5.3 - 700hp build options? First ls motor, ive seen alot on these and want to learn more, so for my first build i could use some direction. I have a 2003 yukon 5.3 lm7, looking for a few options on how to make around 700hp and be dependable and streatable. Just got the block cleaned in a hot bath and we're ready for install process soon as I get the parts I will be using.
Going into an 86 z28 Camaro.
Trying to avoid turbo or supercharger, considered a forged bottom end for safety, don't want to put all this money into it just to blow it up. Have considered a used p1sc pro charger. Anyone have some build sheets or ideas to go off of. And if I use the stock heads (which I'd like to) what kind of work would they need? Ideas on cams to run procharged or not. Intakes for either option? Give me some ideas, I realize 700 hp non turboed would be pretty hard to achieve, would love to get there NA but...
Oh and I want the cam to sound mean and Lopey but don't want to go too nuts.
And no, I'm Not punching it out to a 5.7 nor am I making it a stroker or changing the crank specs other then maybe swapping over to full forged bottom end. And no im not getting a 6.0.... Money is tight at the moment. I'm working with what I have and trying to put a serious build sheet together.
Thanks guys!

700 horsepower from 325 cubic inches AND money is tight right now would be like saying "I just want a free hooker"........
What the most cost effective thing to do is forged Pistons like Wiseco junk yard dog ****; trail blazer SS intake and a Borg Warner S480 turbo
With a small 224 @ .050"/.566" lift cam and psi 1511 max life valve springs you can make easily 600 flywheel on 8-9 pounds of boost and 750 or so on E85 with 14 pounds and total streetability

Well that's why I'm kinda thinking of doing a turbo but Ivery never messed with them ever so idk how to set it up for one. And I really don't want to blow it up. Guess I could ask if it would be better to just buy a procharger or get an actual turbo

Go with a turbo. Do some research too. Check out "Sloppy Mechanics".

No that's not my main reasoning behind picking what cam I do. I just stated I liked Lopey cams. Thanks for your "support". If you dont have anything to say to support a new guy just getting into it then move along and say nothing, don't be a dick
Camming a turbo is way different than NA. Characteristic cam lope is actually a vacuum leak at the valves. With no vacuum, you have to cam differently.
You should probably talk with Martin Smallwood about the cam selection

I know you have to go by duration on turbos, I just haven't messed with them and it seems like a big hassle to build a turbo motor. I've been trying to decide between turbo, procharger, or supercharger for months. But superchargers are way out of my budget. And turbos seem to get expensive on e you add in waste gates and intercoolers and plumbing and such. And this motor is being built to be like a prostreet application. Go get groceries and then go to the drag strip Kinda idea.

700 HP on a 5.3 N/A is going to cost 3-4 times as much as 700 HP with a turbo and be FAR less streetable.
You will need to replace almost EVERYTHING with the exception of the crankshaft for 700 HP on a stock cube 5.3. I'm talking pistons, rods, rings, bearings, heads, rockers, pushrods, springs, camshaft, lifters, full exhaust, intake, throttle body, and pretty much every other piece of hardware that isn't either the crankshaft or block itself.
Want to know what you have to replace for a 700 HP turbo setup?
Fuel injectors.

Tell you what. the cam i have for my single 88 i think will chop. im doing an sbe L33 5.3 with a single 88, ls7 lifters (just found tout those come in it from the factory), Gapping rings top .026-.028, secondary .034 per A.R. from above input, struab trunion upgrade, pac ks016 spring kit, vic jr, blow through, daytona sensor ingnition, and race gas if it needs it for detonation. Itll make plenty. its not breaking the bank, and its going to sounds good. Best of all worlds
