i have a a tranny coming out that has the front housing cracked that appears to be down from engine flex.....

i have 660+ at the wheels on the 100 shot and have opted to bump up to the 200 Shot and it appears the flex is creating some NASTY results to the tranny....

i have searched this evening but i can only find kits on the web for 98-02 f-bodies......




MY ? - does anyone know if poly mounts for the motor and tranny are available for us truck guys.....

Most f-body guys have shunned the poly tranny mounts because they cause too much vibration. Is there a way you can brace the tranny at an additional point besides stock? Not sure if a poly mount alone will solve your problem.

Make your own poly mount or use hockey pucks.

If the engine torque is indeed the culprit, you should just suck it up and go with solid engine mounts. Sure there's more vibration transmitted through the chassis, but the motor won't twist over and crack the bellhousing. You can't just do the tranny mount because that won't stop the engine from twisting and you'll end up busting the rear housing.
If you're putting out over 600 hp, you've already decided you can deal with some vibration (and ragged streetability) because your engine surely doesn't idle like stock. I installed solid engine mounts in my Chevelle (appx. 500 gross HP) and didn't notice that much of a difference.
An alternative would be to use torque rods on either side of the block, of course if you have room to rig that up. It's not as good as solid mounts, but you could keep your rubber mounts. BTW, there really isn't much of a difference between poly and solid mounts, vibration wise.
