500hp 6.0?

I planning on swapping a LQ4 into my 97 Stepside Z-71 when I get my tax return next year and I'm trying to educate myself in the mean time. I want to put around 500hp the the ground but I need it to be streetable at the same time. I know that it is very possible I just am not sure what would be the best(cheapest) way to go about it. I would really like some input from some of the guys that are making that kind of power to see whats working best for you.

im guessing without power adders cus a 200 shot will get you there quick :lol: but id say cam, full bolt ons, heads and intake, will get ya close :thumb: but then again just put a power adder on it.

you talking NA for FI ?

the cheapest route hook up a nitrous system and that'll barely get you there, if not then the word cheapest wont mean what it stands for when trying to attemp 500 to the wheels NA on a 6.0 ;)

my calculated track times puts me at 500+ and barely

I fully understand that it won't be cheap in anyway. I guess I'm asking for the best combo of parts without just slappin the most expensive heads/cam/intake and so on together.

without spending huge $$$'s on heads i would have to say the ls3 heads ported would be your best route. and a FAST 102 intake and 102 BIG MOUTH tb would help in a huge way, you can conserve on the heads since the ls3's flow numbers are sweet.. then surround that with a nice custom cam, it'll take the whole drivetrain to complete the whole setup though..

i have seen the l76 intake being ported flow some great numbers also ;)

i spent the dollars around my heads which are the ls3's with leight weight valves ;) to make my setup work..i've got every bolt on imagineable and some :)

I've seen a lot of people talking about 317 heads. Are they any good?

I'll start looking for a good deal on some LS3 heads.

get ready to spend just as much on the drivetrain to hold all of the power.

they are good if your going FI it wil lower your compression and you can add more boost:burnrub: if your gonna be NA i wouldnt use the 317 heads, your gonna want more compression.

317 heads are stock 6.0 heads, nothing special...

You can still make 500RWHP NA with a 6.0 and worked 243/799 heads. My old setup ran a best of 12.19 at 113mph and weighed in at 4600lbs. The calculators put me around 505rwhp. It consisted of LS2/LQ9 block, 243/799 ported and polished heads, 232/242 cam, TBSS intake, 42lb injectors, 90mm edelbrock TB, PRC dual springs and hardened pushrods, Heads were decked to 61cc chambers and bumped the compression to 11.2:1. This was also through a 4l80E with a 3200 PI convertor and 4.10s. Not really ideal for the track. This was also during the heat of the summer 100* plus. So I'm sure with some cooler air it would have been in the high 11's on motor.

turbo, big azz turbo

DBRODS is definitely right, theres some good lookin LS1s over on tech with some nasty stickies on how to make 500+ NA. An LS1 of course but still

yeah "but still" is exactly right, they have .3 less liters to work with, every little thing matters when your trying to get that extra 5-10hp out of it. you would be better off with a lq9 (just because its that much more compression) iirc Patric G got 500+ on some ported 241 heads (stock ls1 heads not ls6's)

yeah but still luke..

what you talkin about ducky

oh wait your agreeing with me. LAWLZ my bad i read it wrong

i was like wtf?!

This is why I'm trying to do some learning now, before I start buying things. Theres just so many different options and I don't want to spend more than I have to, but I want some serious power and I want it to be reliable. I drive this truck all most everyday and I off-road it everynow and then. I checked ebay last night and the only set of LS3 heads I found were right at $1300.00. Is that a good price?

Sorry for the off topic question, but are stock LQ4 heads best if you plan on eventually going FI?

many people go with them since they offer the largest combustion chamber of factory heads

Awesome! Then I'll scratch heads off the list & use the stockers. I thought these old iron heads were junk. My engine has over 186k on it & its going to get a rebuild soon.

317s is what most people run with FI thats the aluminum 6.0 head

200 more and you can some ported and polished ;) are those fully assembled ?

Yeah that was a fully assembled set.

get aluminum heads, you can run more compression before you get detonation with aluminum
