It produces 303 HP @ 5600 RPM & torque is 323 (lb.-ft.) @ 4400 RPM.
Fuel economy is 18 city and 27 highway (in the Impala).
Seems like a good comprimise to the LS2 (if GM would consider a V8). Its all aluminum, uses cylinder heads originally developed for the Z06, gets better fuel economy, and it produces more power & torque than the Ecotec turbo. And it would most likely be within GMs strict tolerances--LS2 fitment is too tight by GM standards. The LS2 adds 200 lbs to a base Sol's curb weight, the GXP adds about the same weight gain over the base. So I'm guessing that a Sol with the 5.3L would weigh less than the GXP.
I have 2 questions.
1. Will it bolt up to the stock drivetrain?
2. Would this be a good comprimise to an LS2?
Active Fuel Management™ for an EPA estimated 18 city and 27 highway MPG
Aluminum Construction — all major castings in the V8 engine, including the deep-skirt engine block, are made of weight-saving aluminum. Casting from aluminum contributes to a stiff engine structure that helps ensure smooth operation
Electronic Throttle Control (ETC) — ETC replaces the mechanical link between the accelerator pedal and engine with drive-by-wire electronic control. This allows for remarkably smooth and precise acceleration
Polymer-Coated Pistons — pistons are coated with a polymer material that reduces engine wear and contributes to quieter operation
Cylinder-Head Technology — the small block V8 cylinder heads were originally developed for the Corvette Z06. Their pent-roof combustion chambers and flat-top pistons deliver high horsepower
Composite Intake Manifold — the composite intake manifold design allows the small block V8 to deliver high levels of torque at low and mid-range engine speeds, while still delivering plenty of airflow for peak engine horsepower

This is a pretty specific question that only a few could answer...I would almost gaurantee modifications will be needed to the engine compartment...could it be done...yes at a decent ammount of savings over LS7 or such engine...probably not!
Isn't this V-8 a transverse mounted engine, designed for front wheel drive? If so, there is a substantial amount of engineering time to adapt the engine for the 90 degree change in orientation needed for rear wheel drive?

Okay...why do you need it? I'd bet the 2.4 turbocharged would beat that engine. And you could later rebuild the 2.4, run more boost, and really embarrass that 5.3L.

WHAT!? You gave it 3 hours for response... in the middle of the day. Why not exercise a little patience.
We've all learned patience waiting for our Solsti.

yeah this is the front wheel drive version in the impala ss however the 5.3 could also be found in a rear drive configuration in a truck.
I didn't know that there was a RWD version of this block. I assume that the reason this hasn't been tried in a Sol is because it isn't as common as the LSx V-8s, nor does it have as many aftermarket performance parts availalable.

For the same reason folks want a Mallet conversion. Except this would be from GM, weigh less than a GXP, get better fuel economy, more HP, more torque, V8 rumble (as American as apple pie), etc, etc, etc. Would be a modern AC Cobra.

5.3 L LS4 V8 in a 2006 Chevrolet Impala SS.The LS4 is a smaller 5.3 L (325 in³) version of the Generation IV block. Though it has the same displacement as the Vortec 5300 LH6, it differs in that it has an aluminum block rather than an iron one and it uses the same cylinder head as the Generation III LS6 engine.
A version of this engine is adapted for transverse front-wheel drive application. In order to fit into the smaller engine compartments designed for V-6s, in the front-wheel drive Pontiac Grand Prix GXP, for instance, the LS4 engine block had to be shortened by one inch. Displacement on Demand is also used. Output of this version is 303 hp (226 kW) and 323 ft·lbf (438 N·m).
Applications:
2006 Chevrolet Impala/Monte Carlo SS
2006 Pontiac Grand Prix GXP
BTW: The Impalla SS tips the scales at a hefty 3,712 pounds
And it does 0-60 in 5.7 seconds! And thats front-wheel drive.

I see your point. I guess you and I come from different schools of thought...I'd rather have little displacement and boost it instead.
I think it's an interesting idea. With enough money and/or elbow grease, I'm sure this can be made to fit and mate the bellhousing.
And if it does in fact weigh less, than it would be a pretty nice alternative. To make it run, I'd guess you would need a new standalone PCM. (What is Werks doing for their LS conversions?) If you do need a standalone, I think getting the displacement on demand feature may be difficult to implement. Even with a reflash of the Sol's PCM you'd probably still not be able to accomodate DOD.

I have this engine in my 05silverado p.u. Its also in the new grand prix , monte carlo and i believe the impala , It replaced the tried and true 350. Runs more h.p than the 350 but less torque
I think this is a great idea! I'd love to have a Mallet conversion, but I don't have the money laying around for such an expensive upgrade. I'd like to see a conversion kit developed that I can do myself with a engine that can be easily procured from a number of places. Although, I'd probably wait 3 or 4 years until my warranty expires.
One of the things I like about this is balance. The 5.3 application adds a lot of hp and even more torque, but no so much that the engine or drive line is overstressed. Hum, deep rumble, gobs of torque, and reliability and economy, sound like a winning package.
What about the transmission? How hard is it to mate the 5.3 to the existing transmissions? Or would it be better to use the future 6L80 6-speed read drive manumatic transmission?
OK all you entrepreneurs, I encourage you to get started on a conversion kit ASAP!
