Looks to be about inbetween the ZZP GT2 and GT3 NA cams. Pretty agressive unless you really do some internal work.

Comp Cam on Ebay: .512 lift, 115-degree lobe separation angle, 210 degrees of intake duration and 220 degrees of exhaust duration

Intense Stage 1X: duration @ .050": 212º/216º, lobe lifts: .327"/.321", valve lifts with 1.60:1 rocker arms: .523"/.514", lobe separation angle: 113º, intake centerline: 109º

So how do these compare? Looks like the Comp Cam has fewer degrees of intake and more degrees of exhaust, but what does this tell me? The valves are open longer?
I've read once that most cam stats use 1.5 ratio rockers. If this is true the comp cams one using 1.60 rockers would be .546 while the intense one using 1.5'* would be .490 . Dunno for sure though

So Jay, what would this mean in a normally aspirated application? I had my buddy from the TCCOA research the cam a little, and he said it seems to be a blower cam. He thinks I'll definitely see gains from it, but I'll need new valvesprings for sure, maybe retainers too. It'* really tempting. If it gets down to the last day and is still sitting at $100, do you think I should grab it? I don't want to get something that won't really compliment my car, even if it is cheap as dirt. I need some honest, plain-English advice about this deal. I really appreciate all you guys' help.

I'm not sure about it being a blower cam but the lift and duration is pretty big. You'll surely need springs, and nice to get retainers.

The issue is a cam is the heart of the engine. You want to build your engine around it. As stock your intake manifold and exhaust are generally setup for the lower end of the middle range. This cam is set for the upper end of the upper end haha.

Honestly I'd only get something this large if you have or plan on quicky getting headers and porting done. That'll take the rest of the engine to the upper end to play along with the cam. No doubt you'll get gains as-is, but you'll be shafting yourself out of HP and it'll probably suffer/run nasty in the upper end. Think of it like having 15lb lungs but breathing through a straw.

-----------------

Interesting to note that Intense contradicts itself reguarding its cam.

"The new Stage 1X Cam is the IDEAL aftermarket cam for use with stock heads, lifters, rocker arms, springs, retainers, and pushrods."

So I can stay stock? Scroll down:

-We recommend that a new timing chain and timing chain tensioner be installed in conjunction with any new 3800 cam

-We recommend CompCams "OE R Series" Hydraulic Roller Lifters, High Load Valvesprings, and Valvespring Retainers with any aftermarket camshaft

-We recommend INTENSE™ High-Performance Pushrods with any aftermarket camshaft

-No PCM changes are required, however the INTENSE™ Stage 1X Normally Aspirated Cam may set an occasional *.E.*. light after extended idle periods

-Higher WOT shift points (6,300 to 6,600 RPM) and rev limiter settings will further increase the performance of the Stage 1X Cam

Oh wait...guess not.

Well, if you go by the specs in the description instead of the sticker on the box, it looks like the 3800 Performance L67 Cam to me... That cam actually performs pretty well, but I tend to believe the box more...

Thanks for all that input, guys. I talked it over with my buddy and we decided it would be better to hold off on a cam. If I get anything it should be something that is designed more specifically for a normally-aspirated application. This cam is nearly identical to Intense'* blower cam, meaning it won't benefit my car like a Stage 1X cam would. Plus, like Jay said, I would definitely have to sink some money into my valvetrain right from the get-go. I'm in college and I'm getting married in six months, so I think you will all agree that I have more pressing financial concerns.

The other issue is the weak driveline in L36 cars. My transmission already has over 110k miles on it, and we're thinking I should definitely get a different torque converter before giving the motor more power. Maybe even a limited slip. It'* just that I'd really be shooting myself in the foot if I spent money upgrading my motor and then blew up the tranny. I just don't have the money to take those risks. I know other guys have cammed their L36s without trouble, which is why it'* so tempting! But I think my only realistic option is to put it on the back burner for now.
