Well I would comment that this cam is basically a copy of the stock cam.

The question is, is that what you want or do you want to "improve" on the stock compromises?
Mr.Pence tried to answer that question and judging by the users reviews, is an overwhelming success?
If you are asking what is "in stock/on the shelf", that is a different question. The answer is not a lot. Virtually everything that I look at now needs to be ordered and that generally means that they are not stocked/ on the shelf by the manufactures and need to be made for you?
That by experience means some sort of waiting time.
Rene ordered a custom cam and got it pretty fast considering it had to be made for him.
It has a little more aggressive timing then George P's cam but they are very similar.
Both are hydraulic roller lifter designs so there is additional expense involved as a result.
The other thing to consider is that you are asking others to judge for you what a good solution is. As good as those intentions are, you may not agree after you install the thing, run it and judge it to be a lousy choice.
