2004R's can be built (with aftermarket parts etc) to similar strength's as the
700's are (with aftermarket parts etc)...and most last "ok" up to about 500
ft/lbs or so with traction...there are other issues however...

Remember that TH-350's can be built stronger than either OD
trans...Glides...400's...and 4L80E's stronger yet...

If it's a combo with a "streetable converter" and a Super Ram'd BB for example
that makes that kind of torque off idle and you're runnin' slicks you're gonna
shock the trans at launch a lot harder than say a turbo six which makes it's
power higher up the rpm scale...

What's the rest of your package Tom...it seems like a miss match with a 10"
converter mated to a TH-350 and a 2.73 axle...though probably not a problem if
you've got a "Mountain Motor" in there...(:>)

As a note...for at least the TH-400's (maybe the TH-350's also) you can get
custom gear sets...somebody modify's the 2004R and 700R4 first and second
gears for use in TH-400's etc...you can (or could at least) get the following
for the TH-400...I have no idea about their reliability...

a) 3.06...1.57...1.00

b) 2.74...1.57...1.00

Selection "a" would make more sense to me with a 2.73 rear gear and a three speed...

For a race car sure...for a fast street car maybe a overall ratio of 9.5/1 to
10.5/1 in first to avoid blowing away the street tires too badly...

See you...
