LSX Swap Questions

[Mike Holleman]

Glad to know that I'm not the only one this has been a surprise for. As to Chevelle tunnel surgery, have people found it better to split the tunnel in half and widen it with a filler piece, or to simply replace the tunnel altogether?

Having done several installs of this type, there is no right and wrong way. If you are buying your Tremec from an outfit like Keisler, they can provide a complete kit that will include directions and templates as to what you remove and what the replacement part will look like. I've done two of Keislers TKO500 installs in Chevys. One in a 55 and it required no tunnel mod except a hammer reshape. I did a 69 GTO and it required removing the upper part of the tunnel and adding a piece of sheet metal. They provided a template and it was an easy fit. I put a T56 in my Elky but it is a very different beast. I was working with new floor pans and the body is sitting on a Schwartz chassis that is solid mounted to the body and the engine is basically a solid mount. In other words I did not have to account for drivetrain movement. Highly recommend the folks at Keisler.
