So, I bought a 2002 Z28 6-speed a while back. I've had many F-bodies in the past and have never had the opportunity to have a cam installed. I finally got the opportunity (had the money) to get one installed and I was very impressed with the results.
Let me start with a little background on the car. It had a full exhaust on it when I bought it (long tubes, catless Y and slip catback) It had supposedly been dynoed by the previous owner by speed inc. and put down around 345-350 rwhp. I called a local speed shop here in central Illinois by the name of Scram Speed and talked with them about my goals and if the car was a daily driver and so forth. We decided on the Brian Tooley Racing Stage 2 cam. They said it would be a cam that the LS1 would really respond to while still keeping good street manners. They had my car in and done within a week of
when I called and at a very reasonable price, in my opinion.
I was expecting to see around 400rwhp, tops. After the cam install and dyno tune, it put down 430rwhp, so I gained around 80whp from the cam and tune. I was pleasantly surprised and I love the way the car feels and drives. It definitely gained a noticeable amount of power while retaining the street manners of a stock LS1.
I would recommend Scram Speed to anyone. It's nice having a shop like that 15 minutes away from home, rather than having to drive 2 hours North to the Chicago area. Here is the dyno graph.

You do realize you didn't gain anywhere near 90 hp right lol?

That's what I call RESULTS! How is the idle? Much lope?

HCI, my bad. You're right. I should've put 70-80rwhp.

G astma - the idle is relatively smooth, but it definitely has enough of a lope to tell that the car is cammed. I'll try to post an idle video soon.

Thanks man! Sounds like a fun ride!

I have had some un explainable cam swap gains my self lol. I had a 04 bolt on gto that made 340whp. Added a cam and a cat back, took it back to the same dyno. 428whp. 88hp... Catback might have been worth 5-7whp I would think?

Yeah ive seen things like this too and on paper it can be hard to explain, but there could be several reasons. Even reasons that most people would never think of. I've also seen where someone gains like 30 hp from a huge cam on the same dyno. That's why I always say take to the track and see what it traps, as that will be the true indicator of the power gained

OP, I wasn't trying to sound rude or anything, I just wanted you to understand that a cam swap alone wasn't going to make that kind of power

Nice results... Unfortunately, you don't know how much you gained unless you redyno at speedinc.

Isn't that graph showing calculated engine power and torque as well? Not rear wheel?

yeah, if just only change was the cam to a 227/234 on a dynojet like it was dynoed on at speed inc it will prolly be less than 400 rw. still a great cam though.
