a basically stockish 440; Stealth heads, .030 over, 282/292, .465/.488 cam, shorty headers, 4-speed. It's been very reliable and maintenance free.

I'm wondering what real improvement in performance I would get with a correctly set up single carb. I noticed on my buddy's '68 440 Charger with a single Holley, it really has great throttle response and power.

I really like the visual impact of the dual quad at shows and such, but am I leaving a lot of power on the table?

Opinions?
