comp cam question?
What he said. It COMPLETELY depends on your goals for the car.
I prefer a cam with a broad powerband that hits hard in the low/midrange as opposed to a large cam that sacrifices below 3500ish rpm but pulls harder on top.
Were it a drag car though, that bigger cam could be faster at the track, depending on the gearing and total setup.
I'm a big fan of the comp XFI lobes. They are very versatile in that you can keep durations low, but have a respectable lift #.
They do require a well thought out and set up valvetrain though. As should be the case with any cam you choose.

I had one in my blown 383 with stock ported heads & 1.6 rockers. Made over 650rwhp with a D1 Procharger. Went 10.0 in a full weight Camaro.
This cam is good for a daily driver with a reasonable idle & will actually drive along in 6th gear at 1000rpm when tuned properly.
I have a used one for sale (in near perfect condition) if interested....
plus new 1.6 Crane Golds, 7/16" studs, new guideplates etc.

There are much better lobes available in modern grinds.
Have you considered something like a a CC503 (224/230 112LSA) ?

I know it gets a bad rap but I just installed a CC305 in my fresh build. With ported heads and 1.6 rockers the cam has a little bit of lope (only enough to know its got a cam in it) but idles nearly stock and pulls like stink off idle. I can put it in 6th gear at 1200 rpm. I'm happy with the choice. I really don't think an extra 10 or 15hp is worth changing the car from something that drives like a nearly stock car (except having a ton more power) to something that feels like a race car.

The cc305 would be a tiny cam in a stroker. It's an older grind but over the years it has worked decently well for people running stock heads and bolt-ons, seems to work decent for people running power adders too. If it were me I would go with the cc503 which will act very similar but make more hp/tq throughout and have a more choppy idle (if that's what you want). Bascially it simply comes down to what your looking for from the cam in determining whether it's a good choice or not.
I just pulled this cam from my 383 earlier this year for a custom grind from Lloyd. As stated the CC305 is a good cam but pretty old school as this was the only (emissions friendly) cam available when I built my stroker back in 98. If you are looking for a good power spectrum and to stroke the motor I would highly recc going with a custom grind spec'd out by Lloyd. If you are leaving your motor stock (heads/displacement) then this is a pretty good cam and it's a bit more powerful then the LT4 Hotcam and also is emissions friendly. Let us know your goals and that will help better determine the cam you need/want.
Honestly I went with the CC305 simply becuase I wanted to keep a very near stock idle because I run the car in autocross and didn't want a very noticable idle. I went with bigger valves and ported heads in order to get air into the cylinders while still having a very flat torque curve and responsiveness. Like everyone says, it TOTALLY depends on what you are trying to do with the car. That being said, if you mistakenly chose a smaller cam you are likely going to like driving it more than if you make a mistake and pick a cam that is too big and don't have the supporting mods.
