I edited the old Big Block article, prior to its being merged with this one.

In a nutshell, the term big block, as oppossed to small block, refers to the physical dimensions of the block, NOT the displacement of the cylenders. Thus, GM produced a 400 cubic inch engine in both big and small block form.

An important distinction if only because it is a common confusion. The current Z06 corvette, at 7L is a small block, while the mid-60s Olds 425, at 7L, is a big block.

Unglobal usage[edit]

I understand this is not really "international" in terms of the definition of the engine block, but as far as I know, I haven't heard the term "big block" or "small block" in reference to anything besides American engines. Most of the foreign engines have a displacement smaller than 5.9L, so they would all be classified as "small blocks". And the only engine manufacturer to ever really focus on any differentiation appears to be the "big 3" American manufacturers. (Note that I did not add this tag; this tag was added without any discussion being added as to why.) Zchris87v 21:11, 26 October 2007 (UTC)

So lets take the tag out of the sections dealing with small block and big block. However, engines throughout the world have cylinder blocks, and this article's name is generic in that regard. Gene Nygaard 17:20, 3 December 2007 (UTC)

NB the term "cylinder block" is not common in the UK, where "engine block" is preferred. —Preceding unsigned comment added by 92.25.195.0 (talk) 10:55, 9 June 2009 (UTC)

While true, it is impossible to satisfy every case. "Engine block" is noted in bold in the lead paragraph, and "Engine block" redirects to this article. I think the bases are appropriately covered. Huntster (t@c) 10:58, 9 June 2009 (UTC)


This article is absolutely rubbish. It's entirely about US marketing of engines as big/small block (which is irrelevant anyway, they both work the same way!) and needs to focus on the cylinder blocks purpose, design, and construction. The existing article should be split into two entries, one for "small block" and one for "big block", and none of this content should be under "cylinder block" or "engine block" Awaken (talk) 11:03, 6 October 2009 (UTC)

IMHO it's a reasonable article, and the "small block" / "big block" sections should be kept in the same article. However whatever this article is about, it's certainly not "cylinder block" in any objective sense. It needs a rename, and we ought to create a new article on cylinder blocks.
So what should this rename to? US V8 big & small block engines? Andy Dingley (talk) 23:21, 21 November 2009 (UTC)

Engine block =/= American V8[edit]

Are you people serious? A wiki page on "engine block" that is predominantly devoted to American V8s? This is one of the worst pages I've seen on Wikipedia. 61.69.26.101 (talk) 01:28, 27 March 2010 (UTC)

WP:SOFIXIT applies. 8-) As noted above, I don't think this is a bad article, just not the article topic the title suggests. A split or rename to move the US content under a new name, then a new article from either the existing intro or entirely from scratch.
WP always has trouble with broad-scope articles. Andy Dingley (talk) 09:27, 27 March 2010 (UTC)

Monobloc engine[edit]

There's a discussion at Talk:Monobloc engine that's likely to be of interest. Andy Dingley (talk) 11:40, 27 December 2010 (UTC)

Casting Methods[edit]

I would really like to see some discussion inserted into this article regarding some history and timeline of how the blocks were actually cast.....sand cast, lost foam, current practices, advantages, etc. Articles on casting of various metals on Wikipedia just mention 'automotive uses' in passing and don't really explain anything in detail. Can someone out there in Wiki-land supply this info ? H2RICK (talk)
