Ok so ive got a Datsun 280z with a blown 350 sbc and th 350 in it . When i really give it the gas the car feels like it wobbling or shaking . I have solid mounts everyplace and the car is in great shape but ive never dealt with 400 horses in a 2,600 pound car .

Is it just the force of the torque making it wobble or vibrate maybe cause the car is so light ? everything is balanced except the front tires havent done that yet lost the lug key
