Any ideas how to rebuild my 6.0 to get better mileage?

 

Sell the 6.0 and put in a 4.8 with a supercharger.

 

Small cam (w/ high manifold vac) more compression?

 

build it into a 4.3

 

Also set cruise to 70 and re-gear for 1900-2000 rpm.

Do all the usual suspect bolt-ons they help. Get atleast a roll up tonneau cover, and put on the factory 17's with atleast a 425 treadware. I tried stock Caddy 18's and went from 21-22 to 15-16 so tire selection can be the biggest hurdle.

You can try roller rockers they will reduce friction, but I never used them for mpg.

I just got some BFG 275/60/17 tires with a 580 treadware, and they do handle better. I haven't done a mpg thing yet but it shouldn't change. That and they look as cool as the stock painted poverty caps can look.

 

they would come from the factory with rollers if it helped mileage.

 

coustom tune - not a hand held
drop in K&N filter
free flowing muffler - anything besides a Flowmaster or one with baffles
tire pressure
change your driving habbits

 

No they wouldn't. GM like Ford, Dodge, Toyoda have to build comprimise vehicles so we can afford them. If you throw every little thing at a truck for instance to get more power, mileage, reliabilty they could price them out of many peoples hands.

Look at how Ferrari builds cars no comprimises. All they need is whale ***** leather to catch up to Russian tastes. Ferraris also start at $192,000 dollars so take my $22,000 dollar truck minus it from the base Ferrari costs and I have roughly $170,000 to make improvements. Now we all can imagine what can happen with that kind of money to spend on motor, suspension, transmission, and interior. Plus we easily would still be able to hire a good series of lawyers to get us off for out running the cops.

Also every car company knows theres people like us who are never happy with what the factory offers, and are willing to go further. I can tell you if my wife gave me the credit card and damn the project house I would be rocking a 6-8 drop, and 500 RWHP day 1, and maybe get the seats reupolstered in a more classic style.

That or otherwise you have a lawn mower handle on your honda rocking the downforce it creates.
