Full manual valve body, yea or nay?

Mostly track car.. hell yes. Street car nope. A good shift kit with the right 1-2 spring, get the line pressure correct and a 3500 stall converter. Then if you want to manual shift you still can. Best of both worlds.
It's been a few years since I put the combo together, but I believe it may even be closer to a 3800 stall
