Anyone swap a 98 or newer 5.3 into a k5? I saw the article in 4 wheeloffroad on the 6.0 conversion but I don't want to spend $5,000. I know where I can get 2004 5.3 with under 10k miles for around a grand. I figure the extra 100 horsepower, increased mileage and (hopefully) reliability would make it worth the headache. Any ideas?
