I have the SR and am very happy with it. It is a beast and probably more than I need but nothing better than having an actual 427 in these if you ask me.
I saw all the negative posts in that thread. Not sure if those folks have ever owned a Roush or are just wishing they could. Mine has ~2300 miles and runs great so far. No
oil burning or other issues.
Find a local Roush mechanic and ask their opinion.
