if you want to do it right and have a reliable drver, dump that stock front and rear. i've got the same car and i used a nine inch ford rear with explorer discs...up front i used a mustang II.with that much motor you will need a better suspension than stock. i also mounted a power booster with a newer corvette master in the stock location using the stock pedal. it works really well. if you need more answers e-mail me @ jswagner58@hotmail.com
