What in the world is a T-56 Magnum?

Weird how things can change in an instant,I ended up with a 426 Hemi crate motor today and front to back TTI exhaust for it along with a Dana 60,this was not the plan but I was not able to pass it up.

That being said I may have to do this modern hemi 6-speed car but with the 67 Plymouth vert I found for $1800.


who is that guy?
