I have given my truck a project designation XJ-PU V12, XJ because all the running gear is from a 1986 Jaguar XJS as well as the suspension, PU pickup and V12 for that fantastic Jaguar racing designed engine.
What a lot of people do not know is Jaguar had a deal with GM and used a lot of there parts in the Jaguar models, my V12 is married to a Turbo 400 trans for example which to me is kinda bringing things back home in my mind, wish me luck
