Hi,
I have two suggestions - well three really.
1. Contact John's Conversions and see what they recommend. After all, they
sell conversion kits for Chevy 350 into all sorts of applications. They'll
try to talk you into a Buick V6 conversion, but they might be a resource.
Particulary if you talk to someone with a technical background.
2. Contact Woody Cooper of The Wedge Shop and see if he has a
recommendation. Woody is _the man_ with TR8 info.
3. The do-it-yerself approach: go to a speed shop and corner weight the
car. With a few calculations and the corner weights of the car, you should
be able to "figure" out the correct spring rates. For instance. if each
front corner wieghs in at 500 pounds and you pull of the stock springs and
identify that they are 400 lb/in rating, moving up to 500 lb/in will change
things dramatically. Keep in mind: this is a gross under simplification of
the theory involved in changing your springs. Also keep in mind that small
chages in the spring rate can change the handling a lot, so don't "move up"
in big jumps - try small jumps first. This is why corner weighting will
help - it is a way to eliminate the guess factor in the task. Any competant
spring shop can wind you some springs... it's just a matter of money.
Note: TR8's have a "anti-dive" kit to fix some handling problems for TR8's.
A lot of TR7 guys put these on even if they are stock TR7's. Talk to Woody
Cooper about this.
There's also a Wedge mail list where there may be more folks who know about
these things... you might want to join that mail list.
Good luck either way.

TR6's - no TR7's, yet.
