I have an 04 Z16 and am seriously considering an engine upgrade. I am looking at: 1) the Callaway NA 6.8L advertised at 550 hp and based on a GM Motorsports C5R block ($26,300); and 2) the Lingenfelter NA 7L advertised at 530+ hp and based on a "custom" aluminum block($19,995).
I would like some knowledgeable feedback on the respective merits of the two engines and shops. Price at this level is not quite as important to me as quality (that is, unless there was not a qualitative difference between the two--then price would be the key issue).
Thanks for your help!

ps I am located in the middle of Missouri, obviously closer to Lingenfelter than Callaway, but still quite a distance from Decatur, Indiana.
