That will get you close. If you are gonna get the FAST just have it ported and get some heads to go with it. I'm at 387rwhp now and I plan on adding a p&p 90/90 with either afr or trick flow heads on my mild cam.

With a good set of heads added to the mods that you just listed you should be right at about 425 rwhp. As for the cam, u should get a Patrick G cam cuz that guy knows his **** when it comes to camshafts. I have the MS3 and it's OK. Power up top is UNSTOPPABLE, but the only problem with that is power isn't kicking in until late 2nd gear/ or around 3rd gear. Just something 2 keep in mind when considering a big cam.

Will be tough to achieve without some better heads. But you'll get close

I would say to get what I have, but I am a couple hp away from your goal.

If I were you I would go with a G5X1 cam and 5.3 heads, and you will have a good street DD car. The best part is that you won't break the bank.

i would go with an ls6 intake. it gains power and torque over the entire rpm range. the fast intake will loose alot of low end horse power and torque.

Yeah it won't be a DD once I reach my goal but I will be driving it more than racing it..

I'll take a look at these....thanks

I don't think you'll make that power to the wheels without heads. And you'll need some bigger injectors too.

I would estimate high 3's, 380ish maybe. My friend had a small cam, stock heads and bolt on's and made around 360-375. I can't remember the exact number it was awhile ago.
