Custom cam ? My friend and I have been talking about cams the last week and I've decided to do just a cam and then the heads this next winter but.... I have a 2000 z28 with QTP headers and 3.73 gears... my friend has a 2002 firehawk with heads and cam, but he wishes that he would have went bigger. So he suggested a 242/246 590/595 on a 112 with +4.. I just wanted to know what someone elses opinion was, and it is not my daily driver also...
One question I have will I have valve clearance?
thanks

What are you trying to do with your cam? Just arbitrarily picking durations isn't exactly the best method to pick a cam. Consider that similar durations are being used in the cam only record holder, a purpose built 3000 lb race car using 4.56 gears. I would be brutally honest with yourself about what you intend to do and see what others are using to accomplish the same goals.

Well the car will be used to cruise and take to the track, I estimate maybe about 3000 miles a year on it and that is at the very most... okay guys my first choice was the Texas speed cam that is 233/239 595/603 at a 112, but the XE-R lobes are kind of turning me off to get it
a set of patriot golds or any decent spring should last quite a while even on xer lobes.something like a t2 which is a 232/234 on xer lobes would be a decent cam i would run,or if you want to trade some tq for hp get something like an ms3.
do you have a hp goal or maybe a track goal...
but any of the mid 23x cams are great cams...and they all respond well to good heads.
if you really want good power...don't skimp on the heads. there can be a huge difference between budget and well built heads. that can easily make up for going with a slightly smaller cam

The altitude is what is going to hurt you. A 12.00 @ 113 at 4300 feet is basically an 11.00 @ 124 at sea level. Here's a mod list from the last 10 sec club entry:
1998 camaro Z28 A3 347/ Trex / FTRA/LS6/SLP lid/SLP MAF/bellows/ported -tb/ asp pulley/slp- headers/x-pipe-1 chambers/th350,4000 stall/BMR subframes/lca's/torque arm/ tuned/tnt 150 shot/3:23/ mt Drags/ 1.59 60' 10.94 best mph 125.89
Since it took a 150 shot to get there, I'm guessing that pass is at full weight.
I'm guessing that I'll have to backpedal a little on my previous statement. It probably will take a serious effort to reach your goal at your altitude.

I'd say start with your suspension. Its going to take enough power that you simply have to hook to even come reasonably close. Once you get the chassis sorted out, focus on getting your car to run good numbers with stock internals. Use your mph as a good indicator of the power you are producing to see where you'll have to be (how much more HP) to hit your target mph.
IMO, you are better off with excellent heads and a little less cam. Even if you are olny putting 3000 street miles a year on it, they'll be easier without a monster.
Also, if you haven't already, consider shedding some weight.
Good Luck!
