Thanks Denny you must be a night owl too...That made sense. So actually the reason my engine kept dying when I tried to adjust that is because it wasn't breathing correctly and in sync w/ all the other cylinders right? I mean I tried that before but the engine would keep dying when trying to get those last 1/2 turns in. Is this normal for the engine to want to die before you get every polylock/rocker adjusted correctly....Do you just have to deal with the engine wanting to die all the time until all the rockers are set correct. Does having a vac gauge hooked up at the same time have any merit? This is probably the last hurdle I need to get past besides putting in the 3.42's Thanks
