I'd like to hear the specs on the cam. To produce that kind of power you would need a fairly high lift, long duration cam. To say that a high lift cam can be used with stock heads would need to imply that these heads flow fantastically out of the box. I do not know of such heads. 440 + rwhp, even with open headers is 500 + at the flywheel. Not claiming :skep: , but it does seem odd .
It lopes really hard and the tachometer displays 900rpms as it did new. If it sits for a while it sometimes drops down and then quickly picks back up. "rarely"
I am going to try and post a clip with it idleing this evening.
I have only taken it out a few times with the new mods and every time some one coments on how bad ..s it sounds.
One thing I am trying to get use to is when I am in 1st gear idleing/rolling the car surges/jumps with the cam.
I ordered this car 2002 on July 25, 2001 and pulled the car off of the truck at Ray Huffines in Plano October 12, 2001. 1.26 miles on it. I dynoed it when I had 3k miles on it and it made 360hp which was higher than 6 other 02 z06 that same day. I do not know, may be I broke my car in properly or it has less flaws in production. ??? My friends still can not believe how much power it made with out heads. In fact everyone is wanting me to put heads on to see how much power it will yield.

All cars (even with the exact same engine specs) are a bit different. Mine dyno'd at 350rwhp with 800 miles and 1100 miles. I've had mine a year and only 5100 miles. That may be a problem...I need to beat on it more.
I have built several hot-rod motors and every engine builder I talk to says to beat on it after 40-50 miles is all. With the new technology in ring design, etc, everything "seats" within minutes of firing the motor up the first time.
But GM says to baby the thing for 500 miles, so that's what most of us do. I would like to test that theory, but not with my $44k that I paid. ;)
Anyway, the fact is that you got one that makes more power than most from the get-go. It's at 438rwhp or whatever now. Enjoy it. It's seriously fast. :D If you need more, throw a mild 100hp shot of nitrous on it. You will not blow anything up if you stay conservative with it.
What's most impressive to me about that graph that BHaggard posted is that they are not spinning the motor to oblivion. Looks like peak HP is at 6400-6500rpm...but it also looks like its climbing, too. Still, its nice to see it doesn't take 6800+rpm to make the power like some of these set ups are. We're getting into the solid lifter realm at those types of rpms.
Congrats on your car!
Amazing, about 15-20 RWHP higher than the cars we do with similar mods.
Is that without removing the catalytic converters?
If you ever want to get another dyno reading for comparison,
I would be glad to let you to do some FREE dyno pulls on our dyno.

We average 440 rrwhp on our stage 2 set up in mild tuned form all for under 4000 installed.When we add headers,pulley,stingers Dyno tune and a slightly more aggresive cam price goes up by about 1k and we see another 345 rrwhp.
Again for your best prices on packages,parts etc... we wont be undersold.Look for us on the April/May cover of Vette Fever,we will show case 3 cars over a 3 month periodand with our full service shop can outdo the competition and whoop them on price,Dave S. 480-517-4969
:rolleyes: :confused: :crazy: Gee Dave, this post is about giving props to an awesome car pulling some impressive numbers, it's not about you! Also, did ya know there is a period and space key on your keyboard!!! :rolleyes: :confused: :crazy:
Just curious. Do you have specs on the cam? If you can't post them (because they are not for public consumption) can you give some general details such as 59x. or .60x lift or at least the LSA of the cam to give us an idea of how this cam would idle...
Thanks...
BTW good numbers. Sound like number similar to TAMUz06
yes, i'd be very interested to hear the cam specs as well.
Sounds like you picked up some awesome power. I'm assuming, it was a wild enough cam to necessitate dual springs?? So the heads did come of for this process?
are you running cats for the street or is it strictly off-road setup?
