I think you're missing my point. I'm not arguing that the 360 is a better or more durable engine than a 340, I'm saying that I like 360s better. If 340 cores were cheap and easy to find then I would likely go that route. Also realize that with the heads I'm talking about using I probably will not exceed the power limits of the 360. I can get Magnum 360s for dirt and LA 360 for dirt plus a dime so that's another factor.
