I am new here, and don't even have a Z yet, but am looking at one this weekend, and want to put a Chevy LT1, or LS1 V8 in her. Are there any pro's or cons with going with one from a Vette rather than say, a Camaro, or Impalla? Also how tough are the rear ends on the 260Z's. That is what I am looking at this weekend. Any help, or suggestions are greatly appreciated.
