I don't own one, but I know a little about them. If your going to have engine groups then you should put 4.6/5.4, 5.0/5.7, and probably other for the really old crown vics. Even though they never came with a 5.4 theres some who've put one in place of the 4.6's. What type of info are you looking for, or is this an attempt to gain support?
