Bringing this thread back up - I think good to refresh the info and I wanted to add some info I got from a vendor that does LS swaps.
New LS3 530HP Turn Key swap. Full factory function - cluster, AC. 30 month / 50K Mile warranty Dyno tuned and tested using HP tuners on GM E38 Engine ECU
$30K
Go from the LS3 to an LS7 with 625HP for $35K.
These are new crate engines from Blueprint.
Expect from a DIY - $15K minus the engine from the vendor I spoke to. So, if you were to start off with a used motor - the cost would be considerably less that the new engine turn key solutions I refer to above.
If anyone wants the vendor info, feel free to shoot me a PM. They were referred to me by the President of an aftermarket components company that makes very high end parts. Take it FWIW.

I think it's something worth considering for the huge performance, and warranty coverage. Maybe some peace of mind that you don't have to worry about some of the inherent M96 issues that remain even after you have spent $20K+ on a rebuild...

If you say the exhaust weighs about 50 LBS and could be used on both engines, call it about 400 LBS.
An LS3 with accesories is 418 LBS https://www.chevyhardcore.com/featur...-dyno-results/GM 6.2-liter LS3 V8:
- Length: 28.75 inches
- Height: 28.25 inches
- Width: 24.75 inches
- Weight: 418 pounds (with accessories)

My question is: where is the weight located in each engine? It seems illogical to me that a V8 engine weight is as low as an opposed 6. I guess if you just want a drag car ok, but I'll pass. I didn't spend anywhere near $30k, have an unmolested car that still handles as it should with more HP and torque than factory. I prefer not to own a Frankencar. To each their own...
I have read various accounts that the M96 W/Exhaust is around 450 LBS.

I don't know what a Frankencar is - it is not a stretch though to think that a 996, with a properly executed LS will outperform the M96 in EVERY measurable performance, reliability and cost of ownership metric.
The drag car thing is complete bull ****..you have no idea how the car would handle with an LS. I would hazard a guess...my car with an LS would absolutely smoke your car with your M96 on any track or road in America - straight, road course, rally or hill climb.
And thats not to say that the swap is purely for performance, its to highlight a point - the "if you want a drag car" statement is silly.
How much did you spend, ballpark would be fine and does the engine builder approve of your engine for track use ? What is the rated HP/TQ and did the builder provide a dyno sheet to backup the claims ? Does the warranty match the 30 month / 50K mile you get on say a 530HP Blueprint engines LS3 ?

Sounds like the weight gain is inconsequential considering the power gain. Someone's doing one of these locally, I've only seen the photos. Now that I've gotten the second shot, it's time to introduce myself and see if I can get a look at how it's going.

The only thing I don't like about the LS swap is the idea of cutting the car.
When someone develops a electric crate motor drop-in for the 996, they can have all my money.

Apparently you missed the part where I said "To each their own..." I did not intend this to be a "my car is faster than your car" issue. I outgrew that in high school.
You did not answer the question of how high up is the weight of a V8 in a 996 compared to stock and what, if any, consequences this might present in handling. Keep in mind the old saying "the guy/gal who is quickest through the corner is quickest down the straight." I could care less if an LS 996 would out run my car on a track. If I wanted to race again I would buy a "proper" race car.
As for the rest of your questions:
#1: A reasonable amount to me
#2: Not a track car so I don't care(see above)
#3: Plenty of HP/TQ
#4: Yes
#5: Don't care
Calm down. I was not attacking nor besmirching your previous post. In fact I considered an LS conversion until I realized the consequences/costs of such a modification.

You don't have an unmolested car - you have one with a rebuilt motor, which is great, not a negative, a positive. A "molested" 996 - to use your term - can be a MUCH better 996 than came from the factory

Cool
I will infer this as a no.

Great !

This is one of the things making me pause my plan to LS swap another vehicle.
Right now I just don't have the time required to solve these known issues.
Engine swaps often fail/stall because of all the unknowns.

I wouldn't mind eventually having an electric car for local daily driving, but it sure as h#(( won't be my 996.

That was one thing that bothers me...the other is inoperable gauges, power steering, AC, TX emission issues.

I'll drive my gas powered 996 until I die, or I can't purchase fuel.

AC, CEL, gauges (CAN Comms) are good with the setup I mention, PS is a conversion to electric (same as Cup), which I think would be a worthy change on an M96 FWIW.
