* 400 cubic inch (6.6L) V8: This was a common and powerful engine, but even within this engine family, the torque varied depending on the specific carburetor and other components. You'd need to find the specific output for that year and model.
* Other smaller V8 options: Pontiac offered smaller V8s in the Trans Am, again with varying torque specs.
To find the precise torque figure, you need to know the engine displacement (e.g., 400 cubic inches or 6.6 liters) and ideally, the specific model details (like a build sheet if possible) to determine the exact configuration. Then, you can search online resources or consult a 1978 Pontiac Trans Am owner's manual or repair manual.
