i just put new plugs and wires cap on and no the motor smokes and shakes alot more than it used towhen you even put a little gas in to it it feels like its gonna shake its self a part i need help bad the ruck is a beast but its never scared me before now i wont even drive it down the drive way beacuse its shakes volently at least to me it dose the motor is a 327 in a 66 k20 lwb fleet

You must have the wires crossed. Trace the fireing order. Did you gap the plugs before putting them in. Sometimes the gap gets mashed shut while in the box.

This sounds like classic "crossed wires"
Don't panic just trace down your wires. If you had a bad gap on a plug it would just be a miss and a 327 with a one cylinder miss won't noticeably shake much. But 2 on the other hand would start rockin the cab. . . So if your wires turn out to be in order you better start lookin at Dim Dere plugs.

well after it ideld for a bit it calmed down but i gaped them be for i put them in but i will check the wires and plugs it dont rock rhe cab but you can see the motor moving a lot mor at idel it only moved on acceleration thanks
