i apologize i'm sure this has been talked about a lot on here but i'm looking to get some more power out of my daily driver 04 z71 sierra.

it has a spectre cold air intake, a cat back and a custom shift kit with a corvette servo. pulling a camper or a boat it still feels WEAK compared to a titan.

its a daily driver and i have a 2 month old so a 6.0l swap, turbo, supercharger are not an option. dont really want to mess with the gears yet either. when its retired from daily driver duties i will but till then.....

i have read about the 6L cam swaps as well as the ZO6 cam and valve springs. are these going to do anything noticeable for me or not? i dont want to run it on 93 octane either.

plan on a custom tune but wanted some info on a good cam and possible valve spring combo


thanks

 

Seeing as how your options are extremely limited, I'd start with a tune, no question.

 

Do 4.56 gears if you don't want to swap engines or FI.

 

so no gears, and no 93 octane tune, definately get a nice cam and a good tune, but a 87 octane tune wont get you as much power as a 93 octane tune, any reason on why you dont want to change the gears?

 

I haven't gone into FI, but everything except increasing cubes is bullsh*t for increasing low end and towing power.

Probably the mod which will give you the best increase in towing power is a NNBS intake manifold.

 

the truck is a daily driver and sees a lot of highway time when pulling the boat or camper to the lake, diff fishing holes and hunting. i planned on gears down the road when its paid off and no longer a daily driver cause it will have 35's under it then.

the same thing goes for the 93 octane tune. i just cant see dropping another $8-10 a tank every 10 days or so.

 

what about the truck line of cams that comp cams has? i was thinking about one of those cams and some upgraded rockers.

i'd have to go with an 89 octane tune for sure then, correct??? that would be do-able but i just cant see running 93 in a 4x4 daily driver.


all this talk really makes me want a 2wd with a built 6L and a t56!
why did chevy not built this truck?

 

do you have a link or anything with this intake? i tried googling it and all it brings up are other forums talking about it

thanks

 

Get a supercharger. KB is selling his rousch for $3500 I think.

 

my wife would kill me for sure! heck if i were gonna spend that much i'd just sell mine and get a dirtymax. torque for days and fuel mileage. more and more i think about it the more i kick myself for not going that route to begin with


NICE truck by the way! very clean without all the factory badging on it. those yr models def need that lift to look rite
