Does anyone know the history of the LS2 engine. When was it first used and what is it used in. You see terms such as 'small block' and 'large block' mentioned in some documents in regard to V8 engines does either of these terms relate to LS2 engines? I think I have seen referance to over 8 million engine units in the USA alone, is this true?
Small Block refers to an engine smaller than 366 cubic inches. That means less than 6 litres is small block. Above 6 litres is classed as a big block.
So an LS2 is erm.....dubious to classify.
Truth is the Yank musclecar guys would say it was small block due to association with the definately small block LS1 (~5663cc???) and the fact that it is ~5996cc (not the exact figure but you get my point) and thus, marginally, under 6L.

Whilst technically both the Ls1 and 2 are small block engines you can actually get 427 small block also. (Harryoz for one)
I think the small block description is now reserved for all the pre Ls Chevy engines which have been around since the 60`s and is probably the most popular engine ever produced.
Also the `old SBC` had a much more distinctive burble due to a different firing order to the Ls range.

yep chrisjez is right. Smallblock has nothing to do with displacement but rather block size. The entire LS series is a small block. The bigblock I can still be had in 454, 572 etc cubes. Basically taller deck and bore spacing.
Ls2 first saw light of day in C6 corvette. Then caddy cts, holden, chev trailblazer etc.
Its now history
Long live the smallblock 6.2L ls3

My Ford Cleveland is also classed as a small block so it's not just a GM thing.
Let's just say SB/BB are subjective terms depending on your description.
From wiki
http://en.wikipedia.org/wiki/Small_Bl
Big block
A big-block engine is a North American V8 in a family of engines which generally have greater than 5.9 L (360 cubic inches) of displacement;
Small-block
A small-block engine is a North American V8 in a family of engines which generally have less than 6 liters (360 in³ of displacement, although some derivatives have grown larger (up to 427 in³, 7.0 L).

Just noticed the Wiki experts also claim the definition as "The size of the distance between the cylinder bores" so it's not technically anything to do with the actual block size (of course you would need a bigger block to make the distance between the bores bigger...LOL) but pfffft!
This is all just pedantic shizzle! hahaa

Get with the GM program dude.
Going by displacement is a general rule for labour voters. You know, those people with less brain cells than children.
With ford and gm there were 2 block families. As you say based on bore centre spacing, and also deck height. But really they were 2 blocks. One larger than the other.
Of course one was then called the small block, which in GM format ran from 265cube right up to 400cube. Big blocks in gen2 ran from the 396 up to, god knows what these days with the taller decks. North of 600 cubes anyway.
Thats how it was and always will be. With the Iron Gen2 small block being replaced with the Gen3 LSx series and from LS2 the Gen4 stuff which also includes the LS7 and LS3.
You have to use wikipedia properly. http://en.wikipedia.org/wiki/Chevrolet_Big-Block_e...
