Does anyone make a manual valve body for that tranny? Probably
a bit of a drastic step though. Maybe a throttle stop would be a
better choice for bracket racing - certainly cheaper and could be
disabled during daily driving, unlike a manual valve body. :-)
If you're interested in trying one out, maybe I can whip something
up and send it to ya for beta testing - feel free to drop me an
e-mail if you'd like to discuss design ideas. :-)

Well, *thinking* about getting back into the saddle eventually... ;-)
Anyway, we all stopped taking your retirement threats seriously
about 3 seasons ago! ;-)

Ahhh, so *that's* what caused it. :-) I remember the incident, but didn't

:-) You're a marked man, now! "Watch out for the guy in that Red
