How do you code the LS3/480 I purchased from The GM Performance Division ?
Bradford, the LS3 480 horsepower is really just a LS3 with the 219/228 degree duration Hot Cam instsalled. All other specs are identical to the LS3.
Have a 89 Chevrolet iroc Camaro with a 5.7 liter in it what would be the best swap,have a 700r4 automatic transmission
The 1989 Iroc is destined to become a classic. With LS swaps, it’s generally easier to find newer engines with lesser miles. Gen. 5 engines require considerably more effort to install though, so we would recommend a Gen. 4 LS3. The NAL-1941986 variant with the Hotcam is a nice upgrade that works well with the stock converter. It’s also easy to use the installer kit NAL-19354330 that has theh harness, ECU, and electronic gas pedal required to actuate the throttle body. Motor and transmission mounts are common and should make for a relatively swap and add another 240 horsepower to the IROC and run like a dream.

I have a 94 Chevy cab in a half Dilley with a 454 and want to change to a LS motor what is the best one to buy.thanx K B
There are 46 Gen. 3 and 4 options. Ideally it would be best to get a larger 6.0 or 6.2L engine to get the extra torque out of it. That being said, even a 5.3L can be surprisingly strong. Some of the 6.0 and 6.2’s in the cars used a short runner intake manifold. The truck versions were very similar except had tall intake manifolds with long runners to produce more low end torque. They also had cams that were designed for more low end, but we’d recommend the installation of a SUM-8718 torque cam while the engine out to make whatever you have an absolute monster. Take a look at the following guide. It breaks out all the engine codes by displacement and where they were used. From there, each link gets into engine specifics. A Gen. 3 engine is almost always a little more simple because you don’t have VVT or AFM. Gen 4’s were all over the map with these features, but VVT and AFM delete kits are common and take all the headache out of anything you choose. Keep in mind, no matter what you get…you will want to get the matching ECU, wiring harness, and throttle pedal if equipped with Drive-By-Wire. The Customer Help section has a variety of spec articles and upgrade articles that cover everything you need to determine the direction you are going. Just enter engine codes etc. into the search bar and these helpful articles will popl up.
Add fuel injection to the 454 and skip the LS swap. The 454 is a way better engine hands down.

Anyway someone can help me out? I have an 05 Silverado ext cab 2wheel drive withe the 5.3 vortec. I believe I just spun a rod bearing this past week and I am looking into replacing the motor. What I am confused about is what motor I can put back into it. I’d like to stay with the 5.3 it’s an lm7 vin “t”. Can someone tell me which motor I’d be able to get and be able to drop right in without having to change anything else. For instance does it have to be the same vin “t” motor to match up. As far as my understanding I can put any 5.3 in it out of a Silverado suburban Tahoe or Sierra is that correct? Any advice would be greatly appreciated. Thanks

CAN I USE AN 07 INTAKE WITH STEEL FUEL RAIL WITH A L59 BLOCK?
As long as the intake manifold you are using is designed for cathedral port heads, you will be fine. L59’s were actually used from 2002-2007 to begin with.
Why in this guide it shows 5.3 2005 and newer with a 8 th dig C as being a ls4 transverse fwd vehicle……many of the trucks and SUV 2010 and up 8 dig C is a 5.3 rwd units ….something does not smell right …
Have 2010 5.3 flexfuel blown motor, found 2006 5.3 flexfuel if I use intake everything be okay
ARE lm4, l33 ,lh6, lc9, lh8, lh9, bare blocks interchangeable
You are in luck. When it comes to blocks, they are basically all interchangeable as long as you use the bore size that fits your rotating assembly. That being said there are a couple differences that are important to note. The Gen. 4 engines moved the knock sensors from the valley to the side of the block. They also moved the cam sensor from behind the intake to the front timing cover. There are adapter harnesses to fix either situation.

I just sold my 97 Tahoe so as to use money to buy a 91 Pathfinder 4×4 and it has the 3.0 or 3.1 V6 . I’m wanting to remove engine and whatever else I have to, so I can install a V8 drivetrain. Should I use a Toyota Tacoma V8 or can I use some good ole American muscle V8 like LM7? And what should I use as far as transmission goes for the LM7/5.3-5.7? Would Pathfinders transmission ,rear differential and driveshaft hook up to the LM7?

I have a 99 silverado 2500 2wd with 6.0 w/ 289K. Wanting to rebuild another 6.0 but use 862 heads to bump up the compression, but, if at all possible not be relegated to using 92 octane. I understand that even with the higher static compression that the cylinder pressure can be managed by cam timing and bleeding off some of the pressure. Bottom line, does anyone have any recommendations for the kind of cam to use? I will be doing some porting work in the heads to increase flow.

I have a 2011 GMC Canyon with a 3.7L inline 5cyl. I woild like to swap to a LS V8, any suggestions?
I have a 1996 Tahoe with a 5.7L something. The Gen III title above (Gen. III LS Engine Upgrade Guides & Specs (1996-2007)) specifies 1996 but none of the rows underneath start at 1996. The 8th digit of my VIN is an “R” so I’m not sure what I have. I have 350K miles on this motor, it’s tired, leaking like a sieve and needs to be replaced. Any recommendations? This is about ease of replacement, not looking for 400+ hp although wouldn’t reject it. 🙂
Do a VIN search. You probably have a L31 engine. These are NOT part of the LS family. You can get an L31 on ebay for cheap. Do a youtube search to find out what upgrades you should make before installing it.
I was looking to upgrade my 1972 K5 Blazer with an LS motor and transmission. Not really looking for a 5.3L but something with a little more punch. I was hoping for something stock with at least 500 HP. Your thoughts or suggestions would be greatly appreciated! Thank you.

Yes, BUT you may not have access to the boost settings that are available to the Vette e67 ECM.
