just put a new motor in the camaro,it has a crane 292 cam 230 duration 465 lift single pattern , running a 3000 stall converter if i idle the car in gear under a 1000 it shakes and vibrates pretty bad, is this because of the 106 lobe sepperation, or should i look for something else,the timings set at 16btdc and 32 total at 250i can idle the car at 1200 in gear but i have 1500 in nutural
