| Just traded my LLY for a LBZ - what should I expect?
Besides the obvious 6 speed tranny, 4.10's VS. 3.73's.
I know the LBZ makes I think 50 more HP and around 130 more ft lbs (may be off a little).
What should I expect for fuel mileage difference? I was VERY pleased with how my LLY ran & the mileage I got (consistant 18.5+ hand calculated).
Friend of mine has a LBZ & his turbo SCREAMS with just an exhaust & air intake - is that what they all sound like or does he have the turbo resonator off? LBZ sounds alot quieter as well.
Tomorrow should be the day, i'll post some pics up.

| the LLY in stock form does just a tad nit better on fuel economy then the LBZ but with a programmer and exhaust you can quickly take care of that problem..my LBZ screams with a straight exhaust and the CAI mod.

| Congrats on the New ride but i beleive evey dmax ever built has been with 3.73's! The trans gears are the same as well except the 6 speed has 2 over drive gears, 5th gear in both is .76:1 and the 6 speed has another at .62:1...... IIRC!
