I want to pull a little bit more from my 5.3 and wanted to see what yall recommend..... I have a 2002 chevy silv ecsb z71 5.3 its bored .030 over 224/230 .610/.610 110lsa, adjustable timing gear advanced 3 degrees, ported and polished 799s milled to 58cc, pac racing springs 1.7 rockers, TBSS intake (egr deleted) CAI, long tubes with high flow cats and magnaflow muffs, FAST 92mm TB, black bear tune, 150 shot, 2500 stall, built 4l60e, have 4.10 gears not installed yet (3.73 current), currently running 315/75/r16 mickey thompson baja mtz.... im am wanting to stay natualy asperated so what do you think should be next for a little more power?

 

If you dont have the 4.10s installed i would send them back and get some 4.56s especially since you have a 35'' tall tire. You would get alot better off the line with 4.56s.

 

Well the 4.10s was given to me so i have nothing in them $ wise ... but i didnt want to rape my MPGs

 

From what i hear 4.56s will actually help out the truck bc of how much less you have to get into the throttle. But if they were giving to you then, you cant beat that.

 

im sure i can find someone to trade my 410 for 456 and a lil cash but this is my DD

 

Yeah very true im sure someone will want to trade im currently looking at either 4.56s or 4.30s for my dd these 3.73 suck!

 

Yea 4.10's will probably net worse gas mileage then 4.56's with 35's....in the city atleast

 

My next move will be smaller tires or more cubic inches.
