Comp XE274HR Cam: 312 hp at 5,400 rpm, 349 lb-ft at 4,000 rpm
Next up was one of the author's all-time favorite 5.0L cam profiles, the XE274HR hydraulic roller cam offered by Comp Cams. The XE274HR cam (PN 35-518-8) featured a 0.555/0.565-lift split, a 224/232-duration split and an EFI-friendly (as well as blower and turbo) 112-degree lobe-separation angle. The author ran Crane's version of this cam in his personal 5.0L LX back in the day, and it works equally well in normally aspirated, turbo, and supercharged street combinations. The cam was chosen not for its maximum power potential, as the newer XFI cams certainly offer more power, but the XE274HR offers a near-ideal combination of drivability and power that is difficult to match. With sufficient valvespring pressure, head flow, and intake design, the XE274HR will rev cleanly past 6,500 but still provide sufficient idle vacuum, throttle response and even fuel mileage.
