But since everybody wanted to see a dyno sheet right away, I decided to post a realistic dyno sheet of my car in it's every-day setup. Remember, my car is my cross-country daily driver. For me, it's ideal.

Since it will probably remain a daily driver here, have you even contemplated which exhaust system you'll be going with yet? Mufflex 4"? Bassani true dual? Again, just wanted to congratulate you... those are some very impressive numbers for a daily driver, w/zero hassle!

Last I checked almost every F body owner drag racers their cars.

Maybe you didn't notice my sig and the cam I run. Trust me I wasn't puting down any cam just throwing some light on the subject.

Off the top of my head, various forms of open road racing, road racing at tracks, One Lap of America, autocross, and drifting (

) You must know a helluva lot of F-body owners, I wish we could get a decent car show together

Sorry, I just feel there are too many camels in the proverbial sandstorm. It wasn't intended to be personal

2 degrees more overlap makes for poorer idle. In this case 110LSA cam idles smoother than a 114LSA cam. Make sense?

You're right, my bad. I've got alot of learning to do. This is a great thread by the way guys. Keep it up, I think alot of people are getting some good ideas here. Thanks.

Yes and in every one of those style of races except drifting the rpm's stay high. Even in autocross when you come out of a turn at 20MHP your in 1st gear and need RPM's to advoid having another car pass you. Which means your always above 4000 and mostly always above 5000 RPM's.
By the way I run a shop that works on F bodys everyday its my job and the way I feed myself to know F body owners.
I can even give you address's, mods, and dyno sheets for each one.

Patrick did you ever solve the valve float you were seeing above 6400 with this new cam? Thanks, Ive never heard you answer this question....

I don't believe that's valve float. I believe it was dyno related. I have many other dyno sheets from other dynos where the LSK lobes gave perfectly smooth dyno curves. Same heads, same springs. Only on MTI's dyno did I get that crazy choppy curve. Typically, valve float will drop your power off very fast. Not the case with my sheets.

Not for a while. I've not even super-tuned this cam yet. I need to get a wide-band O2 sensor and get back on the dyno. I also need to install the better exhaust later this summer (hurry LGM). My numbers will climb quite a bit before I'm done with this cam.

Next phase down the road will probably be forced induction with large chamber heads to reduce compression. At that point, I'll probably go back to something like the CheaTR cam.

For now, it's all torque from this beefy cam and a healthy shot of nitrous.

Patrick or anybody with this cam,

Do you or anyone have a clip of the car with this cam so that we can hear the idle?
