I almost had a donor ls1 6 speed for mine, but my wife decided to like it. Summer is right around the corner and surely many nice Z's and unfortunate T/A's will be driven beyond their pilots capabilities. Start watching C/L they show up from time to time. LS1 6 speed 400 plus HP turn key. At least 20 mpg drivin it like you stole it! Toss a good tune at it, and no cats! Dang stock up on rear tires, and enjoy!
