Camshaft & 83mm Piston Complete Gasket Top End Rebuild Kit
Top-end rebuild kits like this are best for ATV or motorcycle engine enthusiasts replacing a worn cylinder, piston, and gasket set in one purchase. The kit combines a camshaft, 83mm pistons, and gaskets to restore compression and timing accuracy. Suitable for Yamaha Warrior, Raptor, and Bruin models from 1987 to 2006, this option suits riders who want a one-and-done top-end refresh. Limitations include verifying exact bore and compatibility with your engine variant before purchase. Best for hands-on builders focused on long-term reliability and performance restoration.
Camshaft & Piston Top End Kit For Yamaha 350
Best for riders seeking a complete top-end refresh on Yamaha 350 variants, this kit emphasizes a balanced approach to restoring power with reliable top-end components. It’s a practical pick for enthusiasts who want to minimize aftermarket part mismatches and streamline installation. A caution: confirm exact model year alignment to avoid bore-size mismatches during assembly.
DNJ EK3101M Master Engine Rebuild Kit
DNJ EK3101M is a broad-spectrum rebuild kit designed for 1967–1980 Buick, Chevrolet, GMC, Oldsmobile, Pontiac 5.7L V8 engines. It combines pistons, rings, bearings, cam bearings, a gasket set, a stock camshaft, lifters, timing components, and an oil pump. Best for classic car restorers who require a comprehensive, all-in-one solution. Choose this if you are restoring a vintage GM 350 and favor a complete component package; beware of potential need for additional machining depending on engine condition.
LowPricedAutoParts GM 350 Master Rebuild Kit (1993–1995)
This kit targets 1993–1995 GM 350 5.7L small-block engines, including premium rings and standard-size pistons, bearings, cam bearings, a full gasket set, lifters, timing gear, and an oil pump. It’s best for street and light off-road use where standard bore and stock components are suitable. A caution: verify VIN and engine code to ensure exact compatibility with your truck or SUV model; do not assume universal fit across all 5.7L Chevy engines.
LowPricedAutoParts GM 350 Master Rebuild Kit (1967–1985)
This kit is tailored for classic 1967–1985 GM 350 builds, featuring standard pistons, rings, bearings, a cam, lifters, a timing set, and an oil pump suitable for 2-piece rear main seal blocks. It’s ideal for enthusiasts restoring vintage small-blocks seeking a complete rebuild solution. Limitations include the need for machining checks for worn blocks and the fact that it is not meant for engines requiring aggressive performance upgrades or non-standard bore sizes.
TH350 Transmission Raybestos Stage 1 Deluxe Kit
While not an engine kit, this transmission rebuild package suits Turbo 350 transmissions rebuilt with high-quality Raybestos friction plates and a complete gasket and seal set. Best for rebuilds where the transmission is the limiting factor in performance, offering durable components that align with professional installation standards. Choose this if your project includes a transmission refresh in tandem with an engine rebuild; avoid this if you only need engine internals.
Buying Guide
What should you consider when choosing a complete 350 rebuild kit? Start with bore size compatibility and whether you need a full engine kit or a top-end kit. For older GM small-blocks, confirm rear main seal type and block design to ensure proper bearings and gaskets. If you own a Yamaha ATV or motorcycle, prioritize top-end kits that include pistons, rings, and seals matched to your model year. Inspect camshaft compatibility with your stock cam or the need for a different grind. For transmissions, recognize whether you need a separate kit or a combined package with engine parts.
Ease of installation matters. Some kits assume machining or honing is already completed; others are more “drop-in” but still require precision assembly. Consider your mechanical capacity and whether you’ll source extra components like head gaskets, valve seals, or timing chains separately. Store your engine’s bore, stroke, and clearance specifications to avoid mismatches during assembly. Finally, verify model-year alignment, VIN-based code, and application notes to ensure the kit matches your exact engine family.
FAQ
- What is a master rebuild kit? A master rebuild kit typically includes pistons, rings, bearings, gaskets, a cam, lifters, and timing components, providing most parts needed for a full engine overhaul.
- Do I need machining with these kits? Some engines require machining or blueprinting for proper clearances. Check bore size, crank journal dimensions, and piston-to-wall clearance before assembly.
- Can I use a GM 350 kit on any 350 engine? No. Verify bore size, rear main seal type, and block design to ensure compatibility with your specific engine family and model year.
- Is a top-end kit sufficient for performance restoration? For many ATV or small-block rebuilds, a top-end kit can restore compression and power. A full engine kit is needed for a complete overhaul.
- Can I replace only the transmission parts? If the transmission is the limiting factor in performance, a dedicated rebuild kit (like a TH350 kit) is appropriate. Engine-only kits won’t address transmission wear.
