[PANAVIA]

Jody -- the SRX is a new version of their create a crate engine series sort-o-speak.

It is a recent development, and was released in may of this year. -- the new Roush engines are being constantly updated as they learn things and as technology progresses. You would think that building a 351W based engine would be rather a static affair some 10 years after Ford last offered them in a truck - not so , new parts are out all the time !
