Just wondering what would be a more reliable set up? I have put heads and cam set up's on my 97 ss and 02 ws6 and was allways having to mess with something to keep everything running ok. I have never messed with any FI just wondering how reliable this set up is, or what im am getting into.If FI, what is the best system out? 09 vet m6, LG tong tubes, high flow cats, corsa extreme, K&N intake, RPM tune, and yes i know the C,E light is on in the video that has been fixed now. Thanks for anyones info.

A good H/C/I will get you over 500rwhp for sure but believe me you'll love FI.

Get yourself D1SC from Brute Speed or Vortech from A&A with 8-9lbs you'll be close or over 600rwhp with great drivability too..

LS3 are very strong engines you just need the right tuner.

Prices wise since you already have the boltons I think the H/C/I will cost a little less than FI.

How much power do you want to make? Porting your stock heads and cam change will be way less $$ than FI - kind of depends how fast you want to go and how many $$ you are willing to part with.

Well not really worried about money, I mean i dont want a $12,000 turbo set up. Im lookig for 1. reliable 2. power 3. cost. I have allways been a N/A guy bc thats all i have ever raced. Just wanted to know if $3,000 more for a SC is worth it? Im looking for 550-600 rwhp, Is that to much hp for the bottom end of a stock ls3? Thanks for the help

for SC it will cost a lot more than $3000 maybe double the price.

The LS3 are known to handle 600rwhp easily.

I know a buddy of mine with a C5 ZO6 ran around for a while cam only factory longblock, with a vortech s/c at 8psi, made roughly 600whp. the boost bug got him and he built a forged 347 lol, hes now got the compressor overdriven and maxed out at 14psi makin 700whp lol hes lookin for a YSI

Another vote for boost here...

The vette in my signature has a mild blower cam. The extra power comes in just over idle and only gets better from there on up. It's like having a built big block with a bad attitude under the hood. Yet still gets 25mpg. 672 at the wheels on 8.5 psi. I've had it on for almost a year and wouldn't change a thing. TVS on the street is a whole lot of fun. Boost is instant at any rpm.

Seems like a lot of gear for that much power on the street.

You're right on. Added the 4.10's when it was cam only. Way too much now. Just found metal in rear diff fluid. RPM set me up with a stock Z06 rear. It will be 3.42 as soon as it's installed. I think that's right where it should be given the way the power is delivered.

Sounds about right. You'll enjoy actually being able to use your gears, instead of:
blam spiiiin, blaam spiiin, blaaam spiin, blaaaam spin...150mph

That's about right. Last time at the track, I couldn't go full throttle 'till 4th gear

That sounds about what I want, I dont want a hight lift cam just something with a low lsa maybe 112 or 113 just to make it sound nasty @ idle, and a little more duration @ .50. I know that sounds dumb but im not a big drag racer or HP #s guy so idc if I leave some hp on the on the table.

You are going to leave hp on the table with the cam you describe. You're adding a blower....you already have a sweet set of heads and a good exhaust. Don't put a cork in things by running a low lift cam. The LSA on my cam is 115. Even at a 900 rpm idle, there's no mistaking it for a stock cam. Near perfect manners too. I could slow the idle down to 650 and get an even meaner sound if that was desirous to me. You can have your cake and eat it too if you put the right combo together. Patrick G did my cam and I'm totally pleased with it. Getting him to do one for you would be the best $25 you'll ever spend.

With the right cam, you can make some serious power at mild boost. With the wrong cam, you can make good power too. It just takes more boost to do it. More boost = more heat and belt slip once you get over about 9psi.

He spec'd out my cam for my Procharged LS3 too.

Yea my reason behind the low lift cam was keeping the stock valve springs, and i have been hearing stories about poping the head off the valves with a high lift cam. I gues it will be prety easy to change the valve springs on a vett since the engine dont sit way back under the fire wall like camaro or trans am. What do yall think, comp 918's with a good set of titanium retainers, 560 to 590 lift 230 something @.50 113-114 lsa? does this sound about right? Im going to get a custom grind like you said, im just trying to get an idea what a good blower cam has, and what a FI engine needs, cause im a N/A round track guy.

best thing to do is pay Pat G his 25 bucks for him to custom spec you a cam, or LME or Virginia Speed. they have more than enough real world experience to give a great cam, then have comp or isky or somebody grind it for you. EPP had a great blower cam, find Bod@Brutespeed on here, hell prob remember the specs, EPP went through some changes so i dunno if they are still in business.
