LS3 Conversion 1999 XK8
Just completed my LS3 new crate motor with new 6L80 automatic. Re did all suspension bushings , shocks HR springs new Michelin 255/40/19 285/35/19 . 2.5 over axle exhaust . Car drives and preforms like a brand new car. The help from Andrew ant Jaguar Specialty’s was fantastic. He worked with us thru any issues we had many times on weekends . Fantastic car way better than the car was new with old motor and set up.

I have 7 to & months just working on it when I could. The install went fast the new GM harness was wired backwards spent more time thinking I did something wrong before finally found that. Motor and Transmission were all new from GM. I think all in with suspension, tires rims I’m close to 30k. But it’s basically new car and fun to drive. I am going to change rear end to a 3:54 positive traction I’m looking for one now. Get a little more low end it’s a 3:06 now. Good luck with your project
