Winter Bolt-Ons
Winter Bolt-Ons So i have finally decided to start removing reliable factory parts with unreliable aftermarket ones. I plan on... ls6 intake, LT's, catted y, cat back, valve springs, timing chain, and a cam. The goal is to make 400 hp with these bolt-ons. I know its possible because there are quite a few people here reporting that type of power with the same mods. My huge question is what cam and springs(brand, lift/duration/lsa)? I know its asked quite frequently here but, I still can not make up my mind after viewing past threads and listening to them on ls1sounds.com. I want the car to be reasonably reliable after a tune and still make decent power preferably in the lower rpm range and yes... sound like it has a cam in it.
Help me out guys.

lol those parts aren't unreliable at all. the parts that become unreliable are the factory parts once you increase torque significantly (10-bolt rear and 4L60E's). you will make 400 hp at the crank with full exhaust (headers, true duals or y-pipe/aftermarket catback), a lid, a CAI and a tune easily. if you're going for 400 hp at the wheels, even a baby cam will put you there easily.

there's no way we can give you cam suggestions without telling us exactly what you want in the cam. all i can tell you is, when people don't know what in God's name they want out of the cam, they usually go with a TR224 because it's a basic, mild-mannered cam that gives decent gains and seems to work well with any setup.
you drive a hard bargain choco so here is a bit more of a description..
my car is a 99 Z28 m6 with the stock 10bolt and t56.
yes, i know the 10bolt will need to be replaced after seeing some power. hell it needed replacing 10k miles ago without seeing any more power than what my car puts out stock.
as far as mpg and comfort.. circa 15mpg min. and i need to be able to drive it everyday.
new setup will be:
ls2 timing chain and new sprockets
cam <---the big question
set of comp 918 springs
ls6 intake
LT headers (undecided brand)
catted y (undecided brand)
b&b catback
and finally a dyno tune
down the road i dont intend on spraying or going fi but if the need for more power arises(which im sure it will) ill snag a set of heads.
i want it to be a good street car with ~400 hp and near that in ft.lbs. as for sound, well, i want the mustang next to me to know that it is cammed...
i hope this helps.

if you're trying to keep good mileage, i would go for a cam along the lines of, oh, say 224/228. it won't kill your mileage, have very good manners if tuned properly, can still give you some 40 horsepower and will work pretty well with a blower. the torquer sounds like a good blower cam, too, but note that it's a lot more aggressive and will eat more fuel.
i'm not very good at all with engine internals, i only know the basics. if you want real tech guys to give you input, post this in the internal engine section. a lot of guys in the external section are wannabe techs like me
the internal guys know their ****.
