The Small Block Chevy V8's obituary from the 1980's is still premature. Remember when the "experts" said the V8 was toast? Well, butter it up.
As emissions and mileage parameters continue to tighten, the Pushrod OHV V8 is still a world class engine, in cost, weight, power, and efficiency.
For 2014, it's 372 ci Naturally Aspirated version will push 450 HP and 450 FTLB on pump gas while achieving tight emissions and 26 mpg.
And that's 450 modern SAE ponies. Or about 560HP gross from the 1960's pasture.

Chevy shaved even more weight from it's mouse motor for 2014. But it's still a V8 pushrod 2v mill.

Thanks, I think. :?

Dan,
I bet many other engines make more HP per CI...tell JW we said hello.

Jeez, tough crowd. :-D
Yes, it doesn't hold any HP records. Although Chevy does tend to understate HP.
What it does, it proves "old school" engine design is alive and well for production engines. This bolts up to a 2012 minitruck (drop in) or even a FWD sedan. Obviously, since they (family) are already in there from the factory. These are engines that routinely go over 200,000 miles.
For a V8 it's small and light and mainly CHEAP. 450HP is with the emissions and accessories, programmed for pump gas. Figure in a few hours and some skill, you'd increase about 15% based on the other models.
No, it's not useful for LSR, hence the NON LSR Posting. It is useful for street and dirt purposes. And like the other SBC's you'll probably be able to buy it in crate format.
The LS1 is now about the most common engine swap done to older cars and sand toys. It was 345HP at first, now it's higher. And yes, the LS7? goes 505HP NA, but it's fairly pricey, since it is dry sump, titanium rods, and ported heads.

"...routinely go over 200,000 miles."
if it was 200,000 MPH you may find more interest on this board. Don't need that extended milage, just a measly 10 miles.

Correct. To an extent.
Sportsman type racing always has budget constraints.
There is a reason folk put these engines in older hotrods and sand rails instead of 2.02 iron camelbackhead 4 bolts. The amount of money it costs to bring a 1970 SBC to 2012 SBC levels is quite a bit more than a crate LSx engine. Roller cam? Included. Large port aluminum heads? Included. 6-bolt mains? Included. Nitrated steel crank? Included. High flow manifold? Included. Super 8-coil ignition system? Included. Datalogging? Included. Etc.
Since these engines (LS family) can be found anywhere in US for under $2500 in excellent condition, perhaps they are not as pointless as you might think.
How high can you turn them up? Past 1000 is very old news. 750hp ten years ago NA. Sounds too low to be useful? 750HP was breathing through two 31.8mm restrictors, that's about a single 1.750" hole?
But again, this Off Topic and not related LSR, just a piece of history. Not all history is from the thirties. Some of it occurs daily ...

Think of it this way.
Why do folk run NASCAR engines or Busa engines?
It's all their budget allows. Neither are the most powerful per CI out there.
But perhaps some have even lower budgets?
