V8 Chevy's go back to at least 1917 as far as I know, but not in the same form as small block Chevy's.

Not sure, but thinkin the 283 small block goes back to '55 and was rated at 1HP per cubic inch. And has been many since.

The production big block (Mark IV) was first introduced in the '65 Corvette, rated at 425HP, and became available in other passenger cars in '66. The reason Chevy came out with the Mark IV was so that the Corvette could compete with the likes of the 406 Ford and 413 Chrysler line. The deal on that is that those small block Corvettes (327s) were gettin blown away by those the monster motors from Ford and Chrysler, and the Corvette types wanted Chevy to drop 409's into Corvettes. The Corvettes had a 55:45 front to rear end wieght ratios for handling. If had put that elephant (409) into one, front to rear wieght ration and handling would go right out the window. The current big block Chevy (Mark I 348's and 409's) wouldn't work.

In 62', Chevy released the Mark II 427 big block (never hit the production line), but ended up in Junior Johnson's NASCAR Chevy and blew everything off the track, until NASCAR pulled the plug on it (wasn't a production motor). But, if were take a look at that Mark II, would see that it looked very similar to today's Mark IV ('65 on), where intake manifold had heat passages under the plenum, etc.

Chevy had plans for the current big block Chevy (Mark IV), and when released in the '65 Vette, gave a 60:40 front to rear wieght ratio, which meant handling was still respectable, and would blow those Wedge Chryslers and Shotgun Fords away.

I'm older, fatter, and perhaps less wise today, and I drive Cummins Dodges, but when it comes to Chevy motors, I live and breath Smokey Yunick and Bill Jenkins.

Wanna build a screamer smallblock? Lets talk .030 over '70 400 with a welded up 350 crank in a Camaro - will flip you over the driver's seat into the trunk when dump the clutch and hammer the throttle.

Here's one: What one year since the Corvette was released in '53 that it did not exixt from then until now? In the current parts manuals, or if talk to the duds that currently work in the Chevy garages, will find it from '53 on, but if look through the old AC/Delco parts manuals from that time, was one year was a "Stingray" listed, but no Corvette, thanks to Ralph Nader's war on the Covair (hint).
