Okay i need know some things. I know that a h/c swap on these cars does wonders. But i see alot of cam only cars around here makeing very close to 400 hp. with full bolt on. I also see alot of used cams on this site being sold for less 400 dollors, are they the good ones or what? i mean thats perrty cheap and a good hp gain, or am i missing sumthing here?
see this what i was thinking, do full bolton and get cam. Save for a bolt, build the engine a bit so it can handel a around 600 hp (never plan on makeing over 550) and then put on a 100-150 shot (more than liky a 100) and make very close to 500 hp with the 100 and lil over 500 if i go 150.
So what am i missing.

there's absolutely nothing wrong with used cams; i've bought two of them, an old mti T1 and a tr230. just follow the advice i laid out in the cam guide; ask for serial numbers and/or markings and a cam card if possible.
600hp at the crank is around 500rwhp through a t56. a cam and bolt on setup w/ the 100+ shot can hit that quite readily. 500hp at the crank is around 420rwhp through a t56. that can be reached with a fairly large cam and all the bolt ons.

Keep in mind that there is more invovled in a cam swap than the cam itself. Springs, pushrods, retainers, tune, install, possibly oil pump and timing chain.
You can easily get a brand new cam for $400.

You mean cam only versus heads and cam? Cam only, with full bolt ons, is a very economical level to modify your car to. How much it costs depends on what parts you get to go with it, who tunes it and who installs it.
Search and read the stickies, there is a ton of info available.
IMO it is very worthwhile to go cam only. I don't plan to touch my heads for a long time. I spent just over $1,000 for my cam, springs (withseats, seals, retainers), pushrods, timing chain, and oil pump. I installed it all myself in my gargage (mostly thanks to www.ls1howto.com) and had it dyno tuned by Speed Inc (usually runs about $450). Total cost to me, including a tool or two I didn't have but needed for the swap, was about $1,550.

Only doing a cam for now would be fine, and definately worth it. I would install it yourself. I installed a cam with my friend in his TA. It is hard, but it's great experience for you, helps you get to know your car better, and saves you some $$$.

Get a converter before putting a cam in. Do some research and get a converter with a stall speed that matches the powerband of the cam you intend to purchase. You will want to know what size cam and converter you want before buying either one.
Autos are much easier on the rear when launching than the manuals are. It should hold up.
The transmission, on the other hand, is something you will need to keep an eye.

Autos will eat a little more power than manuals, but in a drag race a properly setup auto will normally win. Stalled auto > manual at the strip.
