Yep, its a 1-bbl. Someone (sorry, I've forgotten who) posted that there
is a writeup in one of the current Mopar magazines. Its a pretty good
writeup too. That article estimated flow for that TB at around 600cfm, which
is pretty decent for a stock throttle body... In looking at it though,
I'm not sure how much additional performance you could get out of it. It'll
be interesting to see what can be done. One interesting thing about the
TB is that there is no throttle cable! Its "fly-by-wire", so when you press
on the gas, all you're doing is sending a signal to the computer and it
opens up the TB plate. I guess there must be a servo or something on
there.
Anyway, from reading the article, it appears that there is still much
that can be done to modify these engines. In fact, there is already a
supercharger available. But, I suspect these goodies will be few and
far between (and pricey) at first. The Mustang 4.6 guys complain about
lack of support, and they've probably got more support than we do for
our Magnums! Immagine what it'll be like for our 4.7. :-)
Personally, I don't agree with the decrease in displacement, but
perhaps the 4.7 isn't the performance death knell I once immagined. :-)
