I'm looking at Tom's Valiant and unless I missed he's running stock A body discs up front and Mustang rear discs out back and killing lots of "modern" iron.
I guess if I ever plan to hit the Silver State Challenge or try to beat my personal banzai run from San Diego to Tucson's time (4.5 hours to cover 400 miles) I don't need much bigger than I have.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
