New LS3 Create Engines
"The LS3 Family – Three New Crate Engines
The LS engine family is expanding once again. This time, we have three powerful new engine offerings to enhance the choices for late-model performance enthusiasts, muscle car and street rod builders, and racers of all stripes.
The three new engines – the LS3 6.2L, LS376/480, and the LS376/520 – continue the LS tradition of breaking new ground for efficiency and performance from a pushrod platform engine.
The LS3 kicks out 430 horsepower and 424 lb.-ft. of torque. The LS 376/480 is an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower! The LS 376/520 is equipped with an aggressive camshaft and GM Performance Parts' exclusive carbureted intake manifold. That's two simple upgrades that add up to 520 horsepower – a 90 horsepower bump over the stock LS3.
Available in early 2008! "

This should make up for the challenges of very peaky power with the L92 heads.
With new engines like these coming out, not sure if building an engine to go racing is needed.

Nice! And the best part is it looks like the LS connector is a plug and play solution for LS1/6 upgrades! No changing reluctor wheels!? Anyone have pricing info on the 480?

This is great news this is going to be the next big thing for anyone looking to add "cheap" power to there tired C5. It's basically an all bore 383, a good head and cam should get you over 500 rwhp.

So Joel, did you see the ported L92s make "Peaky Power" on the dyno?

They are very close to plug and play in a C5 with reluctor change, if you use the factory intake and fuel injection.
At PRI they were showing the new fuel injected LS3 that includes everything you need to put it in stand alone, without supporting electronics. Includes MAF, TB, two 02 sensors TB, electronics module and even a electronic gas pedal to drive the TB. Aimed toward hot rods or 70s-98 Camaro etc..

Question about plug and play in a C5 Z06, or actually, my Mosler which is LS6 and 2004 Corvette computer. Theoretically one of these LS3 motors could drop right in? The real question is - when I go looking for more power, am I better off building up the LS6, or going to something like this? Inputs appreciated, I want 500 RWHP reliably.

So when folks say plug and play (into a C5), wouldn't that also involve the different reluctor/computer issues? I have been aware of the different reluctor between LS6 and LS7, but when I hear folks state "plug and play into a C5", I get a bit confused.

Once that is back together a few simple wiring harnesses and minimal transposing of parts gets it done.

It would be interesting if someone came out with a "black box" that would allow you to use the 58 tooth wheel with the older computer, but it would take some doing, apparently that seems to be what GM is claiming with these new controllers.
We've developed a way to take the guesswork out of an LS engine swap – true plug-and-play controllers for LS2, LS3, and LS7 crate engines.
Coming in early 2008, the LS controllers will allow you to simply plug the factory-type harness connections into the new controller and start the engine – no recalibration or tuning is required.
Best of all, the new controllers are adaptable to any vehicle fitted with one of the previously mentioned engines – from late model Corvettes, GTOs, and F-cars to vintage muscle cars, street rods, and off-road vehicles.

The problem with the 58x reluctor is it is not any even percentage of 24-- so it has been explained to me. 58/24=2.41666-- If it were 48 tooth -probably..
GM's solution is not either/or. It is based on the newer MSD spark system which is stand alone 58x. It cannot integrate into the GM suppled C5 or early C6 PCM which does spark, fuel and lots more. MSD does make a limited capability 24x spark box and a separate 58x spark box. GMPP has integrated the fuel function for roughly $1k. The GM on board PCMs are so high powered and all encompassing they cannot be converted to 58x from 24x or visa versa.
However once you change the reluctor trigger to match the controlling PCM, anything is C5 possible. We provide 24Xed LSs as 2,3,6,92 or 7 based, usually stroked. Callies and other crank manufacturers provide either reluctor to spec.
The path we would like to see GM take is to offer a choice of 24x or 58 installed reluctors. Maybe next year. GMPP, has come a long way.

I do belive the new GMMP PCM is the MEFI unit, and could probably use the InGenius software for calibration. Same as the new MSD units.
UMI Racing has used these units in some off-road applications for awhile

While on crate engines, not sure if everyone has also heard that GMPP is also bringing out a new limited edition "anniversary 427", a modern re-creation of the ZL-1 427 from the sixties. They expect to only make 427 of these engines!
