How much oil does a 1964 Chevy 327 take?
For the 1964 Chevrolet 327 small-block V8, the standard oil capacity is about 5 quarts with the oil filter installed; roughly 4.5 quarts if the filter is not included. Real-world results can vary slightly depending on the oil pan and filter configuration, so always verify the level with the dipstick after an oil change.
Standard capacity for the 327 small-block
Most factory data from that era indicate 5 quarts total capacity with the filter installed. The engine’s internal capacity without the filter is about 4.5 quarts, since the filter and housing also hold oil. In practice, many owners fill to about 5 quarts during routine changes; check the dipstick for the final level.
Variations and considerations
Oil pan design and filter type can shift the actual amount that must be added. For example, a deep-sump or high-capacity pan adds a small amount of capacity, while cartridge vs. spin-on filters can differ slightly. Corvette and full-size Chevrolets using the same basic engine usually share the same ballpark numbers but variations exist. Always refer to the specific vehicle's manual or factory service bulletin for exact figures for your car's configuration.
Common configurations in 1964 models
Corvettes with the 327 V8 generally follow the same basic capacity, but some high-performance or racing-oriented setups may use different pans or relief features, resulting in minor differences. In standard street configurations, plan for about 5 quarts with filter installed.
How to fill and verify
Practical steps: Warm the engine, drain old oil, replace filter, add oil gradually to the 5-quart target, run the engine briefly, then park on level ground and recheck with the dipstick. If the reading is below the full mark, add small increments and recheck until full line is reached. Avoid overfilling as it can cause foaming and damage.
Summary
For the 1964 Chevy 327 small-block, expect about 5 quarts of oil with the filter installed and about 4.5 quarts without. Variations can occur due to pan design or filter type, so always verify with the dipstick and consult the vehicle’s manual for your exact configuration. Consistent checking and using the recommended oil grade are essential for engine health.
How much horsepower does a 1964 327 engine have?
365 hp
The engine was updated in 1964, upping the power to 365 hp for the top-dog 1964 Corvette 327 Engine. A 1963 L76 is not the same as the 64-up L76. This is the casting number on the driver-side rear of the block.
What kind of oil does a Chevy 327 take?
For a Chevy 327, use a conventional or high-zinc oil with a viscosity like 10W-30 or 10W-40, depending on engine wear and climate, and check the owner's manual for the specific recommendation. Modern oils with lower zinc can cause premature camshaft wear, so oils like Valvoline VR1 or a diesel oil like Rotella 15W-40 are often recommended for a high-performance, flat-tappet camshaft engine.
Oil types and weights
- 10W-30 or 10W-40: These weights are a good starting point for a 327 engine.
- 10W-40: is a good option for older engines or hotter climates.
- 10W-30: is a lower viscosity oil that can provide better flow at cold starts and improve engine efficiency.
- Diesel oils (e.g., 15W-40 Rotella): These are often recommended for engines with flat-tappet cams because they have a higher level of zinc, which is crucial for protecting the camshaft.
- High-zinc oils: These are crucial for preserving the flat-tappet camshaft found in many 327 engines. Be cautious with modern synthetic oils that have low zinc content, as they can lead to cam damage.
- Racing oils: Oils like Valvoline VR1 are designed for high-performance engines and also contain the necessary zinc additive.
Important considerations
- Engine wear: If your engine is older or has a lot of miles, a heavier weight oil like 15W-40 might be a better choice to help manage oil leaks and burning.
- Camshaft: The flat-tappet camshaft in a 327 engine requires an oil with a high level of zinc to prevent premature wear.
- Oil filter: Remember to use a quality oil filter when changing your oil.
- Oil capacity: A Chevy 327 engine typically requires about 5 quarts of oil, including the filter.
- Oil pressure: If your oil pressure is low, it could be due to excessive bearing clearance, a weak oil pump bypass spring, or too much material being honed from the oil pump. It is best to consult with a professional to diagnose the cause.
What kind of oil does a 1963 Corvette 327 take?

How many quarts of oil does a 327 engine take?
A Chevy 327 engine typically has an oil capacity of 5 quarts when the filter is changed. For some specific applications, like high-performance Corvette engines, the capacity might be slightly different, but 5 quarts is the general standard.
- For a typical 327 engine: 5 quarts (with a filter change) is the standard oil capacity.
- For some high-performance or specific applications: Check the owner's manual or a reliable source, as capacity can vary. For example, some engines may require 6 quarts.
- During an oil change: It's best to add about 4.5 quarts, run the engine for a short time to build pressure, shut it off, wait for the oil to settle, and then check the dipstick to add the final amount needed to reach the "full" mark.
