I personally would not use Ultimate Z. I've heard horror stories and just refuse to have anything major done there. I personally know the new co-owner of Sound Performance (Chris). I can guarantee that he will stand by his work. He is a very standup guy and I've known him for years. I still would probably get an engine from Kyle but then have Sound Performance install it. But if you really want a local build, call Chris at Sound Performance and let him know that Tim sent you. He knows my Z very well. ;-)
