Mild vs. Wild 540
Equipped with the Trick Flow Power Port heads, mild XR288HR hydraulic roller cam and Weiand Team G intake, the 540 produced 635 hp and 645 lb-ft of torque. Stepping up to the dart Pro 1 heads, custom solid roller cam and Hi-Ram tunnel ram stepped the peak numbers up to 777 hp and 681 lb-ft of torque. As is evident, the wild version of the 540 shifted the torque curve significantly compared to the mild version. Where the mild 540 produce peak power at 5,700 rpm, the wild version did so at 6,600 rpm.
