Sorry to hear about your kid... I'm familiar with such situations.
Some things you should consider before you do a high-stall converter: heat, gear ratio, and MPG. High-stall converters make lots of heat due to the extra slippage. You'll definitely need an aftermarket trans cooler if you go this route, or else your transmission AND your engine will likely overheat. Note that as you go up in gear ratio (i.e. from a 3.25 to a 3.73) you lose some of the benefits of a high-stall converter since the stall speed for a given converter will become lower as HP and weight go down, and as gear ratio goes up. From the experiences of friends with high-stall converters, expect to lose 2-4 MPG (even with lockup). However, one benefit will be a smoother idle.
Check out some traditional hot-rod sources to do a custom rebuild on your converter, although I'd bet it'll be pricey. Get in touch with TCI. If they can't help, they might know someone who can.

heres one for the gurus.....i cant justify the expense of converting my 535s auto to a 5 speed at this time; yet would like to maximize the potential of the 3.73 diff. has any heard of or have knowlege of a converter that offers 500-750 rpm increase in stall speed while retaining the lock up feature of 4th gear....?

thanks.....jim
