If you have an automatic transmission SS then you have L99

If you have a manual transmission SS then you have LS3

LS9 is a supercharged engine

LS3 and LS9 are two different engines. The LS3 is a 376 cubic inch with 426 horse power engine. The LS9 is a 350 cubic inch with 350 horse power and 425 lbs/ft torque.


You can't make an LS3 into an LS9. You'd just have to do an engine swap

Not exactly. The original LS9 (used in the 69 and up trucks was N/A. Then later the LS9 got a roots blower thrown on it.

Yup.

Here's what I am doing...

I have an L99 that I am converting to an LS3 (Removing all the active fuel management and variable valve timing). This requiers a new CAM, so I am using the LS9 Cam and Valve Springs. I will add the Edelbrock E-force Supercharger, which is very similar and a lot less expensive as the LS9 Supercharger. Ultimately, I will have a "mock" LS9 (the new one, that is).

The LS9 has:
Dry Sump oil pan
Oil Pump and system so hard cornering wont rob engine of oil.
Oil Squirters under the piston.
Forged Crank and Rods.
High temp valves

From what I was told, the heads, pistons, pushrods, and block are all pretty much the same except for some of oil squirters.

That is what I did too. LS-9 Cam and E-force Supercharger. It makes for a very torquey ride.

How are is your rear end holding up? That's my biggest concern.

PS- your 69 Camaro is so amazing. That is my dream Camaro.

Glad you like the '69. It has been a part of my family for a long time.

1 year of driving with the E-force and the rear end is still fine. I did loose a driveshaft bolt shortly after the supercharger install but the replacement bolt/nut was installed carefully (by me) according to the GM manual and has held up just fine. It all depends on how you drive your car. If you add slicks and hit the track then all bets are off and I assume the rear end would fail. Drive sanely on the street tires and it should last just fine.

Am I missing something here? The LS9 is a reworked LS3 with a supercharger. Its 376ci (6.2L) that puts out 638hp. I think youre thinking of the LS9 from the '70s!!
