As noted above, if you have enough money, anything is possible. The engine controls on the Jags are different, so you'll have to find someone who can interface the Jag engine controls with the LS's computers, or adjust the LS's PCM to deal with the Jag engine. Either way, it ain't gonna be cheap.You should put a Jaguar Motor! Type R!!! Is that even possible?!?!? That would be SIiiiIIIiiIiCK!!!! Lincoln LS R! W/the jag logos on grille, back and sides! Fast too!....Like I said though..... Will it fit?!?!?
