Just for fun, "someone" overlayed my dyno chart with the chart from an LS7 from a leading LS shop. Thanks anyways, but I'll keep my little 403. Just goes to show how you can F'up better heads and a much better intake manifold. Not bashing here just sharing info. "Just the facts Ma'am, just the facts" (Jon may be the only other person here to get that reference)

Shows just how important a total combo is instead of just big ports and a big azz cam.

Yeah I wonder how big that cam is as well.... how else do you get a 427 to get spanked by a 402 unless someone totally dicked up that cam?

What head castings are on it? FAST 90mm I would assume.

As I understand it, this is an LS7 - LS7 heads and intake manifold.

Are you kidding me???? Jesus those things make 550rwhp falling off a log! Kieth's made that much running on 7 holes!

That explains the HP peak though.

C6 Z06. Ported heads/cam, ported intake, ported t-body.

In contrast, the brand new Z06 we built, started at 423, we ended up at 519 with 499 ft lbs, stock idle, and 425 ft lbs at 2 grand. With some miles on it, I would think it will end up close to 550.

There's a thread on here about it.
