It already had American Racing 2" headers with catless X-pipe.

Exactly what I want but don't have an LS7. : (

Do you guys have a comparable package for the LS3 for my 1le?
Really looking at going with the small port LS7 heads and to be determined cam.

Yes we have a package we use on the LS3 stuff also.

Nice. What are the cam specs?

I think this might be the most powerful naturally aspirated Gen5 Z/28 done so far.. unless anyone knows of one with better numbers?

Well done regardless!! ��

Spoiler alert!

I had this video queued up on my Youtube to watch later.... now, no point.

What the package cost?

Its our B3 cam. You get specs with the cam card once cam is purchased

Stirring up an old topic here, but curious how drivability was after these upgrades; especially low RPM street driving (and stuck in traffic scenarios).
My Z is already upgraded, but toying with the idea of tacking a bit more onto her now that I have most of the parts to take it back to stock when I want. One downside to doing that though is core exchange; I have heads redone by LPE on the car right now, and I have a set of brand new in the box LS7 heads that have never been bolted on. Hate to get only 1500 back for the core charge on either of those :/ (would returning the LPE done heads as a core even be an option).

Just curious, didn't you just mention that you have yet to enjoy your current set-up at wide open throttle? Maybe take your ride out and run up to 7 grand a few times before you spend a big chunk o' cheese and turn your car into a cantankerous street machine that may be more at home on a road race course as opposed to a trip to the bank or dry cleaner. A car buddy of mine just sold his 630 HP (crank) Z and remarked to me that after the major mods the street driveability suffered. It sure was a beast on the track however.

This one I haven't really opened up. My last one ('15 #619) had a bit more power to it (but tbh I didn't open that one up that much either), so I'm familiar with what my current one can do where its at (+25-30whp). Right now I'm just tinkering with the idea; still gathering the last of the stock parts, so it'd be a few months down the road regardless. I'm one of the, probably few, people that will add power and not actually beat the crap out of their car lol (and I am highly unlikely to ever take it to an actual track).
Street drivability is why I asked the question though; I spend a lot of time at lower rpm (say 1700-2100rpm), so thats a must for me :)

Leave it as close to stock as you can mentally tolerate. When you install a more aggressive cam your power band will move up accordingly. Low speed driveability will suffer along with your wallet. I know I'm telling you what you already know but maybe you just need to be reminded.
