* 5.7L: This indicates the engine's displacement is 5.7 liters. This is the total volume of all the cylinders combined.
* V8: This means it's a V-type engine with eight cylinders arranged in a "V" configuration.
* TPI: This stands for Tuned Port Injection. This was the fuel injection system used on the Corvette's engine in 1986. It's a type of port fuel injection where the fuel injectors are located in the intake manifold runners, leading to each cylinder. This provided better fuel atomization and engine performance compared to earlier carburetor systems.
* OHV: This stands for Overhead Valve. The valves (intake and exhaust) are located above the pistons and are operated by pushrods and rocker arms. This is a common engine design.
In short, the 1986 Corvette had a 5.7-liter, eight-cylinder engine with tuned port injection and an overhead valve design. This was a significant upgrade from earlier carbureted small-block V8s, offering improved performance and fuel efficiency for its time.
