ls6 compared to gm hot cam how is the hot cam compared to the ls6 cam? which will produce more power? i know the hot cam will make lots of low end torque which is what i want 
, i dont know about the ls6 though?!? everybodies opinion is wanted. thanks

i'd go hot cam over the ls6 cam. the hot cam has more down low and mid range compared to the ls6's top end. both are pretty mild cams.
i'd shoot straight to a 220, 224 grind myself

the thing is, i am putting a ls1 in my 68 firebird, but i dont want to put the motor in stock, so i am just looking for something until i can actually build the motor later. for now i am just gonna get a cam, ls6 intake, headers, and maybe a tb or maf, and a 3000 stall. it is mainly going to be a street car, but i will take it out to the track!! so what would you recommend for a person wanting to make about 375 rwhp? thanks

Hotcam makes good torque, and sounds great.

LS6 cam in an auto car is plug and play. You will have to have tuning to run a hot cam with an auto. Just something to consider. Although, putting a LS1 in a 68 is going to require cutting the sub frame and boxing in the cuts, so something like a little tuning might be a minor issue.

I have no track times yet. I don't have the ***** (actually I have no friggin' money) to ruin my stock 10bolt yet. I have some real traction issues with my stock tires and 4.10s, but it is fun as hell for the street. If it's any indicatrion, I can tell you I have raced ZO6s, SC cobras, etc on the street and walked them all. All my mods are listed below. It pulls hard in the midrange which is what I planned for.
When the 12bolt comes, the fun will really begin!

thats impressive, i just want the car to be a lil more badass than stock, that is why i'm curious about the hotcam. i plan on building the motor better and stronger later on, but for now, just want to beable to drive it lol. ohh i just found out that i wont beable to put lt's on the motor, the power steering is in the way, so do yall know what difference in power is between lt's and shorties. i know i should post this in the other section, but while i have all of yalls attention i thought i would go ahead and ask. and one more quick question, where did you get the car tuned at, did you bring the car to somebody or did you just pull out the ecu? thanks

I tuned the car myself with LS1Edit.
I believe some people say GM's Hotcam is OK with more restrictive exhaust (ie, shorties, stock manifolds), because it has longer exhaust duration. I'm not sure how true that is, I'm sure less restrictive exhaust is always better, but it does seem ideal for you right now.

Just be aware that there appear to be some alternate solutions just around the corner (check the PCM/Tuning forums).
I'm still running the hotcam with stock heads and LT's in my M6 without much beyond a MAFT in the way of tuning. I realize that with an auto you will need more work, but I think this would be a great "old school"-sounding cam with very little worry until you upgrade to something better. Its a cheap setup, makes pretty good power, and is very reliable.

As far as tuning goes, it all depends on how "perfect" you want the tune. If you just want it to idle of, then it is almost trivial using idle. Most people change their VE setting a bit, a little more timing near idle, etc...
But if you want to squeeze the max amount of power out of your setup, you need to use a dyno with a wideband, and fine tune the A/F mixture across the entire RPM range.
There are lots of great documents floating around on this site and others that explain the specifics of what computer setting to modify.
The first topic on this forum is great for idle tuning issues:

Good luck!
