I think at the end of the day neither of you two guys bring much to the table. Neither has any real life experience with that which you both pretend to know so much about. It's a little frustrating for those of us in the field actually "doing", listening to you's "speculating" from your desktop dyno or wherever else it is you get your hypothetical information you deliver here. When I, and some others, come on and say something is good or something works, it's because I/we can prove it. At the end of the day, what people say about their own cars and stadegies and the ET page pretty much speaks for itself.
Am I to assume this is aimed at me and Bill? I can't read your mind.
I think I know what has worked for me, and I can evaluate the results others have posted here and at the TopET Page, yours included. Based on all that, I still contend that there is little difference performance wise between AI and LE with respect to the heads. However, I am starting to see clear evidence that the AI cam is working better, delivering more of the good stuff, i.e. tq. HP is for bragging, Tq is for winning. It would appear that Pat (and others like yourself) will continue to win based on the results!
For the record, I believe that AI has a better approach to delivering a quality top end than Lloyd. They provide the complete package, heads, cam, springs, valves, retainers, guides, etc. Lloyd directs you (or so he did when I got my setup 5 years ago), and leaves too much to chance. I never, let me repeat, NEVER had a single valve train related issue with my LE2 setup. I bought good parts, and had them put together by a competent engine builder rather than assembling the parts myself. There is a lot to valve train setup that if not spec'd and built properly can lead to problems, and in my view it happens mostly with Lloyd's customers than to AI. Lloyd is a porter, and outsources much of what AI does in house. Therefore, they get better control over qulity, and that definitely counts for something.
