Anyone out there running this combo?? 454/350trans/205 t-case/4.10s/38 1/2 Swampers What type of fuel economy (or lack there of) could I expect? I I'm looking into a truck w/this setup, and crying every time I drive past my dad's gas station, who is charging $1.99/gallon for REGULAR UNLEADED (as in 87 octane). Will this do any better than a 350 ci with this combo? Dave Hiller 90 K-5 "The Anti-SUV"
