Here's a more detailed explanation:
1. Acceleration: A higher numerical gear ratio, such as 3.73, would provide stronger acceleration from a standstill and at lower speeds. This is because higher numerical gears multiply the torque output of the engine, resulting in quicker wheel acceleration.
2. Top-End Speed: A lower numerical gear ratio, such as 3.55, would allow for higher top-end speeds. This is because lower numerical gears reduce the rate at which the engine RPM increases for a given increase in vehicle speed.
3. Fuel Efficiency: Fuel efficiency tends to be better with lower numerical gears, as the engine operates at lower RPMs while cruising at highway speeds. However, the difference in fuel efficiency between 3.55 and 3.73 gears is likely to be minimal.
4. Other Considerations: In addition to the desired performance characteristics, factors such as tire size, transmission type, and overall vehicle weight should also be taken into account when selecting the optimal gear ratio.
Ultimately, the best gear ratio for your 1967 Camaro RS with a 383 stroker engine will depend on your personal driving preferences and intended usage of the vehicle. It may be helpful to consult with experienced mechanics or performance enthusiasts to determine the most appropriate gear ratio for your specific setup.
