Guys, you ain't gonna get any heat from me. I appreciate any help you can offer. I'm trying to get myself back into the mood to tackle the task of rebuilding this Duster. I was expecting at least the factory performance from the engine, but was hoping for a bit more. It's got an Edelbrock Air Gap intake, and a Comp Cams HE268 cam. The block was decked, also. Running a Holley 670 Street Avenger carb.
