The ground work looks pretty good. It doesn't show what he's using as a final drive, I sure hope it's not the TR rear. Judging from the finned brake drum I think it is.
I'm a big fan of this conversion when done well. If it's done only to go in a straight line your only using half of the cars potential. If the right engine & driveline are mated to an improved suspension , brake & wheel package, then you have a real world class screamer.
