Suggestions for increased caster angle.

[SShep71]

Im makin a protouring 70 chevelle and I am creating and fabing the chassis,suspension,and driveline. I am thinking about in creasing the caster angle 1.5-2 deg from -1° to something around -2.5° to -3°. I am going to fab the upper and lower control arms for this adjustment. Do you think I should go more or less. I was planning on going to a closer ratio steering box, and maybe changing the steering arm length.
Any suggestons you can help me with are greatly appreciated. I am getting as much input before I even start drafting the arms.


Thank You
