Ok.... Heres the deal... I have a 79 xj-s V-12 with a rebuilt engine, less then 10K miles on it... runs and drives great... electrics are very flaky, as well as some other things...
I also have a 89 that all except the engine are exceptional, including a brand new trans.
Swap the 79 engine into the 89? (89 has marrelli ignition) Any problems anyone can foresee? I do have to do emmisions testing here.....
any thoughts?
Thanks Patrick
