Ebay GT45 + 5.9 Magnum + E85 blow thru

Have you heard any successful stories with cal tracs? Are you running a drag radial or just a street tire?
I'm running 295/60/15 drag radials, original slant 6 springs, clamped at the front, sliders and 3 way adjustable drag shocks. Drag shocks on the front and v8 torsion bars.
