Great!!
Use the Axiom block and heads, the VX wiring harness and intake and injectors and you'll be Golden. Everything else is the same... even maintenance later... Oh, and if you buy the Axiom engine and it has the intake on it... you can take the FPR and the EGR off and use them on the VX intake... they fit and would be newer than what you have on the VX.
If you have any other questions, don't hesitate to ask.
Good Luck!!
