Anyone just running a ms3 cam 112 lsa all stock ls6 with valve train upgrade? I'm looking into ms3 cam valve train upgrade myb ported polished an milled ls6 heads. I have ported fast92 an ls2 tb with full exhaust also with porting milling the ls6 heads how much power would come outa them? An what's a good place to send them to?

That is the same setup I'm planning on running soon. Hoping to make 430-450 whp. 430 with same CC heads, 450 with milled. I'm leaning toward not milling the heads for future boost, and using a thinner head gasket for a little help. There are V's running the MS3, they are on you tube from what I have found and I think Radeon ran one? Everyone says it is too big, and it is. But I dont care.

Also for heads =TEA/Total Engine Airflow IMO

Yea I know he had the ms3 he's local but he also had prc 2.5 heads

Yes, he had an ms3 and PRC 2.5's. I installed them with him. It ran good with that combo.

Ms3 is a nasty cam. With my prc heads it was good for around 450 rwhp with maxed out fuel injectors. I would say cam only would net you 420ish, but I have been wrong before. I actually considered using the ms3 in my 408 build the, ended up getting Texas giant. In the ls6, it was very driveable, nice choppy idle. I'd suggest that cam to anyone.

Your gonna give up a little bit down low but it will pull great up top. I really like that cam for LS1/6 cars and bumping the compression will help big time. 440rwhp should be pretty attainable in the V with that setup.

I have full bolt ons, 237/242 duration cam and a fast 90 and the car made 438Whp at 7k rpms on a dyno jet.
It runs pretty strong but honestly you would prolly be happy with somthing slightly smaller because this cam doesnt start pulling hard till just under 5k rpms otherwise its a dog down low.
But i got some heads im putting on and i just put a plate kit on yesterday so hopfully nitrous will fix any slow areas in the rpm band
Its nice to have high peak numbers but its overrated, im sure somthing with the same split but less duration would perform much better.

Depends on what OP wants. It's a good choice for the track, but will hold him back if drag racing or just on the street, having such a narrow power band. Every time you shift, you'll drop out of the power band, then lose time waiting to get back up. Running at high RPMs all the time will result in premature engine wear, too. The ideal cam for a cathedral port street/drag car on the radical side is the Streetsweeper HT or one of Tick's Stage 2 SNS cams.
