how do u think it will run i think it will be fast as ****

Stage 3 heads run in a limited RPM range. depending on your cam set-up around 4500-6000 is their range. It's very short but powerful. Absolutely terrible for street drivers. Excellent for track runners because of their short band. Just because they flow better doesn't mean they will perform better. The more flow a 2v head has past a certain point I think 195cfm??? they will begin to lose low end torque very fast! Most stage 2 heads flow about 204cfm's which loses a little bit of torque but the cam compensates for the little bit lossed! Stage 3 is way out of your league if you have to ask any typ of questions about them!

What if he got the cams, got it tuned and just waited till he had enough for a blower? Would it hurt the car? I'm just wondering cuz spending all that money at one time would be kind of hard at least for me. I think I'd rather do cams and heads and full bolt ons and then wait and get a badass blower kit when I have the dough. Is that a bad idea?

It wont hurt your car but you will lose power and not be able to get any power on a stock engine N/A.

I have Patriot Stage 3's on my car. It made 320rwhp/335rwtq. No complaints here. I need bigger cams tho. What cams are you going to buy?

Well when I was building my NA 5.1L I had stage 2 heads and cams and long tubes with a stock intake except the 75mm TB and plenum. I dynoed the engine on an engine dyno and it put out 392 hp which is about 347rwhp.

Is that with or without accessories? 347rwhp is Huge, and I'm gonna have to see your car vs mine to believe you got me by 30rwhp. I know I'm on shorties, but damn. Your on low compression right?

Are you gonna be at the March Madness in Clarksville? I think I'm gonna show up.
