Im still not sure, Ive replaced both motormounts and the subframe bushings with aluminum ones but I still have noticeable engine movment, granted its better that it used to be, but when compared to other SHO's something isnt totaly right. I understand these cars will never attain perfection, but is there anything I may have missed, is there any other area on the car that holds the engine in place? Do they offer stronger motormounts for an ATX SHO?

You could install a torque strap to limit engine movement. I read somewhere that you can wrap a chain around the front exhaust manifold and attach the other end to the sub-frame. You can use a turn buckle to make adjusting it easier.

Secure it to the exhaust manifold? eek! I'd attach it to the block somehow. I seen this mod over at the TCCA and have wanted to do this.

I have a chain on the front manifold on my V8, it is secured to the subframe. No problems and does an excellent job. If the chain is secured so that it is straight down and tight around the manifold then there are no stress issues i wouldn't think. I leave about a 1/4" of slack in the chain after the manifold.

I was just laying under my V6 for the last day and a half and looked at it too. It looks like it could be done on it easy enough. Straight below the manifold are some holes in the subframe. Connect a chain around the manifold just above where the Y pipe attaches and the run a 3/8" bolt through the subframe.
