* 350 Engine Specifications: A "350" is a broad term. The specific engine build (cam, heads, intake, carburetor/fuel injection, etc.) drastically affects horsepower and torque. A mild 350 will be significantly slower than a highly modified one.
* Rear End Gear Ratio: The gearing in the differential dictates how many engine revolutions are needed for a given vehicle speed. A numerically higher gear ratio (e.g., 4.10) will result in quicker acceleration but a lower top speed. A lower ratio (e.g., 3.08 or even 2.73) will favor higher top speed.
* Tire Size: Larger diameter tires will lower the top speed for a given engine RPM compared to smaller tires.
* Aerodynamics: While an S10 isn't exceptionally aerodynamic, even small modifications can impact top speed.
* Transmission Tuning: The 4L60E's shift points and overall programming can affect the top speed, although its limitations will likely be the engine's power and the rear end gearing before the transmission itself becomes the limiting factor.
* Weight: Added weight from modifications or cargo will reduce top speed.
In short, a well-built, lightly modified S10 with a 350 and a 4L60E could reasonably reach speeds in the 100-120 mph range. However, a highly modified version with a powerful engine and low gearing could potentially exceed 120 mph. Conversely, a less powerful build with high gearing might struggle to break 90 mph. The car's aerodynamics and the driver's bravery also play a role. It's crucial to note that exceeding speed limits is dangerous and illegal.
