I wish we could hear its true exhaust note.

So it basically makes 600lb/ft from 4000rpm to 6000rpm. with a fairly mild cam.

Wonder how much it makes off idle. Probably close to 500lbft.

Wonder if they used a lot of the 4.3L LS. Wouldn't be surprised if the exhaust manifolds were from a couple of them. It seems to be a bunch of fairly stock parts and using traditional LS parts 600+ CI would likely be plausible without a ton of work if they went to a large bore style block.

Doesn't sound much different than a V-8. Looks like a truck exhaust. Get some tubular beauts on that thing and let's hear it scream.

Yea and to think there's enough damaged LS7 blocks and heads out there. Find two sets of those to cut up and mate together at you'd be pushing 700 cubes!
