The TQ and AVS are good design, but they are hard to find parts for. Most auto parts stores worldwde have holley parts, easy to tune and understand too.
Point of view, easy to argue. Though you do have the edge until the word, "Understand" was used.
AVS can use AFB parts. AKA New Edelbrock parts. In most any HP store. Maybe not Autozones.
I'm with ya on the cam. Chuck it. Grab a new one.
