Scanning through the text in the link before I clicked, I was like "meh" when I saw "1200 hp...twin turbo LS...". Then I put it all together and popped a chubby.

Just saw the video the other day, pretty incredible if you ask me.
Granted its a prototype but, I'd love to know the breakdown of components used for that build. Talk about stout.

cool article, curious how they got down to 260 cubic inches?

EDIT: Found the answer on their FB page...

Nelson Racing Engines: 3.890 bore 2.725 stroke

so it looks like a 4.8/5.3 block bored out to 3.890 with aftermarket crank with 2.725 stroke

I need to loop this sound so I can listen to it at night while falling asleep instead of my rain storm app.

that is amazing, to perceive what the lifters/rockers/cam or cams? and plain bearing crank/rods are enduring im in disbelief? say goodby to big blocks?
