What is the firing order on a 1993 Chevy Silverado 5.7?

Answer 1

It's easiest to think of the engine's firing order when you look at the engine from the underside, with the oil pan removed. The connecting rods are bolted on to the crankshaft in sequence, from the front of the engine to the back. This places the odd numbered pistons on the left or driver's (USA) side, and the even numbers on the right or passenger side of the engine. When we say the firing order is 1-8-4-3-6-5-7-2, we are talking about the front-most piston attached to the crankshaft, then the rear-most piston, then the fourth, the third, and so on. This applies to all Chevrolet V8 engines, and some other brands of V8 engines, but is not universal to all V8 engines. Any repair manual would have an overhead view of the engine showing firing order.
