I’m getting ready to install a straight front axle and move the rear “frame rails” for a narrowed 9-inch rear end under a ’66 Falcon sedan. I’ve never done this, nor have I talked to anyone that has. I was aware of and understand the front-end alignment issues. I don’t want to overlook something that those who have done this often would know.
I’ve been watching YouTube videos and know I may need to change to front steer and relocate the steering box, etc.
I originally planned to have the body level with the rear raised for 15” large drag slicks and the front axle lowered using somewhat smaller 14-inch or 15-inch tires. This stance would put the intake manifold’s carb pad at the stock angle and the drive shaft and pinion angles should be close to stock (I hoped).
But is that best for racing? When I leave the starting line, the front of the car will rise a lot and the gas in the fuel bowls would move to the rear and the center line floats would be working at a difficult angle. Would it be better to have the car sit nose down and when it left the line the car would not be so nose high? Or am I over thinking this? As I write this, I suspect I am.
Constructive suggestions and comments will be welcomed.
