Well, I didn't look at your post as being "critical", just not up-to-date. Especially since you were a full second off on performance.

While the Drag Packs do have some impressive specs, those engine and weight specs have to be adhered to as a legal Stock classed car. But they haven't reached their full potential under those rules yet. These combos are only a couple of year old.

Pump gas small blocks can run high 10's, but they have no rules limiting how they do it: Strokers, any heads, any cam, etc. There are 340 and 360 Stockers that have run deep in the 10's also. But there is a big difference and a lot more work and money in getting a car to pick up a half a second starting at 10 flat than it is starting at 11 flat.
Basically, as you get faster, each subsequent .10 is more work and expense than the previous.
