Best Answer

2.8L V6 (173 CI) Engine

Plugs: Champion RV12YC Gap: .045 Timing: 10º BTDC (see below) Firing Order: 1-2-3-4-5-6

The odd numbered cylinders are on the passenger side, front to back. The even numbered cylinders are on the driver side, front to back. The distributor rotation is clockwise.

This design may seem odd to those who are familiar with Chevy engines, but this is the true firing order and cylinder layout for all 2.8L V6 (173 CI) Chevy engines.

Simply Check the INTAKE MANIFOLD.. the firing order is embossed on it near the throttle body
