So how are the X-type and S-type engines different? And what are the appropriate model years for the S-type? There are plenty of S-type motors available from recyclers, but the X-types are still too new to find. Any drawbacks with the Jag engines vs. Taurus vs. LS in terms of engine management electronics, e.g. does the VCT require extra signal paths not currently in the harness?

Terry, if you're willing to divulge, will the non-Duratec you're doing in 2002 be based on the LS or on one of the Jag engines?
