Which Cam should I get?
Well, headers are shipping out on the 30th and I am thinking shortly thereafter it will be time for a CAM!!! I am debating between 3 fairly different cams. The GM847, cc306, and XE230/236. For the time being it will be on stock heads, but as soon as I can afford otherwise it wont be. My car Idles at 1000 RPMs as it is so hopefully idle wont be a problem. Basically, which cam should I get and what fuel upgrades should I do along with it? Also, what are people making with these on stock heads. I thought I saw a guy on here pulling 380 with the 847 on stock heads, but I am trying to find it now and can't. I'll keep looking.
Thanks Guys

When I get around to doing my cam swap I'm either going with the cc305 or xe 224/230. I'll be on stock heads for a while, but hope to eventually have them ported by Lloyd. Both these cams seem to be favorites for daily driving

I decided to go with the CC306. I made 354 rwhp and 352rwtq with the following.
stock heads
stock TB
stock intake
jethot longtubes
true 3" dual exhaust
moroso cold air
1.6 rockers
ASP underdrive crank pulley
CSI Electric H20 Pump
and LT1 Edit.
This was with 108,000 miles on my stock short block.

Those are pretty large cams. Do you want this for the street? If so, I would shy away fro mall 3 of your choices.
I would look at something like the XE 224/230, the CC 305, or the hotcam kit. The XE224/230 is great for stock heads.
When you go large like your 3 choices, the powerband is very high in the RPM band and you need to rev high.
When I get a cam, I want it to peak between 5700-5900 rpms, so I can keep good torque down low and I don't have to rev the crap out of my engine. That's me though, you may want a different type of cam.

Now here's the thing, when I first turn the car on and drove it after the cam swap, it was not streetable, but after I made some adjustments with LT1 Edit, it is extremely streetable.

If you do not have 1.6 rockers yet, the LT4 Hotcam Kit is a lower cost alternative since it comes with the aluminum rockers and valve springs.
When you go large like your 3 choices, the powerband is very high in the RPM band and you need to rev high.
Regardless of which cam you pick you, you will be pleased, personally I think the LT4 Hotcam would be a good "starter" cam for you.

Ahhhh, if it were me, I would go with the gm847 cam. That cam makes awesome power in our cars and is just bad a$$. That is what is goin in my car this winter, with a set of lloyd elliot ported heads. Hoping for 400+ rwhp.

I'm for the GM847 too. A couple of guys on here have had success with this cam on the street with stock heads. With ported heads and the GM847 cam my car drives no different than when I had stock heads and a small cam.

I don't have the numbers for the gm847, but I know the lift is .575/.595 w/1.6 rr's. The duration is pretty big too. But the cam makes awesome power. I'm sure someone knows the rest of the numbers off the top of their head. But it is bigger than the cc306. Like you said, why go small, when you know your going to want bigger. I learned/ am learning that first hand.
