15x8 magnum 500s on front of 70-72 valiant/dart/duster/demon?

Hi guys, I recently picked up a nice matching set of 4 magnum 500 rims 15x8 4.5" of backspacing with 225/60/15 tires for my 72 scamp. The rear of my car is already bbp, I am in the process of converting the front of to bbp. The rear fits very nicely; however I am concerned about the front. I picked up my caliper brackets yesterday, from a member, so I can finish putting the front back together. My question is will a 15x8 rim with a 225/60/15 tire fit on the front with bbp without any issues? I am afraid they will stick out too far, for my liking, in relation to the rear. I cannot seem to find any info on this because it appears that most people run a 15x7 and under on their cars, also leading me to suspect it is not a good idea to run 15x8s on the front. Does anyone have any experience with this? Should I just sell/trade off the two for 15x7s? Thanks guys -Mike
