Narrowed my cam choice down to 2!
I looked into the Tick Performance Polluter Cam, and they "brag" about how much torque they have on the low end. I was just comparing my dyno graph to theres and @ 220rpm i have a little over 300 ft/lb of torque and the Polluter cam has a little over 300 ft/lb of torque @ 2900rpm but after that it gains quick!
Well these are just dyno graphs done on different Dynos, but the cam is intresting i want to see what it does at the track! I think i might have to wait.

bear in mind that tq will mean little with a stall converter..not to mention the trex cam makes similar tq at low rpms. i don't think tq at a given rpm is the best judge of a cam. we shall see. it will run like all of the other big cams and not offer enough tq in the low-midrange to tell a difference other than on a dyno.
I had a G5X3 112 LSA in my old motor. It dynoed 395 horses and 383 ft. lbs tuned at Texas Speed. I was happy with it. Driveability wasn't horrible either. I was (and still am) running a SPEC 3 clutch. I know 
. I'm doing an MS4 and PRC Stage 1 heads on my new motor. It isn't in the car yet so I don't have numbers for you. Either way. The G5X3 was a good cam. Also, don't change your mind because of the numbers. I sold the cam to a buddy and he dynoed a little over 410 horse. Some cars are dyno queens. Hope this helps.

As Far As Sound And Performance Factor On A Non Daily Driver I Am All For The Ms4....my Cam Is Close Just Not That High Of Lift...i Have Yet To Get To Fire It Off Though...soon Very Soon.

We recently did tons of engine dyno testing with camshafts of different sizes. I just finished up a new lobe with the help of the engineers at Comp cams that worked pretty well for us. We were able to develop a 235/240 camshaft that makes within a couple hp of the MS4 camshaft & gives better p/v and great power across the board! I personally think this camshaft will be one of my favorites when we start installing them in customers cars. After dyno testing it next to the MS4, Torquer 3, and a few camshaft mentioned in this thread I think it's really a hard camshaft to beat.
The post someone above made claiming you'll see 10-15hp difference from one large cam to another is completely untrue. We tested 231/234 torquer all the way up to large 244/248 camshaft & what we found is the power between all camshaft we tested in this area was within about 10hp. The difference in TSP camshafts is we try to build the good peak power while keeping the torque peak at a reasonable rpm & making good power across the board. The MS4 made nearly identical peak power as the 244/248 camshaft but with a torque peak something like 500-600rpm earlier.
Give us a call in the morning & I'll gladly provide you with engine dyno testing graphs to help you research your decision. It's really hard to purchase a camshaft because there's lots of smoke & mirrors online. What I can offer you is our dyno testing that was done on a independent dyno. If for any reason someone doesn't agree with my dyno results, I'll galdy reproduce the tests as long as the person questioning the results pays the dyno fees if my numbers are correct.

The baseline engine for our dyno tesing had a fast intake, prc spring kit & dyno headers. The baseline power was 416hp & 422lb ft of torque. The MS4 install made power output go up to 511hp & 440 torque. Power output was up nearly 100hp while making as much power as the smaller cams & stock camshaft at 3000rpm!

02TransAm I'll take that bet with you. I've dyno tested XER lobe camshafts very similar to the camshaft your discussing. The MS4 is offered to our customers because we feel it's the best possible max effort camshaft available so far!!

I think this is due to lack of tuning skills. At our shop one of the mechanics daily drives his MS4(111) Z28. I have drove this car several times and you can put this car in 6th gear(3.42's) going 45mph and have no cam surge at all. The car pulls hard from down low. Kinda of suprised me !! Every car acts diffirent though. I have seen some cars with a TQ3 act up more than a MS4. Either way the MS4 is a great cam !!!

any half way descent tune should be able to roll in 6th gear at 45mph. the test is a first gear roll at 5-10 mph. if your car isnt bucking and surging while searching for a parking spot at the grocery then you have it down. and the fact is none of these big cams will be able to do that. it doesnt mater what tune you have.

G5x3 vII lsa ??. When used in my combo it made 360 rwtq at 2800 rpms and then jumped up from 3000 rpms. Peak torque was 445 at the wheels. 490 rwhp was pretty good too.
What parts are going to be used with your cam ??

your idle is all in the tune, a personal preference on what you will tolerate. If you think the G5 will make more power by all means go for that. But if your just looking for a nasty good power making cam, wait a bit and see if the polluter lives up to all the hype. It might be a good option and it isnt played out yet.
With the MS4 you do not have to do that, the MS4 so far is the biggest cam you can have in a stock LS1 motor w/o flycutting the pistons.
