Lsx = sbc?

(I previously posted this on the train, but barely got any responses)

I've gotten into an argument with somebody that is referring to the LSX based engines as SBC, I however don't believe they should be put into the same category as SBC, since they pretty much have nothing in common except both being pushrods. I'm just wondering what you people think/have read, are the LSXs motors SBCs, or are they just plain and simple LSX blocks with the moniker SBC being reserved for the yesteryear engines?

Its still a small block so......

Is that really enough to consider the LSX an SBC though?

Does that mean the new sohc/dohc ford modulars are small ford blocks?

They are not the same.



The Chevrolet small-block engine is a series of automobile V8 engines built by the Chevrolet Division of General Motors using the same basic small (for a V8) engine block. Retroactively referred to as the "Generation I" small-block, it is distinct from subsequent "Generation II" LT and "Generation III" LS engines.

Production of the original small-block began in 1955 with a displacement of 265 cu in (4.3 L), growing incrementally over time until reaching 400 cu in (6.6 L) in 1970. Several intermediate displacements appeared over the years, such as the 283 cu in (4.6 L) that was available with mechanical fuel injection, the 327 cu in (5.4 L) (5.3L), as well as the numerous 350 cu in (5.7 L) versions. Introduced as a performance engine in 1967, the 350 went on to be employed in both high- and low-output variants across the entire Chevrolet product line.

Although all four of Chevrolet's siblings of the period (Buick, Cadillac, Oldsmobile, and Pontiac) designed their own V8s, it was the Chevrolet 350 cu in (5.7 L) small-block that became the GM corporate standard. Over the years, every American General Motors division except Saturn used it and its descendants in their vehicles.

Finally superseded by GM's Generation II LT and Generation III LS V8s in the early 2000s and discontinued in 2004, the engine is still made by a GM subsidiary in Mexico as an aftermarket replacement. In all, over 90,000,000 small-blocks have been built in carbureted and fuel injected forms since 1955.

bank split, bore spacing, and number of cylinders is about all that's shared

Both have 4 too many cylinders so I don't give a shit.

I call them small blocks.

Motors have been advancing forever. Block size is still the same. They are either big or small (when it comes to Iroc's hated V8's).
