The engine and the K member were designed to support the engine. If you want to reduce the movement of the engine use stiffer motor mounts. I have seen busted bell housings where they were tied to torque limiters.
I did find that the urethane motor mounts improved the shift performance and made the front of the car feel stiffer.
I also put a brace between the K member and the radiator support tied to the sway bar mount. I can't say for certain I can feel that.
You will feel a little more NVH with the brace and torque limiters but if your car was like mine and didn't come with a K memeber brace to start with it is worth it. I've also got a set of Prothane engine mounts and the SS braided clutch line. My problem has never been the 2-3 just the high rpm 1-2 wants to grind a little.
Ya lower rpm fine..... 5500 and up forget it I can't hit third or fourth... I have a ram clutch and a billet flywheel would grind now cant put into gears at high rpm. I also have a hurst was thinking about putting the stock back just to see if that helps. I have heard motor mounts like u said. Thx for your help guys.
