Stacking aluminum lowering block?

I had 255/60/15 tires on it. This morning I swapped over to some 275/60/15 which are almost an inch taller and I like it a little better. The backspace on the Torque Thrust is only like 3 inches so they stick out a little on early B body 8.75 that is on the car. The 255's were on cop wheels which I think are 4 inch. Maybe the 275's on the cop wheels, get the front end up a bit and call it a day?
