I have slowly been upgrading everything on the car. Now with the Vortech/heads/cam I am aiming for 400hp with the stock bottom end. I am waiting for the parts for the suspension upgrade to show up now. Once the bottom end and tranny can handle it I wouldn't mind possibly turning it up but more important I just want to make everything as durable and dependable as possible. As little as I know about motors, I know less about tranny's. What is there to know, stay away from and what should I plan on when I upgrade the manual I have? Do we have any 6 speed options?
