ok this may sound odd but theres nothing i love more than when i rev my bad *** 3.4 up (lol) i get a little shake in the whole car now ik i wont get the same effect as a v8 but can i run some sort of support from the motor to the body and get a little more shake out of it or will this be a bad idea

 

poly trans mount will give u more vibrations.

 

Uplug a plug wire and take the balancing weights off the tires. That should give you plenty of shake to keep you satisfied. lol

 

lol thats not what i ment

 

Polyurethane mounts would be the best idea, but I don't think you have any real vibrations there V-6, V-8 or not, these cars run pretty smoothly until you mod them pretty hard. My LS1 runs really smooth as well. Good luck on that, but I wouldn't add anything to the body to make it vibrate, you will end up with a weak spot where you attach whatever it is that makes it vibrate due to fatigue.

 

Are you wanting that big h.p. "rev the engine/rock the car up left to right" effect?
Maybe you could cut a hole in the drivers side floor and stand up on the pavement with your left foot when you goose the throttle....
Or, add hydraulics on the drivers side.
Careful with that 3.4 though, add too much stiffening and you might flip the car over sideways when you tap the throttle.

 

ya im talking about the left right rock when i hit the throttle i know im not gunna get what i would get with a V8 but i love when it does the rocking motion
