Engine upgrade

[Tahoe everything]

Good evening

I am new to this site , I would like to make my 2001 Tahoe faster .

Z71 package
5.3 engine
4L60E transmission
3.73 gears
Everything is stock

I Wana make extra HP anywhere between 75-180 HP to the rear wheels .


I have the capability and resources to get whatever needs to be done , done.

I don't want to break into the bottom end of the engine from my understanding that part is built pretty well already and can handle up to 500-600 HP ( correct me if I'm wrong)

I don't need a loud idle chop. Any suggestions are welcomed and appreciated . I'm here to learn and make my Tahoe faster thank you .

Basic upgrades that could probably get you about 20-25hp (just a guess) would be exhaust, CAI and a custom tune from black bear performance (or somewhere else). Don't get a throttle body spacer, in some cases it hurts power for some reason in these trucks I don't know much about it, someone else can explain why. Headers is another good one. The most you could get out of that is maybe 35hp (another guess). I don't know your budget but a good cam can put you into that range along with the other upgrades.

243 heads milled.0030 and a medium performance cam will get you almost 100 HP

What engine do you have? LM7 or L59?

My budget can go to 3 grand if need be . I just want to make sure I do everything right and research and get a bunch of information from different sources prior to starting this .

$3K will get you all the bolt-ons, cam, all the accompanying valvetrain upgrades (valve springs, pushrods, trunnion upgrade, etc) and tune. You may be able to squeeze some mild headwork (millling for compression, etc.) in that budget, too. The kicker is factoring in labor costs. My assumption is that you'll be farming out the work because if you were already set up and capable of doing the work yourself, then you'd already know what was necessary for getting more power out of this platform.

Gonna watch on this one. I'm really curious what guys will say.
