It doesnt take much to make 350 rwhp on a 99+ cobra. many are around 325-330 without removing the heads and full bolt ons and porting the intake.
Hell I should be in that range with unported stock B heads on my car. Take a 99 cobra(c heads that are much better), a nice set of stage 3 cams, port the heads, longtubes, and a nice tune with a sullivan intake and you are damn near at 380-400 rwhp. Bob cosby, Joe lynch(old combo) and a few others out there.
Hell for me to get 350rwhp we are talking 2500 for the cams/springs(titanium), the LT's and x pipe with my tune. Not bad for a 281 cid.

350rwhp is not the norm. Most the guys making 380 with a cobra are running a stroker motor also. Most ported head and cammed cobras I've seen are making more like 320-330rwhp and about 290-310 ft. lb. torque. What sucks is that without a stroker the torque is weak in comparison to the hp. With your B heads I'm not seeing you making 350 rwhp easily without huge cams and a car that is no fun for the street. The B heads are not a high velocity port head to start with and porting them makes for a poorly driven, top end only street car short of a supercharger that is. Your hp curve probably won't even start to hit until over 5,000 rpm. Plus you'll need 4.56 gears to even make it worth while. You can add significant hp to the cobras, although the torque sucks and the powerband is moved sky high. No fun for a streetcar IMHO.

No. I won't the gears do not cause yhou to gain hp. Infact Dynojet has even said they will cause you to lose some rwhp. gears not not give you hp. Thats a proven fact
stock heads, crower stage 2 cams, Longtubes a dr gas o/r x, and the sct tune I will be near 330 rwhp. Putting in 4.56's will not boost my hp<laugh>

I'm laughing right back at you. For the third time I'll try and explain this to you. I never said gears give you hp. You are right, if anything you will dyno less with more gear. What I was saying is that with porting the low velocity heads and putting in a big cam, your power band will be moved up so high that you will need more gear to get into that powerband quicker. Otherwise you will drop too much rpm between shifts to utilize your new sky high powerband.

Again I never said i am porting my heads. I am leaving them alone. I am happy with the 260cfm in stock form. I am also going to be using nitrous so that 4.56 gear will be useless anyways. Good call on that one buddy Nitrous + 4.56 gearing= no traction at all.
I already stated you will dyno less with more gear. Thanks for re stating it again

If i am dyning in 4th I wont need to worry about shifts to drop my rpms? Again with a tune, which I have, my rev limiter is at 7500. I am not too worried where my power is met at, but thats where the NX comes in up until 6800.

Go back and re-read the post's slick. I was repleying to your comment about how you thought I was saying that gears gave you hp, which they don't. You tried to explain to me how more gear will cause you to dyno lower. I completely agree with you and was just trying to state this. Please go back and read over the posts before you spend anymore time arguing with yourself. Anyway good luck with your car.

No you were implying on a car that is set up differently that i need more gear to make a certain rwhp. That is wrong.
You stated most guys making 380 rwhp in cobras are using strokers. Thats also false as we know strokers are **** and crap out around 15k. Hence why we use the big bore instead.
Coming from someone who says the 99 cobra makes 245 hp I will take what you say with a grain of salt

Ok, for the record......this is the 4th time of telling you this in not true and I have never said this. Go back and read. You need the gear to utilize the hp, not to make it. Here, I'll even say it in a different way in hopes this will be the last time I have to explain this to you. Gears do not add hp!!!!!!. When you mod your car, you usually make more hp, albeit at a higher rpm. You use gears to keep your rpm up into your power band. Once again, GEARS DO NOT ADD HP. This is the final time I will explain this to you.

I'll kindly ask you to GO BACK AND READ(again). I said this when I thought the post was about a 94 cobra, then later I realized it was a 99 and I corrected my mistake. I will also take what you say with a heaping spoonful of salt. It has taken me 4 posts to explain to you that I agree with you and that gears don't increase hp, they help you get into the rpm range so you can use your hp. Get it straight.
Can someone else please explain to this guy that I am agreeing with him, and that gears don't increase hp. Maybe he'll listen to someone else.

This is your comment and quote
Why are 4.56 gears needed to make 350rwhp on that set up where a 4.30 gear cant?
That right there states my 4.30's isnt enough and need to get rid of them and get 4.56's to make the 350 rwhp. Again 100% wrong. Yes gears may help me use my hp in a DRAG RACE, but what you just stated above it WILL NOT ALLOW ME TO OBTAIN A HIGHER HP reading on a dyno, which is what you stated above.
I will break it down barney style. 350 RWHP= PORTED HEADS+ CAMS+ 4.56'S Vice 350rwhp= PORTED HEADS+CAMS+4.30'S according to your post above.
100% false and that is why my argument is about.
Maybe you are confusing yourself with a drag race verse making hp on a dyno. Gears are not needed to make hp on a dyno. They are needed to get me into my powerband faster so I can get a faster ET.
Actually I'm an X 4.6 mustang guy and know quite a bit about these cars myself. What I said is that with ported B heads and the kind of cam you would need to reach close to 350 rwhp, you will need 4.56 gears. I wasn't talking about a stock car.

99+ cobras can put down 350rwhp with cleaned up heads, bolt-ons, and modified stock intake. Pre-99 will take a little more. Bob's FS car had cleaned up Mach1 heads, stock intake, 10.5:1, and bolt-ons and put down 356rwhp. Saw the dyno sheet at NMRA 2 years ago. -Mark

How many times has Redneck Z stated that gears do not add HP?

Black fangs car does not have 10.5:1 compression or mach 1 heads. Big difference.

No offense, but have you been drinking tonight? I have been saying EXACTLY what you have for "5" times now. Gears DO NOT help or MAKE hp on a dyno. In fact, you will dyno lower with more gear. They are used to get you into your powerband faster and help with your ET's(just like you said). This is EXACTLY what you just said and EXACTLY what I have been saying for my last 5 posts now!!!!!!!!!! Please process this information!!!!!!!! If need be, go over all of my posts like 5 times and then maybe you will see what I have been trying to say OVER and OVER and OVER and OVER and OVER again!!!
