GMPP ASA Cam

so the stock 806's dont hold the cam back too much? what should the rev limit be set at?
so lets get a list going of the cam swap
1.cam
2.LS6 springs
3.locks
4.hardned pushrods (good measure, not required.)
5.LS2 chain
6.Oil Pump
7.???
anythign else?

gaskets..
spring compressor
metal rods to hold the lifters up inplace since you are not removing the heads.
i bought a pair of 04 ZO6 springs.. say they will handle .580 lift.. alsmost the same price as the 02+

And I wonder if running some 1.8 rockers would affect the spring life at all. I say that because one of the main reasons I'm getting this cam is the ability to put in a set of LS6 springs and never have to worry about them again. I mean if I could get a little more power (can someone explain to me how I would get more power using 1.8's over the 1.7's or whatever the factory ones are?) using them without sacrificing spring life, then I'm all for it!

"The lobe lift of the cam is increased by the ratio of the rocker arm to produce the final amount of valve lift. A cam with a .320" lobe lift using a 1.50:1 ratio rocker arm will have a .480" valve lift (.320" x 1.50 = .480"). If you install rocker arms with an increased ratio of 1.60:1, with the same cam, the lift would increase to .512" (.320" x 1.60 = .512"). The engine reacts to the movement of the valve. It doesn't know how the increased lift was generated. It responds the same way it would as if a slightly larger lift cam had been installed. In fact, since the speed of the valve is increased with the higher rocker arm ratio, the engine thinks it has also gained 2? to 4? of camshaft duration."
I think 1.8 rocker arms would have a slight impact on spring life but I don't think it would be enough to worry about, atleast with the ASA cam.
Running 1.8 rockers on the ASA would bump you to .555" lift and add a couple degrees to the duration of the cam. Using 1.85 rockers would bump gross lift to .571"....I'd say 1.8 would be the max you'd want to use LS6 springs on the ASA. Any more than that and you're increasing ramp rate and gross lift enough to warrant some periodic valve spring checks. My 2 cents.
There's been a couple threads waaay back about heads to use with the ASA. Can't remember what the consensus was, but I'm going with some cnc'd 243 castings eventually.

where could you buy this cam? Obviously it would be a better choice than a GM hot cam for the LS1?
I'm planning on buying some patriot ported LS6 castings, so with those heads, this cam, some crane valve springs, and some hardened pushrods and possible some crane 1.8 rockers....sounds like a pretty decent setup on a LS1 daily driver or what?
I was originally planning on the Gen III hot cam til I found this thread, and listened to the idle....

All right, I understand the rocker ratios now. Thanks!
Not really sure if this would be a good cam for boost with all of its overlap. I do think it would do good with some N2O, however.
