I am also one of those that favors factory stock, although I do have to say that the Edelbrock Performer manifold and cam does add a nice crisp power boost. The Q-Jet is a great carb., very accurate and will bolt on directly to the Performer manifold. All of my GM trucks that I drove from '72 to 2000 had Q-jets, never had a complaint with them. My '78 Vette still sports the original Q-Jet and runs great, I use Sta-Bil in the tank cuz the car doesn't see many miles, last time I put a kit in the carb was 22 years ago, I can start and drive it any time.
