What is the firing order on 87 Chevy?

The firing order for a 1987 Chevrolet depends entirely on the engine. Chevrolets in 1987 used a variety of engines (V6, small-block V8, and large-block V8). You must specify the engine size (e.g., 2.8L V6, 305 cubic inch V8, 350 cubic inch V8, etc.) to get the correct firing order.
