Purpose-built for Small Block Chevy 262 283 305 307 327 350 383 and 400 engines from 1958 to 1998 — the most complete COMP Cams 12-432-8 Xtreme Energy retro-fit roller cam kit available — one order one shipment zero guesswork.
+45 TO +60HP – THE ULTIMATE STREET STRIP WEAPON FOR CLASSIC SMALL BLOCK CHEVY – 230/236 Duration at .050", .510"/.520" Asymmetric Valve Lift, 110 LSA, 2,200–5,800 RPM Operating Range. Grab this retro-fit roller cam because it is the ultimate street strip weapon for classic Small Block Chevys — delivering a hard-hitting muscle-car lope and up to 60 extra horsepower without sacrificing your power brakes. Bridges the gap between basic street cams and radical race profiles — forcing vintage small blocks to breathe at peak performance levels and delivering modern triple-digit volumetric efficiency to early carbureted setups. True peak power sweet spot lives between 3,000 and 5,600 RPM pulling fiercely across the track before running out of breath around 6,000 RPM.
BILLET STEEL TRUE DOUBLE ROLLER TIMING SET – Heat-treated billet steel sprockets and a heavy-duty dual-roller chain deliver rock-solid cam timing accuracy and long-term durability that stock single roller timing chains simply cannot match on any performance SBC retro-fit roller cam build. Eliminates timing stretch and delivers precise stable cam timing under aggressive use — keeping the Xtreme Energy XR282HR-10 cam profile locked in perfectly mile after mile. This is the hardware that separates a proper retro-fit roller SBC cam swap from a basic parts swap — critical for maintaining the aggressive mid-range power delivery this cam was engineered to deliver.
PREMIUM REDLINE RETRO-FIT LINK-BAR HYDRAULIC ROLLER LIFTERS – ELIMINATES WIPED LOBE FAILURES – Premium Redline Performance link-bar retro-fit hydraulic roller lifters drop in with no machining no dogbones and no spider trays required — turning flat-tappet SBC blocks into roller-ready powerhouses without any block modification whatsoever. Upgrading a vintage 1958–1998 flat-tappet engine block to this link-bar hydraulic roller setup completely eliminates the anxiety of wiping out lobes — the modern roller lifter wheel tracks seamlessly across the cam face freeing up horsepower stolen by old-school mechanical friction. Heavy-duty link-bar design provides stable roller tracking excellent lubrication control and long-term durability perfectly matched to the aggressive .510"/.520" lift profile.
BRUTAL TIRE-SHREDDING MID-RANGE SURGE – VIOLENT PULL FROM 2,500 TO 5,800 RPM – This cam features incredibly fast opening ramps that snap the valves open — delivering a brutal tire-shredding surge of mid-range torque the split second you climb past 2,500 RPM. Slightly soft below 2,200 RPM due to the race-level duration — then transforms into an instantaneous hair-trigger explosion the exact millisecond you floor it in the mid-range. Must be paired with a 2,500+ RPM high-stall torque converter and performance rear gears of 3.42 to 3.73 or deeper to skip the lower transition zone and flash directly into the aggressive mid-range powerband.
AGGRESSIVE HARD-HITTING MUSCLE CAR LOPE – AUTHORITATIVE HOT-ROD PRESENCE – The tight 110 degree LSA paired with large duration numbers delivers a highly distinct mildly rough and choppy muscle-car lope at idle — an undeniable hot-rod presence at stoplights dropping a rhythmic rumble through the exhaust pipes while settling into a reliable idle when warmed up. Still manages to preserve enough engine vacuum to safely assist factory power brakes without requiring secondary vacuum pumps in healthy builds — the ultimate balance of aggressive street strip sound and real-world daily drivability.
RETRO-FIT INSTALLATION NOTES – VERIFIED FITMENT – Early Gen 1 small blocks require a front timing cover thrust button and wear plate to prevent the cam from walking — stock O.E. valve springs cannot be used and upgraded valve springs are required for all applications. Requires a melonized distributor gear. Needs intake headers 2,500+ stall converter and performance rear gears of 3.42 to 3.73 or deeper for best performance. Compatible with Small Block Chevrolet 262 283 305 307 327 350 383 and 400 cubic inch V8 engines from 1958 to 1998. Fits Camaro Chevelle Nova Corvette El Camino Impala Monte Carlo C10 C20 K10 K20 trucks and all other GM vehicles equipped with Gen I Small Block Chevy V8 engines.
