It should fit without cutting up your tunnel. I believe the T56 is blockier (if there is such a word) than the 4l80E yet it fits fine. However, from what I have read, the 4L80E is a heavy trans and will need extra reinforcement on the trans Xmember

I am working on this now. I have a LQ9 engine and a 4l80e transmission. I am trying to figure out the best position to mount the engine and if I can retain the use of the front brackets for the ac, alt. and ps. I think the trans will fit fine. I am planning on using the 400 trans crossmember in my car. The car is a 1978 trans am. I also am going to try the pacesetter headers. I talked to BRP about their kit for this car and didn't like the price or cutting the trans tunnel. I should have the engine and trans installed in a couple of weeks. Send me a message if you want any pictures.
