Is A Odd Fire Firing Order 123456 ????? If Not What Is It ? Thanx

 

[turbodave231]

Every buick V6 since 1977 is an even fire engine. It fires a cylinder every 120 degrees of crank rotation. The rod journals for each pair of cylinders do not share a common crank pin. Even fire cranks have their crank pins split (or splayed).

The early Buick V6's were odd fire because each pair of cylinders in the vee used a common crank pin. This causes the firing to take place at 90-150-90-150-90-150 degrees of crank rotation.

Here is a good site to explain more:
