Not that this has anything to do with this thread, but someone brought it up, and I'm bored...
The 1917/1918 -288ci, was the first overhead valve, water cooled, 90° V8, produced by Chevy, and made a whopping 36hp. Chevy wouldn't offer another V8 until 1955, starting with the first gen 1 small block 265ci, and the first big block not coming out until 1958 in 348ci
List of stock size gen1 and 2 small blocks that I know of (not including aftermarket sizes, anything bored out, or stroker kits):
262, 265, 283, 302, 305, 307, 327, 350, 383, and 400.
Gen 1 big blocks:
348 and 409
Gen 4 big blocks:
366*, 396, 402, 427, and 454.

And the Gen 7:
496.
Dont know much about LS or LT series, don't want to, Haha.
The most I know about the straight 6 that everyone here is talking about, is that it ran from about 62 to 88, and that in these years it was in its 3rd generation.
List of gen 3 straight 6 that I know of: 194, 230, 250, and 292.
I personally own a 250, 3 -283s, a 305, 6 -350s, a 454, and 2 -378s.
