I'm getting ready to go through a C5. I plan to put it behind a 347 stroker. Not sure yet where I'm going with the motor as far as cam heads that type of thing. But I would like to put the right stuff in the tranny so that it will hold up to a healthy combo. This will be my first auto build. And I would like to get it right the first time. It's going in a 87' notch back so it won't be a heavy car.
