I started with a comp xr281 on xr lobe's 228/230 @.050 .571/.573 with stock heads on my 04 gto.
stock everything at first. stock ex and all. loved it . then put a 150 wet shot on it and loved it more.
then went with long tubes no cats and a full 3" back half.
ran great.
then bought afr 205's at 59cc and put a tr224 in and was very unhappy the low end was unreal but the top end sucked.
i even got worse mpg with the tr224 than the xr281. 21 with the tr hwy to 23.5 with the xr
then went to a xer 281 same as a tourqer but bought from comp 232/234 i think .587/.589 lift on a 112
loved this cam insane low end and top end pull with .040 cometics with the afr's and a good tune. plus it loved a 150 shot
then ran a 238/242 xer .605/.609 on a 112 installed on a 112
this cam took a little to get used to. once tuned idled sick as hell but lacked low end but made up for on the top end like pulled to 7k .
even with the 150 shot it did still not have the insane tq like the 232/234 cam had but once i raised the shift points to 7k it grew on me still ran a 11.29 with a shitty 1.9 60 with a 150 shot turning it on at 3800
all these were ran in a heavy *** gto that i drove between mi and sc and mo 3-4 times a year.
the 232 cam still was the best combo. now i have a 243/251 sls lobe'd .624/.624 on a 110 plus 4 but now the car is a drag slash street car and will not be road tripped
the low 230's had the best all around pull to 6800 but yet enough tq to set you back at lower rpm's and got got better mpg than stock
i did have a edge 3500 converter for all cams untill now.
so hope this helps.

Im running with a 224/224 and its good for me. I like a very well street mannered car though. I probably could have gone bigger though to 230's. But dont take this the wrong way I love to see 240+ cars, they sound really great! Its all based on how you run the car and your personal tastes.
My previous set up was with a Comp XR277HR 224/228 which was a nice quick combo with very steetable manners.See my sig for my present set up.It is also very streetable but a whole lot faster than what I previously had.So I guess it's like this...set your car up the way that makes you happy because everyone else's opinon doesn't really matter.

I have been tempted to go bigger than my TR224-112 but I really love the low end nd mid I get from my combo.
I'll break down and re-cam next year but I will ask one of the specialists on the board for a custom grind to try to help with the elevation I deal with which is ~ 5100'.
Anyway, good luck and keep us posted.

My car has a 234/238 .598 .605 on a 112. Comparing it to a friend's car with similar heads and a 224/226 .575 .575.... I would never go smaller than what I have. His car is a dog. From a very, very slow roll it feels like it pulls harder but after 3000rpm it feels like I have twice the car. I have no drivability issues at all. It bucks at 1200rpm when it is cold outside and the car is under no load. Its not even bad and I changed my driving habits a bit to compensate. As far as the low end is concerned I just don't get it. I never race below 3000rpm. If I am under 3000rpm I am at part throttle. It is not like my car can't get out of its own way. Need to speed up a little, hit the gas.
If your car drives like **** with a stock bottom end you need a better tune more than likely.

the xer 281 is what you get if you buy it from comp. and it is a thunder racing tqer2 i think. comp has the specs on their site. it is a 232/234 @.050 xer lobes .587/.589 lift it was a great cam i have a great tuner and with a good tune it will idle at 750 rpms and pull like a freaght train into the upper rpm's

I have a 228/232, made 404/375 and 415/378 CORRECTED.......
Now i wish i would have gone bigger, maybe 23X/23X....
But like other said, i still have STOCK H/I(ls6) on my car. I am sure that if i replace those first that i would benefit more from my cam
