Building another 6.2L powered vehicle
My 99 Suburban, 4.10 gears, 115K with marine injectors.
Was getting 15 mpg with 245/75R16's.
Now getting 18 mpg with 285/75R16's. They just barely fit, but it sits nice and the BFG A/T rubber looks mean.
Both fuel mileage indications taken from my regular commute. 13 miles one way, till I hit 1/4 tank. 42 gallon tank. 55 mph speed limit, with the cruise set to 57-58 per GPS since the speedo is now off. 2K RPMS for 55 sucked with the little tires.
05 2500HD CC LB LLY, 4x4, 3.73s 235/85R16's, webasto cab heater, to keep it warm.
03 Buick Rendezvous - When you average over 80 miles per day driving around, you need one of these.
85 K-5, 6.2, SM465, Rockwell T221, 1 tons, 36's. More goodies to be installed as time and money allows.
82 K20, 6.2, SM465, NP208, stock except for bed rack, snow plow, and glow plugs are on a toggle switch. It works great for plowing!
