Thanks for the welcome guys:
Anthony: Seems to be a nice new product that TKO-600; nice first gear, maybe a bit more practical than the 3.27 1st in the TKOII. I was surprised to learn that Tremec is discontinuing the 3550 line.
Trularin: I'll keep the T-56 in mind, although it is a bit more expensive
MidOHasp: Here is a link to the new TKO- 500/600 page

Southernfriedcj : You're a riot !! Wouldn't you agree Alex?
Bernie Knight: Good on ya mate. Thanks for the greetings from down under.
Lowell W: I was wondering what I'd be taching with the .82 final gear with the 3.73 rear with 15" wheels and all other things being equal. I know there's a calculator around here somewhere!
RPrice: On your third SPF? You are my hero !!
Sierramadre45: You're reaching hero status !
Good night Gentlemen ... be well
