i'm running stock suspension, adjustable upper and lower control arms, custom cut drive shaft. i'm now thinking i might have a balance issue with the crankshaft. the engine vibrates the car pretty good. the cam in the motor has around .680 lift, so i was thinking the shaking was from this. i was told this could be a problem. so now its on with more cage and send the rotating assembly to the machine shop. i'm going to eliminate these two problems anyway. thanks for the info. i was hoping somebody had these types of problems to steer me right. i will post what i find.
