I rebuilt 14 Q-jets in 2010 alone.
If your a first timer, it can be intimidating to attempt one, especially if its your own car, with no back up carb. Books are great, to an extent. But, there is NOTHING like seeing and hands on the actual parts, seeing how they all fit together. The books sometimes miss the
little tricks or nuiances on how a piece goes on or comes off in a series of steps. That can only be done by trial and error found by taking one apart and re assembeling one. Over the past 25 years, I've probably rebuilt 40 or so Q-jets, from the basic ones to the computer controlled ones. The best one was a tear down and rebuild of a members carb here on the parking lot at the NATS, 2 years ago.
Don't go with a Holly, they have thier place, but, not without thier own issues on our cars.
The 3711 Edelbrock Performer intake is a direct replacement for the cast iron stock one, just way lighter. The height will be exact. The Performer RPM intake 7111 is higher and will have shaker clearence issues.
