you are correct. I can't argue with anything you said. But, I'm just not going to load up a engine, drive 1 hr, spend the day and $$$$, then return home. Usually I end up impressed at what the ET is, and perhaps I'm still leaving something on the table. For example, my 318 did exactly to the "T" on the ET, and 1 mph faster on the mph than what I intended it to do. My 360 has exceeded my expectations. Now this build??? who knows, because who knows what parts I'll find, what car I'll find.
