LS3 is rated for more horsepower. also mods like a supercharger show higher gains then the l99.

The L99 is derived from the LS3 with reduced output but adds Active Fuel Management (formerly called Displacement on Demand), which allows it to run on only four cylinders during light load conditions.

This mill's similarities with the other Camaro V-8 are extensive: L99 for example, its block, cylinder heads, crankshaft, and connecting rods-along with the intake manifold and throttle body-are all shared with the LS3.

Tune an L99 and you have an LS3, just with an auto transmission which, in reality, makes it faster than an LS3.

L99 also have a bit more torque down low than the LS3.

Sourced from a previous thread on the subject. Search around on here or even type into google. you will get all the info you need.

Stock for Stock if I was going up against a 5.0 I would want a LS3. If i was going to mod then I would take a look at the L99 as the auto tranz is a sneaky lil thing on the drag strip. If all you want to do is plant your foot and go. For a novice driver it is easier to get decent 60ft times with the auto tranz. If your doing a highway pull (not that I support that) I then again go with the LS3... I dont know how the L99 sport mode works or if you can get in the right RPM range to be where your powers at. L99 people would have to chime in on that.

Also something I just read... If you have a L99 car and and do bolt ons your going to have to get a tranz tune because the tranz reads off the maf and determines tq specification based on that calibration... ill see if I can find what I am talking about.

Thread on this matter... Again not a L99 owner so they will have to chime in on this.

sorry i forgot to ask so which motor is faster with tune? l99 or ls3? with really good drivers on both sides?

[BigBlock427]

really depends on the tune and tuner. you can convert the L99 into LS3... and keep the auto tranz.. however if your a good driver then there is no need and you can just start with the LS3

[BigBlock427]

Read my first post i added some info to the bottom. Hope this helps !

you are going to open a can of worms here. Some swear that the auto will be faster long term and others the manual will be faster long term.

Personal opinion - if you aren't good at driving stick run with an auto. If drag racing, go auto. For fun, go stick. If you are a good stick driver, then nothing to worry about.

I opted auto for two reasons:
I had 3 sticks prior to this and got sick of the shifting in traffic and prefer the ease of letting it do it for me
I will convert my L99 into a LS3 eventually and still have the auto tranny

[BlackSS_13]

thanks for the info is really helping and yea i know just want to get knowledge from both sides i have an ls3 but a buddy of mine has a l99 you know why im asking now

[Bad70supreme]

The ls3 is faster hands down, put out more power at the crank and at the ground. Most people cant launch very good and results in losing to an auto. The auto with boltons and tuned will be a much more constent car but not faster. I went with the manual trans LS3 and if you spend enough time behind the wheel you will learn to drive the doors off it.

Thats what I was going to say... Haha but ohh well! I believe that each have there place... just think the LS3 should have been offered in stick or auto...

From a pull (DONT DO THIS DISCLAIMER) then the LS3 should take the L99...BUT if you miss a gear... slow in a shift... then the L99 is going to wave as it walks by you.

If he converts to a ls3... then your going to have to work harder to out drive his computer.

Going down the road, sport mode would allow you to hold the car in whatever gear and bring up the rpms to where it needs to be for a good initial punch when you slam the go pedal just like the LS3.

Its just that when you use the shift buttons you have to time it just right because there will be a short amount of time in between when you click the button and the actual shift, otherwise you end up bouncing off redline.

^ Really huh didnt know that. thats pretty cool!
