I have a Carbed LT1 with a T56 6-speed transmission. I have it in there now with a motified T350 crossmember it is really rough too. Will the T400 crossmember work? I have heard that it will but am unsure. Please help if you know anything about this.

 

as an educated guess, I would say no but I have no actual data to back that up so hopefully someone with actual experience will chime in
