Best 350 Small Block Rebuild Kit for Performance and Stock Builds

#1 · Best Overall

1. REDLINE 1986–1992 High-Performance Kit

• Weight: 22 lb

Best for: 1986–1992 one-piece-seal performance.

Why it ranks #1: Fits the 1986–1992 one-piece rear-main-seal era and lists flat-top pistons, double-roller timing, a high-volume oil pump, and multiple size options.

The 1986–1992 fitment and one-piece rear main seal configuration distinguish this high-performance 350 kit from versions listed for other block eras. It pairs high-compression flat-top pistons with double-roller timing and a high-volume oil pump for a performance-oriented overhaul.

The flat-top pistons are described as precision-machined for a 4.000-inch bore with integrated valve reliefs, tying the compression-focused choice to a specific bore detail. Double-roller timing and a high-volume oil pump add named components to the overhaul package. Multiple piston, ring, and bearing sizes are listed, but buyers must message the seller after ordering to request them; without a response within two days, standard size ships, shaping the ordering workflow.

Skip it if you have a 1993–1995 block with a 3/4-inch pump hole; REDLINE ENGINE SUPPLY's RCC350G kit names that configuration.

This fits a performance-oriented rebuild for a 1986–1992 Chevrolet 350 with the listed one-piece rear main seal configuration. Its bore-specific piston description and size-selection deadline matter when matching components to the block.

#2 · Best Early SBC Performance

2. REDLINE 1967–1985 High-Performance Kit

• Weight: 22 lb

Best for: Adjustable-size street-performance build.

Why it ranks #2: Targets 1967–1985 350s and combines flat-top pistons, double-roller timing, and a high-volume oil pump, with several piston and bearing sizes.

High-compression flat-top pistons with integrated valve reliefs give this 1967–1985 350 kit its performance focus, pairing piston choice with a stated range of available sizes. The listing also identifies double-roller timing and a high-volume oil pump for builders assembling a street-performance overhaul.

The flat-top pistons are described as precision-machined for a 4.000-inch bore and include valve reliefs, connecting the compression-oriented design to a defined bore size. Double-roller timing and the high-volume oil pump add named components to the overhaul package. Piston and ring sizes, plus rod and main bearing sizes, are offered in multiple options, but the buyer must message the seller after ordering; otherwise, the listing says standard size ships after two days without a response.

Skip it if you want a stock TBI-truck kit with a listed stock cam; LowPricedAutoParts LPAP-MKC350HP specifies 1993–1995 TBI applications.

This fits a builder planning a performance-oriented 1967–1985 Chevrolet 350 overhaul and able to specify component sizes promptly. Its listed application years and 4.000-inch-bore piston description are important boundaries when selecting parts for a particular engine.

#3 · Best Late-Model Performance

3. REDLINE 1993–1995 High-Performance Kit

• Weight: 22 lb

Best for: 1993–1995 3/4-inch pump-hole build.

Why it ranks #3: Specifies 1993–1995 fitment and a 3/4-inch pump hole, with flat-top pistons, double-roller timing, a high-volume oil pump, and oversize options.

The explicit 3/4-inch oil-pump-hole specification makes this high-performance kit identifiable for 1993–1995 Chevrolet SBC 350 applications. High-compression flat-top pistons, double-roller timing, and a high-volume oil pump position the package for builders planning a performance-oriented rebuild.

Flat-top pistons are described as precision-machined for a 4.000-inch bore and include integrated valve reliefs, providing a defined piston specification for the build. The kit also lists double-roller timing and a high-volume oil pump, tying the overhaul to named timing and lubrication components. Piston, ring, and bearing sizes are offered in multiple options, but the buyer must message the seller to request nonstandard sizing; otherwise, standard size is shipped after two days.

Skip it if you have a 1986–1992 block with a one-piece rear main seal; REDLINE ENGINE SUPPLY's RCC350E kit lists that era.

This suits a builder refreshing a 1993–1995 350 with the stated 3/4-inch pump-hole configuration and performance-oriented parts. Confirm the engine configuration and communicate size needs promptly to avoid receiving standard components.

#4 · Highest Lift Cam

4. REDLINE Stage 3 HP Kit

• Weight: 1 lb

Best for: Street-performance cam upgrade.

Why it ranks #4: For 1967–1985 350s, this performance kit specifically lists a camshaft with .480/.480 lift and flat-top pistons.

