The COMP CAMS Chevy V6 4.3L Hi-Tech Roller Timing Set 87-90 (part number 3136CPG) is a double-roller timing chain assembly engineered for Small Block Chevy and GM V6 engines from 1987 through 1990. This timing set replaces the original cam-driven timing chain with a precision-built system designed to maintain accurate valve timing under sustained rpm and engine stress, critical for both stock restorations and performance upgrades on these classic Chevy V6 platforms.
The kit features a double-roller design that reduces friction and wear compared to single-roller chains, allowing tighter tolerances and more consistent timing throughout the engine's operating range. The combination of cast iron and billet steel construction provides durability across the temperature and load variations typical of V6 engine operation. The hi-tech engineering approach ensures that valve overlap and timing events remain precise, which directly impacts combustion efficiency, emissions control, and overall engine reliability—especially important for 1987–1990 model years where OEM timing components may have accumulated wear or stretch.
This timing chain set is the correct choice for owners restoring, rebuilding, or refreshing Small Block Chevy V6 engines in late-1980s vehicles. Whether you're performing a complete engine overhaul, upgrading an aging power plant, or ensuring a rebuilt engine performs at OEM specification, this COMP CAMS timing set provides the precision and longevity required. The kit weighs 2.93 lbs and is engineered as a complete system, simplifying installation and eliminating the guesswork of matching individual components.
COMP CAMS has built its reputation on cam and valve train components that meet the demands of both OEM restoration and performance engine building. The hi-tech roller timing set represents the modern standard for these classic V6 platforms, offering a clear upgrade path from original timing chains that may be stretched or worn after three decades of service.
