Where was that, I didnt see it?
Do you mean cause you said Joe did something with an engine that was only a few years old not decades old like I had referred to when talking about valve springs? Fail to see how you think that was correcting me TBH, you appeared to be talking about something different as a 2007 car still wouldnt have had valve springs.

Even with that 2007 one you mention, I would imagine he's still just doing hand-me-down repair work on engine, not developing them for the manufactuers like you have (intentionally or not) been implying to people it would appear, but I dont know the details so didnt comment.

I couldnt care less what he builds or not, only person who's abilities I really care much about as an engine builder are my own as thats who builds my engines.
