The LS engine was designed & platformed from the SBC , even chevy admits that. It is & always will be a chevy designed & built engine.

Really, seems you've been proven wrong by more than one person and your still saying the same crap. READ and COMPREHEND what's already been posted. Show me where the chevrolet motor division says in print that they design and manufacture the LS engine. Speed equipment companies that also print that it's a chevy engine, aren't proof, they also don't have it correct. FYI, many speed equipment manufacturers that are knowledgeable also list it as a GM engine, and list SBC separately.

Care to explain about your source that you claimed the LS engine was designed in the mid 80s, still waiting for that source.

Before you regurgitate more mis-information maybe you should do some reading about the LS engine and where it was made, who it was designed by. It's painfully obvious you don't deal in facts, even when they're presented right in front of your face.

There is only one thing shared with a SBC, and that's bore spacing, NO PARTS interchange between the 2 engines. The LS engines are as close to a SBC as a ford small block is. IT NEVER HAS BEEN A CHEVY ENGINE and no matter how you try to protest and say it is, it's not!!!!!

I deal in facts and have shown printed matter that clearly states the LS engine was designed by GM powertrain and other than chevy using it in some of their offerings, they have NO connection to the design or manufacture of the LS engines now or before. Your repeatedly saying it, won't change the fact that it's a GM design and manufactured by GM powertrain, not chevy.

What you fail to understand it may say GM powertrain but it is in the chevy plant & if you want to do the build your own engine LS you go the the Chevy plant to do just that. so just by placement the LS is a chevy build engine. You can call it any thing you want but all know the LS is a chevy engine. It doesn't matter if you want to call it GM powertrain or not but the only mgf. of engiens for the last 10 years has & is been chevy, you have to remember that chevy is GM. Period........................ Now you read & comprehend. Plus if your not aware it takes about 10-15 years to get an engine certified anymore when it's a complete new platform & the LS started it's design in the late 80's . I missed by a few years but it was by the old lit. that I use to get in the dealership talking about a new designed engine coming for the Corvette , it started out as a multi-valve engien but it became to much to do so the switched to what we have now in the LS engine family being the veri-valve timing . I got lit. on that in 87-89 when I was still working as a service mgr at the chevy dealer.

I just typed in wikapida for the ls engine & when you go through th LS seris of engines when you get down to the LSX376 engine it states the LSX376 engine built in the Chevrolet performance dept this engine is also of similar design the Harly Earls 1954-56 SBC designed engien, plus that the LS series engine was designed for all the rear wheel drive vehicals only & that the LS1 was designed for the Corvette in 1997 for the Corvette alone & then later used in smaller sizes fro the trucks & SUV & other rear wheel drive vehicals through out the world. Now if being designed in the Chevrolet Performance design center doesn't mean chevy engine then What does????? Chevey is GM & GM is chevy. 1 in the same . Everyone can go the wickipida to see the same thing. Now there your proof. That is direct from Chevy saying it's a Chevy engine. Done Game Set & Match. !!!!!!!!!!!!!!!!!!
