I know this is kind of a stupid question because it will have a lot to do with my driving ability, but will my car be capable of mid 12 second quarter mile times with this setup? My current setup consists of a 347 stroker, comp cams 270 magnum cam, K&N Filter, MGW short throw, O/R h pipe w/ slp lm1's, upper/lower control arms, subframe connectors, and 24lb injectors. There might be a few more but that's all I can think about now. For the future I will be port/polishing the heads/intake and probably going with a custom grind cam but i'm not sure yet. I will upgrade the MAF and Throttle body but I have no idea what to go with. Any suggestions? I will also buy strange 10 way adjustable shocks and steeda springs. Right now I am debating whether to go with 3.55 or 3.73 gears. What do you guys think of this setup and is it possible to hit the 12's with it? What kind of power should that put me at? I also need to be able to pass emissions. Will this setup give me any problems with that? I do not want to run forced induction I just want it to be a solid N/A daily driver. If you guys have any other ideas for me let me hear them! Thanks everyone

Well, with the 347 that will get you there easier. You will need new heads and an aftermarket intake.
The stock intake and heads, even ported, aren't worth much. You're on the right track since you're getting your suspension built up first, but you still need the engine to make the power.
Go with 3.73's if you have a 5 speed or 4.11's if auto. How much are you wanting to spend on the engine?
You could get some AFR 185's and a GT40 intake or Edelbrock RPMII intake. The AFR's and RPMII will make a lot of power.
Give us a budget and it will be easier to point you in the right direction.

he is correct what you need is induction sytem i have tfs stage 3 cnc and cam with r intake you would be flying.keep trying different lanch rpm and modulate throttle really work on getting out the hole.and shift at max hp rpm.drive it like you stole it. lol good luck call ron at fox lake racing he is really nice guy and can you hook you up just tell him your money and hp u would like

[EagleAutosports]

As is, it'd be limited even though it'd have a lot of torque. You must upgrade the heads and induction, to get the most out of it. Do that, and 12's would be within reach.

I'm not sure what you mean by max RPM, but if your talking about shifting at redline (about 6K RPM) that might actually make your ET's higher. HP actually runs out at aroun 4500-5500 RPM depending on your mods and just what your car likes. So waiting till redline to shift would be loosing valuable time. Just try different shift points and see what is better and what's worse.
I have a 180K mile motor with only LT headers and K&N filter, and I shift at about 4800ish. But I'm still new to the Drag strip and my fastest time is 15.6 with very little traction.

Well I'm definitely on a budget that's why I'm looking to keep my stock components. I'm currently in college so I don't have much spending money. I've been reading up on my gt 40 intake and I hear that its a pretty decent intake once it has been ported. I'd like to keep it especially because I like the stock look under the hood. Now I'm pretty sure I could save money for new heads, but they would probably be the last thing to go on the car. I'd like to finish up the suspension first. Porting the intake is relatively cheap so I think I would have that as my setup for a while and then once money permits I would go with a Black RPM II intake. I love the look of them. What would the car be running with the aftermarket heads/ ported intake and the suspension upgrades? Oh and would it be a good idea to get a custom grind cam or will the one I have in there be alright for what I'm looking for?

with your setup, you can go high 12's , but your going to have to drive it there, testing and tuning at the track, and some type of slick or drag radial will put you where you want to be, the stock heads arent helping, or intake, its choking the 347 cubes, but with timing adjustment, and good strong launches, you should be almost there, then after you upgrade you'll be there easy

[302Feen]

Do you have the stock GT intake or Cobra intake?

If you have the Cobra intake I would save for a decent set of heads. Just something better than the E7's. The Cobra intake will flow good ENOUGH for the 347, but the heads are starving your engine.
GT40 heads are about $400ish. Those would be better than what you have now. Because even if you port the intake, the stock heads are going to restrict the port job anyways...

[v6stang3215]

I have a 95 mustang cobra with the gt40 heads and intake.

[v6stang3215]

My original plan was to port the gt40 heads (which are on the car right now) and the gt40 intake.

[302Feen]

Oh... I was thinking you had stock GT components...
Well... the GT40 intake (unported) would probably flow well enough, but the heads will still restrict that much displacement. A really good port job on the heads would be worth the money more than porting the intake...
I've seen a few people on this website with the 347 and cobra intake. The GT40 heads aren't horrible by any means, maybe with enough porting and some 1.7 roller rockers and a really good pass, you might be able to get into the 12's.

My fault about earlier I was thinking you had GT intake and E7 heads...

Now you are talking about the GT40 tubular intake or GT40/Cobra intake?

[v6stang3215]

It is the Cobra intake and don't the cobras already come with the 1.7 rockers?

[v6stang3215]

So is porting the gt40 heads and intake a good idea? Or would my goal for 12's not be reached? I could also upgrade the cam if that would do it.

Cobra's do come with 1.7 rockers...
Porting both the heads and intake will get you close. If you got good traction then it's doable. I don't remember if you have drag radials or not but those would help big time.

[v6stang3215]

Is it true that with the stock heads and intake ported I'll make more torque? I just have street tires right now but I would probably get some nitto 555R's.
