You can thank edelbrock, Offenhauser and a few others. The original small block wasn't a bad critter... the 283 had great rod/stroke ratio, good bore/stroke ratio and didn't take up much room. In as much as edelbrock claims to be the first to reach 1hp/cid, it was actually Desoto...
What made the engines was in fact, the commonality of parts. What destroyed it was the lightening of the heads, iron shafts, over boring, over stroking and siamese cylinders all being supported by what was then, an incredibly poor way to siamese the exhaust valves in the center of the head... this feature should have been dropped upon inception of the 327. Bottom line is there was too much heat build up in one area! They made a pretty decent medicore life marine engine too... LH or RH engines... cheap to cast, machine, manufacture, assemble and out the door!
Unfortunately, and no doubt a cost cutting measure GM hung onto it too long... the engine since, has been in the way of technology left on the side of the road passed by every manufacturer's offering... I'll always wonder why GM spent horrid amounts of cash to develop a new series of V-8 only to shelve it in favor of what they have... all the work, foundry, dies, patters, etc were all tried, proven and done!
I suppose, for what ever purpose Opal technology is in every four banger, the modular 4 and 5 cylinder appear to be faithful, the big blocks are worthless and the duramax can go no further in hp. Come to think of it, GM shelved the mini duramax for half ton pickups too!
The times, they are a changing!
