Rear end selection help and opinions

I would use 3.70 r&p with a 28" tire for cruising and a 26" tire for drags or spirited driving or 3.55 r&p with any tire around 26-27" tall . The bowtie boys call it :"350/350 with a 350 turbohydro with a 3.55 r&p with a 26" tire , lol . the system works for the granny broomstick crowd .
