Nice numbers!
I dont have any way of recording it, but it sounds exactly the same as a stock with a louder exhaust.

I'm not one to really speculate, but if I had to guess it was gonna be in the high 11.5 range. If I had something other than the stock gear, it'd be a smidge quicker, maybe bottom .40's or so.

We have a big block MCSS we run at the track with no belt because it throws belts all the time. EWP.

It gets from the trailer, to the staging lanes, down the track, back to the trailer, all under its own power, no alt. Just charge it between passes.

Not impossible at all.

OK, these are great and realistic numbers. Yes, TQ is always higher than HP on a stock cam (except maybe the LS6 cams). That is what these cams are designed for. Keep in mind this is the Vette cam, not the F-Body cam. So more lift and durration. Also, the coment about the VE not changing with the rockers...WTH are you talking about??? Anytime you add air to the motor the VE is different. Heads, rockers and even intake will change the VE.

This car is not going to run anywhere near 11.5Xs. Way too heavy for the power and gear. It will be lucky to break 11s but should trap nice. I would guess 115 which with a stick is only good for 11.9X-11.8X tops. And all this is great for a stock cam car. Good luck and can't wait to see results.

I would love to see numbers with 02+LS6 cam and ported 90/90.

Just so you know, the '04 GTO cam IS the same as the '01-'02 F-Body cam.

Cam Doctor verified it years ago.

i don't know why people insist on saying people aren't truthful. This person posted up 4 different dyno's to show you. He explained everything, and still some people are skeptical. I don't understand why though. Even if the dyno read high, better for him for his bragging rights. I don't think he is even bragging either, i think he is just as amazed as we are. Don't be mad cause your head/small cam car is making less power then his, cause **** happens.
Enjoy the power, and don't care if people don't believe you.

I literally lol'ed....

this thread makes me tempted to thwrow my 98 cam which does have more lift and duration than the 04 into my new engine....nice results...gotta love all the haters on here....

I also lol'ed on the 1.85s increasing duration....some people have no clue

Default 1.85

I went to SLP and with there 1.85 01-02 cams go to 505 lift and the older cams go to 550 lift.

they do, technically, by how the engine sees it. the seat to seat duration would remain the same since zero times anything is zero but the .050" duration the engine sees would grow slightly.

at first I was skeptical of the graphs. you have a lot of info backing you up, now you just need track times and it would be complete.

That is news to me.Then where does the extra power come from as they are rated at 350? Unless the F-bidies were greatly under rated and the laws changed for the Goat or something. But everything else I mentioned remains the same. And that would further prove the higher torque numbers than HP since those cams typically had a better TQ/HP ratio than the vette cams.

The GTO just got a truer rating compared the F-Body. Its the same engine. Only difference was exhaust manifolds and oil pump/pan. Later '04's got a different water pump and head bolts.

a 1.85 rocker WILL slightly increase the duration over a 1.7 rocker,as was posted above..think about what actually happens in a valvetrain before you start insulting someone..

look at any cam card...any...most show lift in different ratios 1.5/1.6/1.7 blah blah blah....the duration stays the same...not like the rockers magicaly changew the lobe design....the ratio is increased and....boom you get more lift.,...

I'm guessing he is talking about it at the valve not the lobe.

mine doesn't show different ratios,just the 1.7..and i'm only talking about a degree or two difference..if you don't believe me,ask one of the experts on here...

Yes, at 0.050 lift (typical standard cam durration rating) the durration will be different with a higher ratio rocker since you will reach 0.050 lift sooner and drop below later.

all im getting at is he didnt gain enough from what little time the valve is open longer to matter...the higher lift yeah but not from maybe 1 degree of duration...

the way you guys put it it looked like you were saying he gained... .15 % in duration as well as lift...

I hate trying to relay things over the net...

to the op nice #s sorry for jacking up your thread...
