These are cool screen shots. I went back to see if indeed the marking is limited to 85 but I did not find that. I got pictures of pre-85 engines that show the "lamborghini" marking as well. Some 84 do have the 85 bumpers too. I found the markings on but may not be limited to: ELA12759 ELA12711 (I saw that car in the flesh from Steve Waldie) ELA12672 DLA12596 The fuel injected parts are clearly in the manual. Could it be that the factory had them made and they were shipped with the cars pre-85 ?
