Can a V8 engine fit in lawn mower engine?

It is highly unlikely and impractical to fit a V8 engine into a lawn mower engine bay. A typical lawnmower has a small engine compartment designed for a compact single-cylinder or small multi-cylinder engine. A V8 engine, on the other hand, is a large and powerful engine with eight cylinders arranged in a V-configuration.

Even if it were possible to squeeze a V8 engine into a lawn mower, it would be overpowered and cause several issues. The lawn mower's frame, chassis, and drivetrain are not designed to handle the increased power, torque, and weight of a V8 engine. Additionally, the fuel consumption and maintenance requirements of a V8 engine would make it impractical for use in a lawn mower.

Therefore, it is not feasible or practical to install a V8 engine in a lawn mower. Lawn mowers are designed to have compact, efficient engines that are suitable for cutting grass and performing basic yard maintenance tasks.
