wlowe said:The '98 12 valve is considered a rarity because it is the only year that the second gen trucks had a 12 valve engine. The '01 is also a semi-rarity because it is the only year with both a rear disc brake Dana and front axle disconnect. The downside is availability of parts since the rear disc Dana was only used for two years. My vote is for the '01.
Last time I checked there were exactly 12 valves in my 2nd gen 96
