im going to put bigger tires on it so that will help a bit. is there a common rear end with better gears that i can swap in? should i mess with the timing. i dont care about hp or performance, just gas milage. andy help is appreciated. thanks

bigger tires weigh more and increase the final drive ratio, skinnier tires offer less resistance and can be beneficial, a low resistance intake filter and free flowing exhaust should increase milage and increase performance, of course the go pedal negates any gain

i understand that the wider the tire the more resistance to the road, but being 3-5" taller should help out. all my driving is highway, about 60 miles. my job is less than a mile from home and from work off the highway.

ive actully been driving 65 and the gas milage is great. 60 miles and the neddles only moves a little bit, but...im that d@ck in the first lane screwin the flow up. everybody is doing 90 at 5:30 in the mornin and if i do that i burn a 1/4 tank there and back! thats worse than my escalade! mpg wise.

im def. gonna try the tires cause my buddy hase a set of aluminum rims from a tundra with tall a$$ tires, it cant hurt to try. but is there something i can do gearing wise with the rear end. i wonder if i can put my spare Q rear end in there hmmm...but is there a known easy swap?

as far as free'er flowing intake, should i just buy one of the filters that look like a reg, ring filter but with the filter part on top too. like the k&n but not...and just leave the top of the air filter cover off. i dont think hot air will be a prob cause its cold *** balls!

what can i do cheaply to free up the exhaust other than cut it off. when i got it the muffler fell off will i was driving home. no power and way too load, and prob worse mpg.

all suggestions are taken into consideration, but keep in mind this a 500 truck and will be used till the body falls off, so nothing crazy. the cheaper the solution the better.

thanks

have you given it just a basic tuneup?

that's a fuel injected z24 isn't it?

yep everything mechanical tune up wise is done. dont get me wrong, it gets great gas milage... i just want more!!!

i want a low 5th gear or a better final drive. i want to be able to do 80 at 2-2500 rpms. im not willing to pull the tranny, but i will swap rear end rings or the rear all together.

does any body know the final drive ratio. ill just look for somthing higher, and by higher i mean lower and slap a diffent rear in there. i mocked my Q rear up, but id have to weld supports for it to sit on the leaf springs. rather not but its a possibility.

thanks
