What's the biggest HP drain in a cam'd car?

The stock SS that I raced is known to be an absolute freak. I've seen it take down cam cars from a dig.
I'm gonna do springs first I guess. And I'll do a leak down test on it while I'm there. I've looked at brakes, flat tires, fuel pressure etc.
Idk about the whole O2 sensor thing... I'd think that they are either good or bad, no in between, but I'm not 100% on that so don't get mad at me.
I'll mess around with some small stuff and testing before I get too worried about it being something big.

It's happened to me; "Yeah I'm stock, just full exhaust and tune... me: ok lets race... him: wait what mods do you have me: just cam and full exhaust (back then) him: ok lets go" I get drug by like 3 cars... yeah... bullshit. I later found out he was spraying with one of those stealth kits.

I don't care how much of a "freak it is", a cam'd car should never get drug by a stock car... Especially with a cam like a MS3. Unless it wasn't installed right? Who installed it? A buddy of mine made 450 cam only with a MS3... check your tune, plugs/wires/exhaust leaks somewhere/02s/etc... something's not right. It's not the cam... Either that, or he's lying to you and spraying you...

And if your buddy made 450 on stock ls1 heads with no spray I find that pretty damn hard to believe, maybe he has ls6 heads and is not telling you? Either that, or that is a VERY giving dyno maybe...

He's been accused of spraying, but no one has found it. Plus, we were going 65-70mph and I only put it in 3rd. I could have squeezed in a second or 2 of 2nd gear to get my momentum up.
I had a small "exhaust leak" where my Y-pipe came back together, but it looked like a wheep hole to me. Idk if it's ok for a weep hole to be at the Y.
My PCV valve has a coat of oil on it, but last time I smoke tested the intake, it didn't leak any air.

I have drug several cam cars with my old mild bolt on car, it's called traction and not doing this ~~>

Tell him to pop the hood and take off the lid.

Lol. People have done it before, but no lines anywhere.
I'm not saying that a cam car couldn't beat a bolt on or that a bolt on should give a cam car a good race. But milage on a motor does bring down the power. They loose tolerances and aren't fresh. It'd be like saying that someone could run a marathon after spending a day doing yard work better than after a fresh night's sleep.

Granted, yes, with mileage these motors will deteriorate (like any motor) but 114K is not that many miles, like I said, IF well maintained.
I don't know what problems you may have with the car man, but the cam is not the problem, it's a proven cam...

No I'm not complaining about the cam. I love my MS3. I'm just saying there's something wrong with my car.
But who knows... Maybe it's just the adaptations from driving like a grandma from the bad clutch. I've been trying to over ride that by doing WOT, but shifting short.

I've seen guys drill holes in the back of blocks and put bulkhead fittings, and run fogger nozzles into the bottom of the intake ports. But yours probaby needs the tune looked at, and probably valve springs and an all around tuneup.
