Do i have Manual valve body ??

Do you have a good bolt in rear sprague? If not I don't suggest running a manual VB. Any high perf. application is hard on the sprague. In a torqueflite that's a weak link. Install a manual VB, especially if it don't have low band apply (couldn't find it listed on either vb your looking at) and you are asking for a disaster. Look at the top of this forum at the stickies and you'll see what happened to one guy who blew his 727 to pieces. If you have a good bolt in sprague your ok with a manual VB but first make sure it has low band apply if you plan on using it on the street or be super careful to never downshift to low while coasting even at low speeds.
