What front tire and rim size is best on an a body bracket car?

With the 25" tires, I've got a Milodon 8qt pan but just for safety I welded a small skid plate to the k member just in case.

I have the milodon 10 inch deep super stock pan.
I also currently have a moroso drag special 28x7.10 on a 15x3 1/2 weld wheel. I always thought the car looked over tired in the front and would like to switch to a 26 for looks, but I would be giving up an inch of pan clearance. That is my concern with this pan.
