...of sitting in the driveway, the K5 is rolling on it's own power again. The new 396 has been sitting in the K5 since last October, but I havent spent too much time putting it all back together until a month ago. Before putting the big block in I rebuilt my TH350 because reverse wasnt engaging. I took it out for the first test drive on Monday and it was definitely a sweet feeling to be driving it again. The tranny rebuild did the trick because now it performs flawlessly. Of course I've only taken it down the street. Open headers are L O U D! It's getting the Flowmaster 70's put on it tomorrow though. I cant wait to take it out for a real test drive!
