Working on the engine is generally easier in Lil Red than it was in the GMC - the truck is lower, and there's more room in certain areas (rear of the driver's side head). Plus Lil Red has a lot fewer miles (about 10k), has never been apart before and has never seen road de-icer.
I was a little more cautious with the nitrous and propane in my 6.5L. You gotta keep Lil Red in top-notch shape, you have LOTS of sweat equity and brain-power equity invested in her.
