When I pulled the engine out to put my big engine in....I could clearly see where the valves contacted the pistons on a regular basis. Did mine sound like a diesel? Umm, not at all. So that goes to show what you "think" is not always correct. It ran just fine also. 12.05. @117mph on motor with hankook radials. Why didn't it fail? My guess is I didn't give it long enough. Why didn't it run like shit? Because Im guessing contact was only at higher rpm.

I don't disagree at all with what you're saying my friend. That said, I just made an opinion based on Mike's cam replacement- not overly aggressive from what he said- that valve clearance wouldn't have been an issue unless the timing was off. If the timing was off, wouldn't he have immediately noticed issues?
