Edelbrock is a newby in the carb world?
As every brand has their info listed on their sites, and everyone of them thinks their stuff is best, I personally would be hesistant to be contacting the fabricators themselves as it sounds like you're fairly susceptible to 'advertising text' and info.
I would also look for people who are actually using the products, and then base my decision on that.
Actual users are the ones that will most likely give honest and real world information about the bad things some products might have. Online supportforums for both brands are also great source of info where you can easliy spot 'trends' of the more common issues people run into.
Brandnames and costs aside, my personal choice would always be port-injection over throttlebody injection.
