oof. wonder what kind of power they can make.

I get it. But I'll tell ya, when we were drag racing, we bored/stroked one to 434. Ran well

But the 540" rat that replaced it ran smooooooooth for being 906 hp. I'd go rat motor again before investing in what is basically a prototype with unknown issues

You can get 50+ HP from a highly modified 5 HP Briggs & Stratton too...for about 10 minutes anyway....

I think for longevity you need a lot of "block" to withstand the bottom end forces..not sure the small block will hold up long under such extremes..sometimes you need that ingot weight to hold everything together..

I like it, but calling it a small block is in name only. Don't look like there is anything designed by Ed Cole that hasn't been altered greatly. Kinda like calling the top fuel engines Chrysler hemis. Based on yea, but not anything close to the 426 that hit the streets.

Looks like it's a tall deck raised cam design. Probably isn't on a 4" bore spacing either. Can't be to get 600" out of it.

You can bolt up a stock chevy water pump to it, motor mounts are in the stock location, and the engine is less than 1/2" longer than a standard SBC, but beyond that I agree it has more in common with a BBC than anything else. Cam location and size, deck height, and bore space are all a lot closer to the BBC than SBC. Even the exhaust port architecture is BBC or LS style rather than SBC style. 4.6" bore space, raised cam, 10.0" deck. 600" is the number they're talking about, but in the article they say it is capable of 662" safely using a 4.500" bore.

Interesting, hell it's cool as fock...but unobtainium for most people.

Let's see 4.4 inch bore, 10 inch deck, 4.9 inch stroke-it's a small block in name only. Maybe I'm old-fashioned but I feel a small block, be it traditional SBC or LS, should be based on a family architecture and have a certain degree of interchangeability and compatibility. A one-off example with proprietary parts and unconventional setup just to say it "fits" in a small block space does not a small block make. It's interesting though-I just can't really see the point unless you only want to say that you have a 600 cube small block. It seems other routes would yield similar results with less hassle, money, and the need for unique parts.

It's definitely cool. But when a ton of stock and aftermarket big blocks are out there to get the type of size the question comes up to why? Why go through the work to make a big inch small block when there are proven ways to get there with a big block?
