This was a long time coming. This 1973 Mach 1 with a 521 stroker motor has seen the track before. But with this engine she has never been able to get any traction at the starting line. A full rear Calvert Racing Suspension has always been in the cards for this ride, it was just a matter of getting the funds together to finally make the purchase. As always the Torque Works crew was there to lend a helping hand and get the new mono leaf spring set, traction bars, and 9 way adjustable shocks installed. And man she hooks a lot better now.
