Wheel and tires question

Hi everybody! I hope someone can help me...I plan to buy new SS Chevelle wheels for my 70 SS396. It now has 14", and I plan to go 15". The question is, what would look better - 15x7 all the way around or 15x7 in front w/ 15x8 in back? And what size tires for front and back? My car doesn't have power steering [yet], and the older I get the harder it is to steer the beast! Thanks for your help!

I run 15X7 front and 15X8 on the rear of my 69.
