500 whp is possible but you will need some serious heads with some compression along with a good size cam and matching intake. Look at Holdeners 600 fwhp recipes on youtube to get an idea of whats needed. At that power level your 4l60 will check out in short order unless its built to handle it.

LQ4 is the wrong core to start out with, if you want to avoid "rebuilding". Get a LQ9 instead.
That said, 500 HP at the wheels, is gonna take 625 - 650 at the crank. So let's go back a step: wht do you really want your truck to DO? Are you looking for some ET (HP doesn't give you that), autocross (HP is almost your enemy past a point), or WHAT? Where did that magic number come from? Are you going dyno racing with your buddies, or WHAT?

a fast 20-100mph and a fast 1/8,1/4 time and also still be able to use the truck on the street
What is your definition of "use ... on the street"? (long highway trips, daily commute, occasional fine-weather Sunday afternoons, ???)

fast in seconds, and occasionally use it in fine weather, not so much of a daily or long trips

either or to be honest, to make things easier i’ll be happy with whatever my lq4 can push HCI and full bolt ons, what’s the biggest cam paired with a lsxrt intake i can run on the 317 heads i don’t mind sending them for porting, or should i switch heads, i’ll be satisfied with over 400 to the wheels, wait till it blows then boost

They're immune. Must have taken a vaccine for that somehow. The following users liked this post:

So, my recommendation, put an On 3 turbo kit on it, make 600 some whp out of it easily. Beef up the trans and suspension and have fun with it.

1:Raised, didnt remove, TM from stock to 1,000lb/ft.
2: Recommended NOT installing a shift kit.
Did I mention a 3,200 stall Yank converter has been in there for 80,000 miles, too?
Tuner obviously knew what he was doing. But it would never live long in a 4,500lb-5,000lb truck....

I don't understand what is so hard to understand about the question. What do you want? A 10 second 1/4 mile truck? A mid to high 6 second 1/8 mile? Do you want it to go 120 in the 1/4? Do you want it to go 100-105 in the 1/8? Give us something, otherwise we all know the real answer, which is that you don't know what you want. Even after we get passed this interrogation, and down to what it will take motor wise to get there, you will be a stickler on what you want to do and more than likely just be an askhole and not take anyones advice.
