the LT4, stock, will over-power all street tires.
my wheels spin in 4th gear (manual C7Z).

Good to know, thought just the cam was needed to run more ethanol.

I think of it as increasing air flow

This is some of the things I’m thinkin about (some of em Im sold on). I really want mods that will produce the most hp gains, but I dont wanna do anything too crazy, mainly bolt on type of mods. (Willing to tune, thats cool since I kno its mandatory for some mods. Please provide insight & good advice. I want a good build that LOOKS relatively stock, but I want increase of 75-150hp & relatively same for tq. I also seen people mention ported blowers & ported throttle body??? Can somebody tell me the main benefits of those mods, and also if spark plugs are good performance/power mods?? Anyway here’s the list of current mods on my radar. Also want good power increase while maintaining traction on normal sport michellins or pirellis. (NO SLICKS LOL). Dont really wanna use ethanol either, 93 is available near me

Rotofab intake
(Maybe) Kooks long tube headers (sound is cool, but prefer power, dont want drone, or cammed type of sound. Or should I do full system?)
Pulley?? (I think lower pulley from what I’ve seen… again not sure. I seen cleetusmcfarland’s video of serious gains from just a pulley).

Im a newbie in car mods, so some of the stuff I dont understand Lol so can you guys "dumb it down" a little bit. I kno basics, but some things I dont know at all, or know the benefit (benefit contributes to whether I'd be interested or not).

Other than those I’m not sure what else to do, or if there is much else for what Im looking for. All advice welcom, thank u camaro fam��

PLAN A: 100 whp 93 octane

ATI 918856(w) Damper $450
ATI 916227 or Lingenfelter L220170709 150.00
GATES Greenback k080845HD $28.00 (amazon)
Rotofab $450
1 7/8 Texas Speed Headers or CSP $800
LS1 ATI 951499 damper bolt summit 9.75
NGK 6510 1 step cooler plugs 7.00 ($56.00)
Tune $500.00 to $750




Plan B: 125+ whp 93 octane

$1200 Kong or joker blower porting
$230 Griptec 2.3 puley
$600 to 650 103mm TB
Gates green back belt
1 7/8 headers $800
Rotofab $450
NGK Plugs 6510 $56
Tune $750

If you plan on keeping the stock blower I recommend Plan B otherwise I would not mess with changing blower pulleys it would waste money on labor and parts if you upgraded to a new blower later on.

PLAN A & B 150 plus whp

If you want to go all out keeping the stock blower do both A plus B. Cooling will be needed a 3 gallon bumper reservoir and the FI chiller would add around $700 for tank and $1400 for the chiller system plus the install. At this point you could keep it simple and do a 2650 and headers and be at the same HP level the 150 plus whp on 93 octane

Personally I would not pulley the stock blower nor would I bother with porting it. If you want more in the way of boost then I recommend going straight to the 2650. That way you will have much more potential in the future when you decide to mod even more (cam, ported heads, etc).

exactly this! I personally know too many guys who did the whole porting, pulleys, interchillers etc. Just to eventually either regret it or change blowers / go procharger in the end

That's a great package but terrible price. I was able to do all that for just over 2k I didn't port the blower because I knew i was upgrading to a 2650.

$800 CSP 2” Longtube Headers
CSP Ultra Catted Connection Pipes
$56 NGK Spark Plugs
$1200 Kong Performance CNC Ported Supercharger
$230 Griptec Supercharger Pulley
$650 Nick Williams 103mm Throttle Body
$450 Roto Fab Big Gulp Cold Air Intake
$300 Mighty Mouse Wild Catch Can System
Professional Installation

that's like 4000 bucks to pull the blower and install headers... maybe some

I hear ya, and if Kong doesn't work, I'll move up, but I believe that the 40-60F inlet air temps that I'll have over the next 7 or 8 months combined with 100 octane will neutralize any additional SC heat. We'll see.
