Ms3 guys come in.
I do notice that all the sheets posted of the big cams are from at least 3000 rpm and up.....
Low end? You mean torque numbers or hp? Seems most make 250 rwhp at 3500 to 3750 rpm...which is close to the stock (bolt-on) numbers, then the cammed car's hp climbs way more than the stocker...
that part that might hurt you is, those dyno pulls were with a shitty pacesetter ory, through the stock slp center mount exhaust catback.
this will power will be laid down by a t56

I have the ms3 on a 112lsa. I am running stock 241 heads, and the stock ls6 intake manifold. I made 412rwhp through a 4.10 geared 10 bolt.
I then added a HSW wet plate kit and had it tuned for it. We took away 9* of timing so I can run up to a 200 shot safetly. The car still made 400rwhp on only 21* of timing. With a 100 shot, 517rwhp. 150 shot it laid down 600rwhp and 639rwtq. The car is a animal on the bottle, and runs pretty well on motor as well.
I put in a moser 12 bolt with 4.11's last winter, but havent been back to the dyno sense, cause I havent done anymore power mods. I am not sure what it would put down through the 12 bolt.
now, as far as street manners, I went through a few different tuners until I was STREET happy. Tuning WOT on a dyno is one thing, with the ms cams, but a good street tune is another. My last tuner dialed it in on the dyno with the nitrous, then out on the streets. Needless to say, I get mid 20mpg's on the highway with the 4.11's on a 28" tire, and I can cruise at 1300rpms with NO surging. I get a tiny bit of surging at 1700rpms, but not enough to get annoying. I DD my car as well. I have taken it on 900 mile one way road trips, getting great mileage without a single problem cruising with the ac on.
I have a ls6 ported oil pump, ls2 timing chain, thunder racing 7.425 chromoly pushrods, prc .675 golds, titanium locks and retainers etc. My revv limiter is at 7200rpms, but I shift around 6700rpms on the streets and 6900rpms at the track. Looking to add a fast intake and some heads this winter.

does it really feel really sluggish with the 342's? How would 373's do?

im going to forge it this winter to handle a bigger shot of nitrous and be safe.
to be honest, I liked my 3.42's more then my 4.11's. The 3.42's with the ms3 made the car a beast on the highway. With the 4.11s and nitrous, I am shifting every 3 seconds.
sometime this winter when I rebuild my 12 bolt, Im going to put 3.73's or 3.55's on it.
