this is not really on a TITAN it self, i have a friend who has some pull with a dealership, and we have been kicking the idea of stuffing an endurance motor into a first gen Z car. i know there are some NISSAN techs here. my question is, what are the dimission of the Endurance V8 over a 4.5 from a Q45. some has done this swap and it was tight fight. but i believe a 5.6 does not have as wide as valve covers as a 4.5 does.
here is the like to the swap.
