BUYING GUIDE
From my perspective as an electronics expert who understands system integration, selecting the right flywheel or flexplate is about ensuring optimal mechanical and, by extension, electrical system harmony. It’s not just a spinning disc; it’s a critical component for engine balance, starter engagement, and power transfer. Prioritizing value and long-term cost-effectiveness means making informed choices based on key factors.
-
Balancing Act: Internal vs. External:
- Many Chevy 350s (especially earlier models) are internally balanced. This means the crankshaft, pistons, and rods are balanced as a unit. For these, an internally balanced flywheel (like the JEGS option) is essential to maintain engine harmony and prevent damaging vibrations.
- The Chevy 400 small block and some later 350s are externally balanced. This requires a specific flywheel or flexplate with a weighted counter-balance to achieve overall engine balance. Using the wrong type will lead to severe vibration and potential engine failure. Always verify your specific engine’s balancing requirement before purchasing, as this is a non-negotiable factor for engine health. Getting this wrong is a costly mistake.
-
Material Matters for Durability and Value:
- Most street applications will be well-served by cast iron or high-quality steel flexplates. These materials offer a great balance of durability and cost-effectiveness.
- For higher horsepower or racing applications (where SFI approval might be a factor, though not always for 168 tooth flywheel chevy 350 setups, especially in street cars), chromoly steel is preferred for its superior strength and lighter weight. However, these often come at a premium. For a budget-conscious approach, ensure the standard steel or cast iron is of sufficient grade to withstand your intended use to prevent premature failure and the need for costly replacements.
-
Consider System Compatibility and Hidden Costs:
- Always verify the tooth count (168 in this case) to ensure compatibility with your starter motor. An incorrect tooth count will lead to grinding or non-engagement.
- If using an automatic transmission, pay close attention to the torque converter bolt pattern on the flexplate. Options with dual patterns (like the Speedway Motors unit) can save you money and hassle by accommodating a wider range of converters.
- Think about the whole system. A cheap flywheel might require a custom starter or special bolts, negating any initial savings. Look for bundled solutions (like the flexplate with HP bolts) that provide a complete, compatible package for better value.
Common Questions About 168 Tooth Flywheel Chevy 350
What Is the Purpose of a 168 Tooth Flywheel Chevy 350?
The 168 tooth flywheel chevy 350 serves several critical functions. In manual transmission setups, it acts as a rotating mass to smooth engine power delivery, provides a surface for the clutch to engage, and features gear teeth for the starter motor. For automatic transmissions, a flexplate (the automatic counterpart) serves as the starter ring gear and connects the engine to the torque converter. The 168 teeth are specifically designed to interface with corresponding starter motors.
How Do I Know if My Chevy 350 Needs a 168-Tooth or 153-Tooth Flywheel/Flexplate?
The tooth count largely dictates the diameter of the flywheel/flexplate and, consequently, the starter motor type. A 168-tooth unit is larger in diameter (typically around 14 inches) and generally used with staggered-bolt pattern starter motors. A 153-tooth unit is smaller (around 12.75 inches) and uses a straight-across bolt pattern starter. The easiest way to determine which you need is to physically measure your current flywheel/flexplate diameter or inspect your bellhousing for the starter bolt pattern.
Can I Use a 168-Tooth Flywheel on a Chevy 350 That Originally Had a 153-Tooth?
Generally, no, not without significant modifications. The bellhousing typically dictates the starter motor bolt pattern and depth, which are specific to either a 153-tooth or 168-tooth flywheel/flexplate. Trying to interchange them usually results in the starter not engaging correctly or even physically colliding with the flywheel/flexplate. You must match the flywheel/flexplate to your bellhousing and starter setup.
What Does “Internally Balanced” Versus “Externally Balanced” Mean for a Chevy 350 Flywheel?
“Internally balanced” means all the necessary counterweights are integrated into the crankshaft itself, so the flywheel/flexplate does not need additional weights. Many early Chevy 350s are internally balanced. “Externally balanced” means the crankshaft requires additional counterweights on the flywheel/flexplate and/or harmonic balancer to achieve overall engine balance. The Chevy 400 small block and some late-model 350s (e.g., 1986-up one-piece rear main seal engines) are externally balanced. Using the wrong type will lead to severe, engine-damaging vibrations.
Is SFI Approval Important for a 168 Tooth Flywheel Chevy 350?
SFI (Specialty Equipment Market Association) approval is a safety certification primarily for high-performance and racing components. It indicates that the part has met rigorous testing standards for strength and integrity, crucial for preventing catastrophic failures (like a flywheel exploding) at very high RPMs. For most street-driven Chevy 350s, SFI approval is not strictly necessary, and non-SFI approved flywheels/flexplates are perfectly safe and cost-effective. However, if you plan on drag racing or high-RPM track use, an SFI-approved component is a wise safety investment.
