Mechanical vs. electric fuel pump?

thanks for all the replies guys! fishy68 and 1wildandcrazyguy ill keep in mind what you both said...be prepared to see a vid posted up sometime this week of the pump strapped on and the scamp fired up with open headers!
Longgone, what kinda car/motor are you running just out of curiosity sake...is it the same carter strip pump that flows 120gph?
