Hello all. I'm a diesel tech by trade for over 12 years. I have built countless engines and I have all the tools and knowledge to get it done. What I don't have is experience building LS engines. That being said I have a question.

I hear car guys always talking about the different parts off of different generation engines to produce power. I have a 5.3 iron block I want to build and I'm looking for something to read to get a better understanding on what is compatible to my engine.

I have 2 sets of different heads, gen2 connecting rods, and 2 complete kits including ECM and harness to get it running.

Looking for suggestions on a cam kit for my WS6. Also any other mods to go along with a cam.

ive been thinking about a c5 vette but how would a 4th gen firebird or 4th gen camaro compare? as they all have the same engine but those are 2+2 (and cheaper)

I've got 16k budget so i think i could find a WS6 for the firebird
I really like theses cars as i want either a targa top or t top

Being built at a local performance shop

Having idle problems and assuming this is the reason. Anyone know what hose this is and the PN?

Have a lq4 and wondering what yall gap yall sparkplug and when going up hill knock retard is 5 degrees at 4000 rpm and at idle and driving it has a strong fuel smell currently running 0.04 i put new sensors and stuff on it

Any objections to upgrading the 4.8 ?

I have a nice truck I just bought with a blown 4.8 any objections to keeping a 4.8 Which I have an extra motor for I'll post pictures when i have it in my drive way. I rebuilt my 2008 jeep srt 8. Everybody's telling me to drop in a ls3 but I believe I can drop in my 4.8 that has new heads and intake. It's going to be my work truck with a little kick I think with boost can be a solid truck.

Looking for a reputable shop in or near MS to do a lifter swap & possible cam replacement. Willing to drive a few hours if needed. Who y’all got?

Hey everyone! Just looking for some general input on how to squeeze some more power out of my 02 Camaro SS. It has long tube headers, a 93 octane tune, LS6 intake, SLP intake, rebuilt tranny with shift kit (A4). I’d like to get a cam but I can just barely afford the cam with new gaskets and etc and I know I’d need to tune it. I’m in southeast florida and the best price I got for a tune was 1500 dollars 🫣. I was thinking about porting my throttle body but I hear it doesn’t yield much power. I’d ideally like to make 420 to the rear wheels. At the moment it makes something like 375 to the wheels. It also has to be daily driver friendly as it’s my only mode of transportation. If the advice is leave it alone til I get some more money I understand but I was curious. I felt like the price of street tuning a cam being 1500 feels kind of ridiculous and I called a few stores and that’s the price I was given. I was also looking at heads but it seems pointless if it’s not paired with a cam or at least some sort of forced induction which I’m not opposed to but am just not familiar with it at all. (Pic related it’s my SS) -Thanks!

Hey guys, just wondering if anyone on here knows if the ls1 harness is the same schematics as the ls2 harness. I know the plugs are different, but is the pinout the same? I'm converting from D580 coils to D510C. Purely to tidy the engine bay and maintain an OEM level of appearance. I have ls2 pigtail connections to suit and am adequate at making my own harness. Just need to understand the harness and if the pins at the plugs are all going to the same spots! Pic showing what pigtail connectors i have purchased. Thanks

Long story short, took engine out, did a bunch of mechanical stuff(heads, cam, injectors, intake). Had ECM rough tuned for trip to dyno. Tried cranking it, I get 1 click, and power dies to to car. All fuses and relays check out. All grounds are grounded, all but intake sensors are in. Anyone know what's up. Battery and starter both tested good

got a 4.8 in my s10 its been running like garbage occasionally sounds like fireworks coming out the exhaust I've changes intake manifold gaskets, rod knock sensors, plugs,wires, coil packs, and fuel pressure regulator but it's still slowly getting worse fund's are limited so just wondering if yall had any ideas I have a video if you need

I have a rtd device and I have the file for my new tune on my email. I need someone with hp tuners to send me the file to my rod so I can put it in my 2004 gto.

I have a ls1 5.7 fresh rebuild Sloppy stage 2 cam 102mm tb K and N intake Cat back back no restrictions Shortyheaders High pressure oil pump

TRANSMISSION 4l60e fresh rebuild 2500-2800 stall Corvette servo Shift kit

So I have a 3800 v6 convertible I bought kinda for parts and I needed a set of wheels but the motor is locked so I got it cheap. So now I’m getting it out of my yard and before I get rid of it I want to know what all I can take off of it for my 01 trans am ws6? So far I’m taking all the headlight stuff and keeping the trans but I’m just not sure what all is a good grab , any help appreciated I’m gonna start tearing it apart Tom

I’m ls swapping a v6 fbody camaro and was wondering if the lt to ls k member adapter plates work or if there’s any modifications you can make to a lot k member to make a ls fit

Thinking about building a street / sleeper truck , my brothers has a 2001 Silverado 2wd 5.3 that has a bad tranny , been doing a little research and was thinking about buying it , then pull motor freshen it up and doing a single turbo set up on it , anyone have any experience turboing ls1 and what turbo kits are good ?

Context 1 have a 96 Silverado im planing on engine swap with a Is1, my ideal transmission would be a t56 from a corvette. My plan is to transfer the transmission, torque tube, and axles etc, to my truck. Im hoping it will help balance out the weight distribution and help keep the wheels more planted. The question is would the transmission mount properly to the engine? What other issues could i run into? And what advise can you give me?

Is the 5.7 out of a 95 suburban considered an LS1 or is it a late model LT1?

So i’ve got a scion fr-s with a blown engine and im not trying to swap in another boxer engine into it due to the fact that these engines get ran through like nothing after adding any type of boost or power. i’ve already got a 5.7 ls1 from an old chevy box truck, but i was wondering if there was any tips on what trans i should buy on a budget(5spd or 6spd), and if there’s any ls1 wiring harness/ecu i could scrap and reuse for the swap. And I was also concerned with any preventative maintenance/upgrades i should do before considering the swap. I plan to run this thing as stock as possible until an inevitable rebuild.

What clutch and flywheel should I use for my 2002 t56 from a Camaro on my 2002 5.3 gen3 lm7
