Thats why it caught my eye,it was the first 4.3 I saw with splayed valve heads.I talked to the owner,he said that they changed it from even fire to odd fire by changing the crank,ignition and electronics.When I heard it go by it was turning some awesome rpm.Way more than an even fire is capable of.If you think an even fire 4.3 runs ruff,an odd fire idles like a washer machine with one leg missing.
