Well, the old 6.2 was not going to cut it in my new k30 flatbed.. I've been quite impressed with the power out of the 6.0L in my k5 throughout the power band. It flat out gets with the program, and doesnt stop screaming until it hits the rev limiter at 6200. Heres whats going to motivate my flatbed: Another 2004 6.0L this ones got 27,000 miles.. I'm reworking the harness myself and i'm keeping the drive by wire setup instead of converting it to a throttle cable like my k5.. (since we figured it out on my buddy's 8.1L swap) I had the whole setup for sale for $2500, but it found its way into the engine compartment of my tow rig. Who's next for a 6.0L swap?
