getting cold feet... I'm a cam selection and pushrods away from having everything needed to do my H/C/I swap (AFR 205's, FAST 90/90, meiling oil pump, LS7 lifters, LS2 timing chain, gasket and bolt kit, LS7 clutch kit, new slave, and probably some other little stuff I forgot). I already installed konis on all 4 corners, strano bars, ARH LT's, lid, and exhaust and the car is running great. I have a bad feeling that If I go through with this its going to screw up the driveability of the car and turn it from a fun car to a pain in the ***. I dont owe anything on the car and paid cash for all the parts, but I do drive it every other week to work. This really isnt about what cam to put in it, but whether or not I should go through with the H/C/I swap.

my car is pretty close to what you have discribed, parts wise, H/C/I. stage IV spec clutch, and the car can be a dd if gas was not so bad. I have a 229/231 cam and 205 heads. Hell my 105 lb asian wife can drive the car like its a DD.

Do it with a decent cam, like mentioned above if you go small you will regret it, might as well only do it once. Take the cam you were looking at and consider the next one up...

Dude u already have all the pieces to make the Mamo setup work (I would have Tony Mamo port the FAST though if you want all u can get out of it). Go with the Mamo cam (224/228 cam from AFR) - it's not heuge and has made amazing numbers on a lot of cars. Look it up - pleanty of guys running just that combo (205s, FAST 90, Mamo cam) - it's not rediculously large but it's done surprisingly well again and again.

what are your power goals with the car?
m6 or a4?
where would you like your powerband?
final drive ratio? (gears)
full weight?
any future plans of forced induction/nitrous?
fill me in on that info and i can spec you out a cam that will fulfill your needs...

the car is a m6, 3.42 gears until the 10 bolt goes, full weight (hard top z28). I dont want to spin the crap out of it, probably 62-6500 max rpm. Basically as long as I can smoke my bosses A4 drop top C5, I'll be happy. Honestly reliability is what I'm worried about. The car hasnt given me any problems and doesnt leak a drop of anything right now. I dont want to turn it into a money pit of issues with the swap. Ive got about 9k into it right now, including all the mods on it and the parts sitting in the garage and price of the car.

yeah, its just that stock cars go to 100k miles easily, yet you dont hear of H/C cars making it that many miles without issues (blown head gaskets, spring failure). I guess I'll find out.

228r TSP, This cam is extremely streetable and makes awesome power.
I made 450/440 w/ that exact setup on a conservative tune. The car weighed 3700 w/me in it and ran 7.5x in the 1/8th w/ a 1.65 60.

I really think if you're trigger shy, you should avoid a gun.
Saying that, I think with the weapon and ability you have available, you should lay down the pea shooter, and go with the upgrade to the full auto.
I think with your proposed set-up, going with the 10 round clip would be a miscarriage of justice and would make my banana clip shrink to a jalapeno clip.

Ummm...I think I agree with Bry 
You have the parts for an awesome setup! I would use what you have, get a decent cam (low 230s or high 220s or even the mamo cam) and put it together. Get it tuned right by CMS and it will be very drivable. You dont need to worry about drivability until you step up to a big cam like an MS4 and even that can be very drivable with the right tune.
Not sure if you are planning on doing the swap yourself but having just done it I can tell you that it is cake. I took my time, ran into a couple problems and still had it done in great time. If you have any questions now or during the process let me know and I will do whatever I can to help.

With stock gears dont go over a 230, yea you can get a trex cam put it in but will it be optimal nope. Smaller cam will give you a nice tq curve and more usable power. Sure you can get a 230+ gear and to get the most out of it throw in 4.10s etc but then your right were you dont want to be. Do searches you can find many videos of small cam set ups hading a huge cammed car its ***. I personally would do a vengence vrx3
Smaller cams dumdumdum

anything over a 230 duration and 600 lift is a pretty big cam. I would get a motor built and drive it around breaking it in with no tune. Thats just looking for something to go wrong

Well I got the LS1 intake off easily enough last night, waiting on a couple parts (coolant lines and TB gasket) to put the FAST 90/90 in. On that note I dont see how people break the oil pressure sensor. Seemed like you would have to drag the intake across the heads to hit it.

^^^Happens when your lifting the front of the intake to slide it out typically. If you get the front up too high and pull it out, you risk damage to the OPS.
About your cam dilemna, I wouldn't be too worried about reliability and longevity, as long as it's done right. Like most have mentioned, no need to go with a huge cam for your needs. Get something around the 224-228 range, and you should be very happy. It's all in the tune. I have a 222/224 (wish I went a touch bigger, 228...) and other mods, and the car pulls very hard, but is still extremely driveable in all kinds of traffic. I daily drive my car and other than some fuel pump issues (even after the 255 LPH) the car hasn't ever given me a problem. Took a while to finally get the tune on point, but that was because of software issues, a minor vacuum leak in the PCV hose, and a tweak to my PCM "fingers", the car is now running better than ever.
Good Luck, and I say go for it and don't look back!!!
