Yes I did just do the swap with the help of Joe at all z east. The service was outstanding and i will be happy to help anyone with questions myself. The 390 is nice and i am very happy with the results of my conversion (I had a trashed r180 that would whine till you got a headace). I needed a few extra parts and joe sent them right out to me, no questions asked. All Z east is the first and only Z wrecking yard that i will ever call. Even if you have questions regarding installation they are knowledgeable and very helpful.
