big cam statement I wanted everybody to know about the cam I got from ls1 speed they custom ground a comp cam 232-240 595-610 lift cam at 110 lsa for me and it and my pacesetter long tubes and y pipe at my home in a few days! Most people on this site when comparing big cams only talk about the magic stick which is a 236-242 603-608 lift cam and makes power between 2600-6600 rpm roughly ad is a 113 lsa.The other cam is the t rex which makes power 3500-68000 roughly and is 238-242 605-612 110 lsa. My cam starts making power sooner than the t rex and for longer and I don't have to have 410 or higher gears. The reason I did not go with ms3 is the powerband and the lsa. The other cams are the f13 or 14 which I looked at but they don't make the as soon as mine and not for as long. And if you want to go even bigger you can I selected this size because that was what they said would be the biggest cam I could put in my car without clearance issues. Just ask for mike at ls1 speed.com

I'm confused too... what is it that you are trying to get at? I think you are trying to say the existing big cams out there aren't all that drivable in real life conditions because of the narrow powerband that they have.. but you also seem to be saying that a big cam is needed to make power.... not true either. Get your parts, and give us a dyno result ( I won't bust on ya for a graph... I can't post mine. 
)

to be honest...there are some great cams with around 10 duration differnce between the intake and th exhaust... and that cam will probably do great...
but its like comparing apples to oranges....
the other 2 cams you mentioned all have put down BIG #'s....and they all have their good spots and bad spots....
and on stock heads...you might have a winner...but once you get some serious stage 3 heads with those cams...and the air is flowing about as good as it possibly can...more duration and lift...usually = more air = more power....not necessarily wher YOU might want the powerband.... a TREX is definately a DRAG cam...High RPM and lots of airflow.... you have a "G5x2 110lsa".......
I personally have a favorite of a 220/230 cam....but that doesnt mean that it makes more power than a 224/224 or a 230/230...
maybe if it has an extreme ramp rate on the lift....but still pushing it...
I dont mean to "shoot you down"
but please put your #'s and graphs and pictures where your mouth is....
oh yeah...find a car with your exact setup...and only thing different being the cams...and compare...At The Track

Numbers are only a snapshot of specific points that in a low resolution manner describe the cam. Two cams could have the same specs @ .050, but they could have different ramp profiles.
Good luck when you get it runing.

cam I will put my dyno numbers up but I think a lot of you guys took what I said wrong I'm not saying the other cams are bad but I found a cam that is rated at 2500 rpm to 7200 rpm power band the t rex is 3500-6700 you are correct that maybe those other cams put down lots of power but until I dyno I can't argue that with you but I do know racing or not racing I rather have more of a powerband. I wanted to offer other guys some other choices for cams and I saw what the trex makes at 2k or 3k from one of the guys on the foum and it only made 80 something horsepower. That would not work for me I have a daily driver and know for sure I'm making more power than that. I love this forum even if I'm new I'll bring what I when I get it.

i go by dyno powerbands not "advertised" power ranges. i bet you your cam is no different then any of the ones you listed. who cares about 80hp @ 2k rpm when you've got over 250lb-ft of tq. you do know that hp is a function of tq?
when looking at daily driving you look at the tq curve, not the hp curve :umm:

would be I'll be you money when I dyno my car I will make more 80 foot pounds of toque at the rear wheels at 2k rpm. I talked to the guys at thunder racing and they told me you could expect it to peak at 6700 rpm. I want everybody to know I comparing my cam which I'm very happy with if you are happy with your cam so be it I'm just providing different opinion on cam choices.

i'd HOPE you would make 80 ft-lbs of TORQUE at 2k rpm...
you go on ahead and make your "80ft-lbs of tq at 2k rpm" while the rest of us will have ~250ft-lbs @ 2k rpm and 300ft-lbs at 3k rpm
i think your confused, pick up this discussion when you have the dyno to prove your point. w/o any data your not aiding your cause.

um i make 120hp and 250tq at 2500 where we started the dyno and im making 442 @ 6800 on hp and still in the 430's at 7200 where it falls off so thunder could say the power band is 2500-7200 if they wanted to. without a dyno curve from your car this argument is useless.
