Which Carb Gives a Balance of Power & MPG?

I'm going to say this...

My Offenhauser is a killer intake. A buddy even ran an Offenhauser on his Olds 455 and that worked pretty damn good on that. My seat of the pants dyno says "IT FREAKIN WORKS!!"...

New technology or "smu technology"...Give me what works even if it is 40 years old.

BTW...Do not believe every dyno test swap thingie you see in magazines. Sometimes dyno's get happy and certain parts are played up in the name of capital gain=$$$$..