The included .480/.480-lift high-performance camshaft is the defining feature of this 350 kit, giving builders a cam-focused rebuild package rather than a basic stock-refresh listing. Flat-top pistons are also specified, while the stated fitment covers 1967–1985 Chevrolet small-block V8 applications.

The .480/.480-lift camshaft makes the kit relevant to a builder planning a higher-performance valvetrain combination, while the flat-top pistons provide a complementary piston choice for the rebuild. Its listed 1967–1985 Chevrolet small-block V8 fitment gives a defined application range to assess before parts selection. The supplied details do not enumerate the rest of the kit contents, so buyers should not assume particular bearings, gaskets, or oil-pump components are included based on this listing alone.

Skip it if you need a fully enumerated kit inventory; the LowPricedAutoParts 1993–1995 TBI master kit lists its included components.

This suits a builder seeking a camshaft-centered performance refresh for a 1967–1985 Chevrolet small-block V8. The stated year range is the key boundary; check the engine application and plan around the components actually identified in the listing.

#5 · 10:1 Flat-Top Pistons

5. REDLINE 1993–1995 HP Kit

• Weight: 20 lb

Best for: 1993–1995 high-compression rebuild.

Why it ranks #5: Designed for 1993–1995 engines with a one-piece rear main seal and 3/4-inch oil-pump hole; its listing specifies 10:1 flat-top pistons.

The stated 10:1 flat-top pistons set this 1993–1995 GM 350 kit apart for builders seeking a higher-compression rebuild. The listing also specifies a one-piece rear main seal design and 3/4-inch oil-pump hole, helping identify the engine configuration it targets.

The 10:1 flat-top piston specification gives the rebuild a defined compression-oriented direction, while the one-piece rear main seal and 3/4-inch pump-hole details narrow the relevant 1993–1995 application. The title also names HD timing, rings, bearings, gaskets, and a pump, identifying a broad set of rebuild components. Multiple piston, ring, and bearing sizes are available, but oversized selections require a seller message after ordering, so size choice is part of the purchase workflow.

Skip it if you want a stock-cam TBI rebuild with its cam and lifters listed; LowPricedAutoParts LPAP-MKC350HP specifies those components.

This suits a builder seeking a higher-compression 1993–1995 350 rebuild with the specified rear-main-seal and pump-hole configuration. Its 10:1 pistons and size-selection process are key considerations for the intended engine and build.

#6

6. LowPricedAutoParts 1993–1995 Master Kit

• Weight: 41 lb

Best for: 1993–1995 TBI truck rebuild.

Why it ranks #6: Covers specified 1993–1995 TBI truck and SUV applications and includes a stock cam, hydraulic lifters, oil pump, timing set, and expansion plugs.

A stock camshaft and hydraulic lifters make this kit a clearly specified choice for rebuilding certain 1993–1995 GM 350 TBI truck or SUV engines. Its master-kit contents extend from pistons and bearings to a full gasket set, oil pump, timing set, and expansion plugs.

The flat-top cast pistons and premium moly/chrome rings are identified for street or stock applications, while the stock camshaft and hydraulic lifters keep the listed configuration focused on a conventional rebuild. A full gasket set, rod, main, and cam bearings, timing set, and expansion plug kit gather many named parts into one package. The oil pump is specified with a 3/4-inch hole, and the listing calls for checking VIN or engine code for compatibility.

Skip it if you need a performance cam and multiple piston sizes; REDLINE ENGINE SUPPLY's 1993–1995 high-performance kit lists size options.

This is suited to a stock-oriented rebuild of a qualifying 1993–1995 TBI truck or SUV 350. Its standard-size pistons and 3/4-inch oil-pump hole define the setup, so verify the VIN or engine code before choosing it.

#7

7. Enginetech 1967–1985 Master Kit

• Weight: 1 lb

Best for: Broad-year 350 master-kit listing.

Why it ranks #7: Its title specifies 1967–1985 Chevrolet 350 fitment and describes a master rebuild kit, although the supplied listing gives few component details.

The listed 1967–1985 Chevrolet SBC 350 fitment is the clearest defining feature of this master rebuild kit, covering both truck and car applications. Enginetech identifies the product as a 5.7L OHV V8 kit, giving buyers a broad application description to compare with their engine.

