Can I use a factory M6 crossmember for a TH400 swap? Or do I need an aftermarket crossmember for this swap? Thank you in advance.

 

i have no idea as far as the placement on the mount (have heard it fits but have also heard it didnt haha) but you will need either a short torque arm or to fabricate a torque arm mount somehow

 

Call Eric @ MWC and he will set you up.

 

Yes you can.

Just curious are you still running your stock bottom end lt1 set up, trying to break 10's?

 

Cool.
No longer running the ole LT1. A pushrod let go and blew a piston during a dyno session over the Summer. I was going to build a 383 or 396 stroker, but decided to go LSX. Now planning on running a TH400 with the new build.
