Been watching this thread with a smile BW as you know I am a FSJ guy at heart. Was even tempted to jump into the diesel vs. gas discussion but controled myself. I have about every type of engine out there except a 4 cylinder and am slowly switching over to diesels for a completely different reason. Mine sit more than I would like and the gas goes bad. Smurf (my 79 Chief) is great example, TH400 sent bad and I was working on other project so it sat too long and gas is bad. It has duel tanks and will be a major PIA to address once the transmission is fixed. My M715 is a military 6.2 with NV4500 andI love it! My daughter drove a M1009 in high school and Dodge Ram 250 with 12 valve first two years of college. I LIKE the older, all mechanical diesels because they are non computer and easier to work on.
