1995 Tahoe 4wd Engine mods, fuel and power effeciency

[CavTahow]

I have a 1995 Tahoe LT 4wd

Has a 350 5.7 engine, 3inch Body Lift, 33in Maxis Buckshot
Im thinking about installing a K&N Cold Air Intake from JC Whitney, a throttle body spacer, and MAYBE some headers (Dont know what brand)

Anyways, Is there anything I can do to improve fuel mileage and engine power??
Brands? Thanks guys!!

You are on the right track already. There are some other here that can give you details on TBI uprades. Just be patient.

shop on ebay for the CAI, actually get a Volant instead of the k&n system. way better. just sold one for a tbi, month to late

theres tons of information on this site, you just need to search it.

elec fans, exhaust, a solid tuneup, too much to list..

Free TBI mods ...

thats right Retorq, flipping the TBI hat over, taking the black thing out of the fender, all those are free, you just have to get out and do it yourself

I was talking about shaving off those air foil things on the top, raising the injector pod and shaving the throttle blade screws but yours work too.

there all free! lol

My Engine already has manual Dual Electric Fans, the Air intake isnt connected to the fender, Its simply the round drum cover that is flipped upside down to expose the air filter. lol

So that's already out of the way. QUESTION-Should I always RUN the electric Fans??
Or only when Im sitting in a drive through at Mickey D's???

Also Will a good brand of headers add to fuel milieage??
I heard something about Gear ratios. Mine has the stock 3.73 up front and rear. What can I do to the gear ratio?

manual dual fans??? you should get a thermostat for those instead of worrying about everything. Dont keep them on 100%...

gears are fine where there at..

if the intake isnt connected to the fender, then your sucking in hot air constantly. I have no idea what your talking about with the round "drum cover"....
****** pic, but you get the idea


headers and a free flowing exhaust will only help if you have a decent ait system as well. Brand on the header wont matter for MPG gains, but if you do longtubes or shorties that will matter...

Having your fans run all the time will actually hurt MPG ... they will cause turbulence at higher speeds.
