Among the 14 new releases, Melling offers six camshafts specifically for truck engines – an ideal choice for those looking for improved performance and easier towing in their LS-powered pickup.
Four of the new camshafts have been fine-tuned to maximize horsepower and torque in engines featuring Cathedral port cylinder heads, including the ever-popular LS1 and Ls2. The remaining four were designed for Rectangular port engines (most commonly, the LS3). The race-style Class 4 and 5 offerings for the LS1, LS2, and LS3 offer the lineup’s most “usable,” mid-range power and torque.
