The only thing I find amazing is that the rear driveline
can possibly hold up, especially if you deliver enough
torque to "chip" into third with an obviously modified
TH400 that must have been difficult to squeeze under
the tunnel. I had a '67 Vette with the 427/435 "Trips"
and it could "chirp" into fourth, but I was running a
.488 rear. I always thought the Jag rear was pretty
tall, like a .411 or .308, but maybe they used a .512
with overdrive like the Alfa Romeo. In any event I
can't believe it (or the axles and CV joints) would
take that kind of punishment the way the old "12 bolt"
rear can, especially in that relatively heavy XJ car.
By the way, your XJ-350 would have seen nothin'
but my modified "Thunderbird" style triple tail lights.

Good luck with it.
