The results of the cam comparison on the normally aspirated 350 Chevy were not terribly surprising. A comparison between the XR258HR and XR282HR cam revealed that the smaller cam offered better low-speed torque production up to 3600 rpm, but lost out to the larger cam thereafter. Looking strictly at the peak values, we see that the motor produced 396 lb-ft of torque with the smaller cam to 405 lb-ft with the larger cam. Had we not included a complete graph, you'd be tempted to think they offered similar torque curves, but nothing cold be further from the truth. The big cam not only offered more peak torque, but it carried that torque production (exceeding 400 lb-ft) from 3,700 rpm to 5,200 rpm. This explains the dramatic difference in peak power. The larger cam allowed the motor to exceed 400 hp, peaking at 407 hp at 5,800 rpm.
