Engine Needs Bigger Balls

Im in the process of making a decision about what cam and rocker ratio to use in my car. I see a cam from Abbott that uses 1.6 and it matches the heads and intakes they have. I see a lot of people going to G2 cams. People with 1.9 and 1.8 rockers. Where can I get a G2 cam? Do they last for everyday drivers? I drive about 350 miles a week. I don't mind gass prices. Im trying to make the car more agressive without supercharging it. My goal is 1.5 hp per cubic inch. I don't expect to get there overnight, but for now I'd like a little more power. What's the highest compression ratio for the 3.8? I know stok was like 9.4:1.

[98 3.8]

I'm not sure about the compression, but I know you can get the GT2 cam from www.zzperformance.com

Is there anything that works greater than the GT2? If I change the rockers to 1.8 will that help make more power?

Intake Lift .317" (.507" lift at 1.6:1 rocker ratio )

Exhaust Lift .317" (.507" lift at 1.6:1 rocker ratio)

1.9 rockers and stock cam is about .490 i think. don't do 1.9 rockers and high lift cam. just one or the other. no reason to do that. get the cam you want with the lobe and lift you desire. no reason to add specialty rockers on top of a cam.

maybe some of the more advanced cam gurus will chime it but there are limitations on lift before valve guides get in the way and stuff like that.

try and put together a package of stronger valve springs and pushrods along with the cam. leave time and money for tuning as well.

I am here to say that near .520" lift is all you can get on stock heads.
Anything over .500" lift on stock heads is pointless anyways, and just harder on the valvetrain.

I don't think you will be able to hit your goal with out forced induction or n2o. I could probaly be done but it would be cheaper to go boost or n20. Your goal right now is 346.5 231 x 1.5 .

dang
350 hp would get you 13.0 easy

I guess I need to read the debates in the FID section about Turbo vs Super. I'm leaning towards the SC, but Im going to read more to support my opinion. Thanks guys
