Sum-8712 is the part number for the Pro Ls stage 1 truck swap cam and would be a good option. It’s a drop in cam, but there’s a .550 lift/ls6 spring version (Sum-8719) if you are willing to spend another $80 on springs to extend the rev range. There’s also a drop-in tow max-torque version (Sum-8718) if you are doing more wheeling than anything else and looking for maximum torque in the idle and midrange...or to smoke the tires.
