I just get all wet and steamy over multi-carb setups. I've always walked away from Weber conversions because I've always understood them to be finnicky as hell when it comes to balancing and tuning. Not that S.U.'s are much better, they're just the devil I know.

The biggest thing IMO with Weber DCOE's if that there are SOO many parts you can change....it can bet really confusing. Especially the emulsion tubes which really can change the transition into mid range RPM's. About 2 to 3 times the parts to change as in a Holley.
