It would be cheaper to sell and replace it with a bigger intake like the TFS-R victor JR, RPM etc...

To properly port the Cobra upper/lower intake you are looking at ~ $400. You can try www.flowtechinduction.com or www.per-race-engines.com
It may make more sence to switch to a different intake depending on what your combo is and what you are trying to do.

1. 350 at the wheels or at the flywheel?
2. Stock upper w/ ported lower on the Cobra will get you 350 flywheel hp IF the heads can flow enough. Probably should consider porting your GT40's or stepping up to better heads.
Here is a simple combo w/ Cobra intake that made 300rwhp-

edoit: BTW- 42lb injectors are WAY too big for your combo.

For 350rwhp you will need serious heads. AFR185's w/ pro-port work or TEA Twisted Wedge heads ported, 11:1 compression, Big cam too.
A more realistic goal would be 300rwhp. 350 means over 400fwhp and that is probably not going to happen w/ off-the-shelf parts. My setup hit 315rwhp/326 rwtq.

More than one way to skin a cat. Hopefully more folks will chime in w/ their combo's.
I have ported Twisted Wedge heads,
Typhoon intake (chinese copy of Edelbrock Performer RPM) w/ cleaned up lower,
cam w/ 228* duration at .050" lift on the intake and .570" valve lift.
Your cam/piston to valve clearence is all about the timing events, NOT your lift.
70mm throtlle body, 76mm MAF w/ 24lb injecotrs, adjustable fuel pressure regulator and some dyno tuning time to get the pressure right. Stock airbox w/ K&N.
edit: Longtube headers, offroad H pipe w/ MAC mufflers= LOUD.

All the head you will need is AFR 185's and 6500+ RPM other wise go with more cubes. And if you do any port work make sure it is someone who knows what they are doing. Gasket matching and stage 1-5 is worthless ![[Roll Eyes]](rolleyes.gif) , and not the proper way to port. PM 93pony and he will point you in the correct direction. He can also help with getting the correct cam. Another note on porting the good guys are real expensive, so try to buy the best head to start. Then you won't have to port them. Another side note is that hp numbers and dyno queens belong in supra message boards not here. Build you car to obtain a certain ET Goal and plan on working more on hooking up and less on that 350hp goal. Trust me I have a car that dynoed 307 hp and runs 12.1s, but only because it hooks real good. Traction is more important for ETs then hp just ask you local 03 cobra owner. ![[Wink]](wink.gif)

Oh ya I should list my combo too. ![[Big Grin]](biggrin.gif)
347 10.5 to 1 (no need for a 347 just a 306 + better cam and more RPM will result in the same power) Example: Jim's(fasterdamit) and Heather's(91Pony) cars ![[patriot]](graemlins/patriot.gif)
AFR 185s
X303
EFI RPM
Mac long tubes
3" prochamber and 3" mufflers(Force)
AOD 3000 Stall
3.73 Gears
Car has not been to the track since long tubes and UDP so we will see if I can crack 11's this Sat. ![[Cool]](cool.gif)

Not sure if the X will pass smog. I do know that the TFS stage II can pass smog even tho it doesn't have a CARB #.

Custom best $350-$400
OTS good $250-$350
Ford racing OK under 200
Worry about the cam last after you have gotten the rest of your combo together.
Trust me I started with an E303 worst choice ever.
Now I have a X303 Ok but not optimal for my combo, but will pass smog for me.
And I will be putting in a custom right after I smog. Money wasted.....
What are you after, and don't give a HP # give a full description with how much you drive(somg???) and what kind of ETs you want. Then others will give you there combos and let you know what not to due from their mistakes.

You will need different heads for sure
You will need a different intake for sure
You will need a different cam for sure
You can trade the 42s for some 30s not a problem
Your best bet, and cheapest combo is to buy a cheap supercharger, and be done with the whole thing. That motor with a good tune and a blower will run in the 11s with the right hook.
Here is my cost to build my car.
347 kit $1000
Machine work $500
AFR 185s $1200
X303 $100 used
EFI RPM $400 used
Mac long tubes $350
Exhaust free I have friends
then you will need a good rear end with 373s $500
Good tranny/clutch setup $350 (assuming your tranny is OK)
That is already over $4000, so it goes to show that a $1900 supercharger with the motor you have listed is the cheapest way to go.

Speed costs money, how fast you wanna go??? All I wanted was about 300 RELIABLE rwhp, and I have spent over $5000. It all depends on how long you want the fuse to last. Just my $.02

Profound statement. Most people don't realize the cost of small accessories in building a combo from scratch. Since the purchase of my 'notch roller, I've spent over $150+ on new sensors, ARP bolts and misc. other things to make sure they won't be a problem in the future.

Only thing i would even consider on a factory cobra intake would be extrude hone. I kinda think this will be a sought after piece yrs from now so i would leave it alone and get an aftermarket intake like edelbrock or some others. Good luck.

Yup, it was a bit pricey . My only used parts were the block(which was free), fuel rails, intake, and rockers (used 100 miles). My original 239,000 mile engine is still complete from upper intake to drain plug, water pump to pressure plate. I just wanted a new engine because I am a picky bastard and didn't want to touch my original engine for any parts. I know that there is nothing wrong with used parts, it's just up to the owner and his/her budget. I just trust new parts more than used, because I drive 90-100 miles a day.