Its master-rebuild title and Chevrolet 350, 5.7L OHV V8 application identify the intended engine family, while the stated 1967–1985 range and truck-and-car wording help narrow the use case. However, the supplied specifications provide no component inventory beyond the product being a master engine rebuild kit. That means shoppers cannot use this listing text alone to establish which pistons, bearings, seals, or other parts are included, making the fitment description more useful than a detailed build plan.

Skip it if you need a listed inventory of pistons, bearings, cam, and oil pump; LowPricedAutoParts LPAP-MKC350HP names those contents.

This may suit a buyer comparing a master rebuild listing for a 1967–1985 Chevrolet 350 truck or car. Its application description is clear, but the supplied information does not specify individual components to plan a complete rebuild.

#8

8. Enginetech RCC350AP Rebuild Kit

• Weight: 20 lb

Best for: Car and light-truck 350 rebuild.

Why it ranks #8: Identifies a GM 5.7L 350 car and LT truck rebuild application, but the supplied description does not detail fitment years or included components.

Car and light-truck coverage is the stated application distinction for this Enginetech rebuild kit, which is identified for the GM 5.7L 350. That concise fitment description gives buyers an engine family and vehicle-use category to check against their rebuild.

The product title identifies the kit as a rebuild for GM 5.7L 350 applications and specifically names cars and LT trucks, making those the supplied compatibility cues. Enginetech is the named manufacturer, and the listed weight is 20 pounds. No component breakdown or year range is supplied in the product details, however, so the listing does not establish which internal parts are included or define a narrower model-year application for planning the job.

Skip it if you need explicit year fitment and listed contents; REDLINE ENGINE SUPPLY's 1967–1985 kit names its range and performance components.

This is for shoppers whose GM 5.7L 350 rebuild falls within the stated car or LT-truck use. Because no years or individual components are supplied, those details are important boundaries to resolve before planning the work.

#9

9. Guardian 1969–1979 Re-Ring Kit

• Weight: 4 lb

Best for: 1969–1979 re-ring component bundle.

Why it ranks #9: Fits 1969–1979 Chevrolet 350 engines and includes rings, bearings, gaskets, and an oil pump, but is a re-ring kit rather than a full rebuild kit.

Rings, bearings, gaskets, and an oil pump are all named in this Guardian Engine Kits re-ring package, giving the refresh a broader stated scope than rings and bearings alone. Its listed compatibility is specifically for 1969–1979 Chevrolet 350ci small-block V-8 engines.

The ring, bearing, and gasket combination addresses several core parts of a re-ring refresh, while the included oil pump adds a named lubrication-system component to the bundle. The 1969–1979 Chevrolet 350ci (5.7L) fitment gives the listing a narrower application window than broader 350 kits. Oversizes are available, but availability should be verified before ordering, so buyers planning a nonstandard rebuild need to establish that option before relying on it.

Skip it if you need a kit for 1980–1985 applications; REDLINE ENGINE SUPPLY's 1967–1985 high-performance kit lists that broader range.

This suits a 1969–1979 Chevrolet 350 owner seeking rings, bearings, gaskets, and an oil pump together. Its year range is specific, and oversize availability needs checking when standard components do not suit the rebuild.

#10

10. LowPricedAutoParts 1967–1985 Re-Ring Kit

• Weight: 7 lb

Best for: Standard-size 1967–1985 refresh.

Why it ranks #10: Fits 1967–1985 small-block Chevy engines and supplies rings, rod and main bearings, and a full gasket set, but omits the broader scope of a master kit.

A focused combination of piston rings, rod and main bearings, and a full gasket set makes this re-ring kit a practical match for a 1967–1985 small-block Chevy refresh. It is listed for 5.7L/350 engines and ships with standard-size components for a 4.000-inch bore.

This package centers on the parts named for a re-ring job: piston rings, rod bearings, main bearings, and a full gasket set. Standard sizing keeps the supplied configuration clearly defined for a 4.000-inch bore, while the listing says buyers needing oversized components should message with their order. Because the product is a re-ring kit rather than a master rebuild package, its stated contents do not include a camshaft, lifters, timing set, or oil pump.

Skip it if you need a camshaft, lifters, and oil pump included; LowPricedAutoParts LPAP-MKC350HP lists those master-kit components.

Choose this for a standard-size re-ring refresh on a qualifying 1967–1985 5.7L/350 small-block Chevy. It covers rings, bearings, and gaskets, but its stated scope is narrower than a full engine rebuild kit.
