You do realize that the Edelbrock carb is just a Carter AFB that was used by Mopar for years? Thermoquads have always had the reputation for being hard to tune.
On the last Garage Squad with the 68 Chevelle the first thing they did was tear off the Edelbrock carb (which looked fine) and threw it in the junk pile. Later when they were doing the start up, behold the Holley replacement. So I guess they really don't know what they're doing?!?!
