Reply to "cam firing order swap"

George PAdmin.

Julian, you're on the right track.

The problem with the older firing order was 1 - 5, the force of combustion acts on the same connecting rod journal one after the other. The later firing order moves the problem to the rear of the motor, to 4 - 8. There is supposed to be an advantage to that.

But swapping one Windsor firing order for another is no big deal really. Like John said, enthusiasts have done it for years.

The hoopla about the SBC firing order is a new thing, the latest big news, go spend your money on a new cam. While the Windsor firing issue is supposed to improve the durability of the motor, the new Chevy firing order is supposed to make more bhp. Comp Cams is grinding new cams. I have no idea if any of the other cam makers are do so as well. I'm sure thats what Bill had referred to.
