Have a 2005 tahoe z71 with a normal 5.3l..Want to go 400hp.And ideas that would be helpful

 

Long tubes and Y-pipe, cam, gen 4 truck intake, tune.

Won't be much of a sleeper with a cam though.

 

Add a converter to the list

 

 

I appreciate your opinion but on the track I have seen a Tahoe Suburban that's bigger than mines have twin turbos and pushing over 1000 horsepower and six hundred and something to the wheel so anything is possible besides everybody know 5.3 is basically an LS engine. I might not can beat a Hellcat or SS2 but I can guarantee you I can be the SS I can be the 5.0 Mustang if I had the right stuff but appreciate your opinion

 

thanks for advice if it was you what would you do I mean I know if I put a supercharger on there redid the heads and everything else then oh oh yeah I'm for sure I'll be probably making 500 HP just looking for advice from the ls guys preciate it fellas

 

400hp is a long ways from 1000hp...I think the better way to build a sleeper is to shoot for a quarter or eighth mile time so how fast do you want the truck to be? Also I've never drag raced so take that with a grain of salt.

 

 

first off I was letting u know anything is possible, second I wasn't comparing I was using it as a example that anything can be possible if you put work in it but dude if you going to be negative can go somewhere else with your negativity I'm not looking for that. I got a car and it's a 69 charger with a blueprint engine 535hp. I'm only interested and having a streetable muscle car now for my Tahoe that's what this subject it's not used to race I only want a little more horsepower out of it

 

Cold air intake, Edlebrock TSV 2300 Supercharger American Racing Long tube headers Corsa exhaust, Mike Norris tune-Go have fun and get better gas mileage!!

 

cool!!Thanks one question though. Wat u think it will make on the dyno..like give your best hp

 

If its making over 1000 HP and only 600 at the wheel, there is a major major issue there somewhere.

If you want a fast sleeper, hop over to On3 and get one of their single turbo setups with goodies for $2500. Leave the engine mostly stock.

 

My LS3 made 560 to the tire...

 

cool I'll try that appreciate it

 

would it cause problems with the 5.3 vortec oil pump if so wat other oil pumps other than factory could I use?...

 

You might believe anything is possible, but I would be very surprised to see a 400hp tahoe gap a 5.0 stang. All that being said, I think the others are on point here your engine would like some boost.

 

 

super nice dude well I thank everyone for the advice it is very helpful. I just want to have fun with something as my own creation. To be like yo I did this so it definitely would it be a big accomplishment thanks guys

 

Good luck man! You're right, there's a certain level of pride making something out of your own creation.
