Swaping in a th400/350
Smartest thing you can do IMO. That's what I run and besides a great product the time Marty will take with you going over your whole combination and getting you a converter that's perfrect for YOUR combo is worth anything they charge. I got mine a ways back for $1100-worth EVERY PENNY.
FWIW, I been mid 9's for years on my th350.
Street drive too.

Sounds good to me!!! Im pretty set on the NC converter, but have been set back a bit after I just bought a 4bolt block and a new cola crank for the next motor. Should be a few more weeks b4 the 350 goes in.

I tried that on my car. I first wired it to the speed sensor on the top of the pumpkin and the speedo was WAY off. I then wired it to a wheel speed sensor on the front and it's still off. Not sure what to do other than getting a tailshaft with a hole for a speed sensor on it and a reluctor wheel to go on the output shaft.
