Comp Cams' Jet-Hot XER273HR grind (PN 54-444-11, retail $402.42) is advertised as a high-rpm street-strip cam that features the most aggressive lobe profiles in Comp's catalog for LS1 applications. With a power-band of 2,000 to 7,000 rpm, the cam specs in at 0.224/0.230-degrees duration at 0.050 and 0.581/0.588-inch intake/exhaust lift on a 114 LSA. As compared to the stock GM '98-'00 LS1 cam (202/210-degrees int/exh at 0.050-inch duration and 0.496/ 0.496-inch intake/exhaust lift on a 116 LSA), the Comp cam requires an efficient intake and exhaust system to realize its potential.
