I have been out of the game since 2012. My last big build was a widebody LS3 C6 with a TVS 2300 that Made just over 800 rwhp (A LOT back then). Obviously the LT and LS platforms are vastly different. I am going to start calling shops tomorrow and I want to make sure I can speak somewhat intelligently when talking about my build request.

From what I've been reading, If I do a Low side, Alky, Cam with flex fuel, It would be E30-E50, is that correct? Ive also had a shop tell me previously on this platform they won't do a cam without heads, first time in numerous LS builds I've ever heard of that?

The build below is what im looking to do (Car already has a GT Haus exhaust and MM Catch Can). Any suggestions to add (Not looking at heads)?

Stage 3 Cam
Big Gulp
103 TB
Kong X Port
LMR Lid
Pullies
Dual Alky
Low Side
ARH 2" long Tubes
Flex Fuel
Tune

There’s a bunch of good info on fueling in the Forced Induction forum. Definitely do some research there.

TLDR; get yourself a real fuel system. I wouldn’t screw with meth and you won’t need to if you can run E. Katech dual in tank pump and Too High PSI port injection is probably the best way to go at this point. Or if the 2nd ECU is more than you want to do, you can get a simpler (but more expensive) system using the BB HPFP and +50 injectors like I did. Run E50+ and rock & roll.

Well, with the list this big, just add heads.

[CamaroDreams76]

I have never heard of not doing a cam without heads. I didnt think heads were a prerequisite. Where did you plan on calling or getting the work done?

I took my car to Redline Motorsports in Pompano Beach but they closed and the owner now does LS/LT tuning and engine building for Vengeance Racing. Right now if you really didn't want to take a far trip I'd recommend K9 Motorworks in Fort Myers. Have a few friends with cars built by them and they run very well.

You definitely do not need to do heads on an LT4 to make good power. They flow decently well stock and with a blower, it’s just not going to be a massive power gain to do the heads.

Now if you’re shooting for big power, you gotta grab the extra power wherever you can.

(my) Family has the same ‘23 competition and its a beast. Compared to my 17 M6, no gears I could find to keep up w the “Competition”

You find the Z slower than the “competition “?

I should have added, I don't want to spend 5k on a fuel system I will definitely do some research in that forum. Thank you.

I will definitely check them out, they are very close. Florida High performance seems to have very good reviews as well. Thanks' for that lead, I will check them out.

That's exactly why I won't do heads. Not enough return for the money. Im not trying to squeeze out every last HP.

The ZL1 is absolutely slower 0-120. The Competitions are absolute Monster's when tuned, especially off the line with all wheel drive, Z wouldn't be able to catch up. I just raced a Plaid on the way home from a stop light, and spun all 4 tires for the First 75 ft due to it being only slightly damp. The S58 platform is really and engineering marvel, that's coming from someone who has owned 13 Corvettes, 3 Vipers and a Hellcat.

You don't want meth. It's a band-aid with a lot of downsides.

That's one thing I have never done on any of my previous builds. I thought it was as easy as keeping the reservoir filled, no? Looks like I have some research to do on that as well.

Depends on how you are using it. If you are using it as a fuel system then I agree.

If you are using it to cool the intake charge, get a little more octane, and run a few more degrees of timing then I think you are missing out. I can easily add a few degrees of timing and my IAT go down during a pull (TVS2300 blower).

I do feel that it gets a bad rap due to folk putting the system in the engine bay area. I've got mine vibe isolated out of the heat in my trunk and have been running it for years w/o a single issue. I'm using it for the second case above. If I turn it off my car doesn't blow up on a pull

One of the big misses people do is run Water/Meth on MAP sensor with a PD blower. Makes no sense based on PD boost curve profile. You'll place the system nearly at full duty cycle well below 4k RPM. This means you have to pull a lot of injector out of the primary fuel system. If the system fails you'll be missing tons of fuel! BOOM!

I run mine off of MAF frequency and therefore it has a direct correlation to airflow coming into the engine. My system only sprays a little to start with and ramps up to full duty cycle only at 10-11kHz (aka my max airflow). This way I only pull as much injector as required vs. a lot of injector at the start (typical when running off MAP). Also, when you are in 5th or 6th on the highway, accelerate, and don't shift you will build a bit boost but really don't need the spray. My system won't bother spraying until the airflow demands it.

Install is here: https://www.camaro6.com/forums/showthread.php?t=591564 . Only difference is I'm running two of the AEM V3 nozzles now. Note, settings on knobs don't look like what is in the pictures, they are probably closer to 45% and 80%. That correlates to 6kHz turn on and ramps up to 11kHz.

When I did my build we talked about porting the heads and the cost of $2300 for maybe an extra 20 HP just wasn't justified, so I agree. Also if the OP is talking a stg III cam he should also be thinking of a new stall converter if he has an auto. He won't be able to handle the bucking. Also he may want to think about GESI cats and 3" long pipes for the exhaust to improve flow. Don't see any mention of TCM tuning either which I highly suggest.
