look in the tech books from PJ Grady. i have them stored on my computer if you want me to mail them to you. i want to help you. i have an engine conversion and have done a little research on the trans myself, lets compare notes! ive been in contact with a man in Fla that races, street and strip, this family of trans', he has a lot of info, i just dont have my trans out to send him picks to analyze. im gunning for POS TRAC rear to handle up to 500hp. not that ill get 500, but better to build it too strong than weak. i want 300-350 with room to grow. skipper@xxxx www.sk1pper.com
