Re: Projext "V8 XJ" Build

I wouldn't consider the 4.8 as an option, it's a lot of work for a small gain. The 5.3 is a good economical option, but depending on how you use the car it could leave you wanting more. If you can swing it go for a 6.0, in hindsight I wish I had saved a little longer for a 6.0.

The wiring isn't that difficult for either the XJ side or the GM harness and integrating the two. Check out for all of the GM information you could want/need.

Good luck with with the build.
