35chev/302gmc Loading the engine while in reverse will lift the right side(pass) of the engine

solidaxel With someone watching the engine put it in reverse with your foot on the brake and give it a little throttle and see if it moves up off the drivers side motor mount. My 69 Camaro always did after the kids drove it !!!!!!!!!!!!!

DOUBLEDICK Try the neoprene motor mounts and trans mount.I switched to them after breaking 3 drivers side mounts even broke the ear off the last non torque over mount.They put a Little more noise into the interior but they are quieter than a solid mount. The trans noise is probably a broken transmission mount.

jimfulco I don't know if they had fixed the motor mount problem by 1970, but you can look at your driver's side mount and see if there is an interlock mechanism built into it. If not, and the mount has failed (either broken or unglued), it can cause the engine to lift off the mount when you start off from a dead stop, and if you're taking a left at the same time, the throttle can open by itself, causing unintended acceleration, burning rubber, annoyed bystanders & police, etc. They recalled a few million cars for this problem back around 1970 or 1971, and they basically tied the left side of the engine to the frame with a steel cable. My '72 Nova came from the factory with the interlock mounts, but I don't know if they'll work on a car that came without them unless you change the frame brackets also.

Thanks for the replies

This is a 1970 Nova SS 350/350. Thanks for the replies. I have a bad habit of jumping to the worst conclusion and somtimes I tend to overlook the obvious.

jimfulco Might also check your motor mounts to see if one's lifting under torque.

I feel a clunk when I take off from and turn sharp at the same time.

I feel a clunk from the trany (seems like) when I take off while making a sharp turn. What could it be? Does anyone have a good idea of what this could be. Turbo 350.
