1950 Chevy 3100?

I’m building a Chevy pick-up and installing a 350/350 combo, what engine angle should I be aiming for to correspond with the pinion angle? It I level the carb mounting surface to the horizontal, will this be correct? I have also installed a Mustang 2 front suspension kit from Speedway motors,can anyone give me the Camber and toe-in measurements?
The front end is based on stock Mustang upper and lower arms.
