YA good find! THis is my first post WHOOO! I got a 2002 mustang gt with 35000km on it. Anyways im thinking of either buying comp cams 268 since its inbetween a stage 1 and stage two of vt. It was a good rpm range of 1600-5600 and lift is .5 so i wouldnt have to worry about clearance, and with that i would get my heads ported to a stage two to fit the 268 cams better. BUt ive been recently looking at used prochargers for around 3500 anyways if anyone has a deal on aprocharger let me know but what do you think should i do? Labour would be cheap my uncle has his own shop. I also just put on magnoflow exhaust, throttle body, cai and a short throw last month in my garage so if that helps. i was also thinking of putting on some 3 73 gears to avoid that low end torque loss. this wont happen till end of april when i save up some more money.
!!!! As for gears,especially if you are planning to stay N/A,DO NOT GO with 3.73's,the jump from the factory 3.27 to 3.73's isn't really a big jump of a notice for torque gains
.I did this mistake.We all know that the 4.6L lacks the kick in the paints,unlike the 5.0L,so 4.10's all the way,especially since you are planning on doing cams,and ported heads.When i was stock cammed,the 3.73's were....well....alright .After the cam swap to the VT cams,the 3.73's were.... ....!So then i went 4.10's last summer,and wished i listened to everyone on various boards,aswell as some good friends about going to 4.10's in the first place.Believe me,highway driving will not hurt you one bit either.I highway drive with my stang in the summer,and tell you the truth,i get better gas miliage,as weird as it sounds.LOL!Am not working the engine as hard.As for cams selection.Do a lot of reading,searching.ModularDepot.com is a good place to start as that site is for the modular guys,and is full,and i mean full of do it yourself guys with info,and they build,breath,race,repair there on steeds,plus are willing to help,and steer you to the right path
.Also VT is a sponsor on this web board,pm Scott@VTEngines ,or Jim@VTEngines.They can also give you some good info.These two guys are the best,very willing to help,easy to talk too,and awesome to hang out with too
LOL!Again welcome.good luck on your path for more hp!!!

THe specs for the VT stage II N/A cams i found on vtengines.com "Stage 2 cams are the perfect choice for ported heads and all out N/A street/strip performance. MUST BE USED WITH AFTERMARKET VALVESPRINGS. Aggressive idle. 3000-6500 prm. Gains of 30-35rwhp are common. Like 3.73 gear or better and 2800+ stall in auto's. MUST BE TUNED AFTER INSTALL. .560/.575 lift, 225/235 .050" duration, 108 LSA"

Thanks.
That is why i went with the VT's.Everywhere i read,and re searched,had dyno graphs to compare,and asked questions,the VT's seemed to be the proven ones without any other bolt on.Which is what i wanted.I wanted cams that actually made good power before any other mods were added(being a budget builder ),then those other mods would be the icing on the cake afterwards to further the gains.
My gains for torque was about 19 ft pounds.Before cams was 291.XX ft lbs,and after was around 310.XX ft lbs.
300 hp shouldn't be hard with what you are planning.I'm hoping to get close to that without the ported heads.I still need to put in my headers,and my ported Bullitt intake,then i will see how close i will be.I don't have full bolt ons right now either.
All i have for mods is the VT stage II n/a cams,mac h pipe & flowmaster 40's,ported stock upper plenum with an intake spacer & stock throttle body,drop in K&N,and a Custom Tuned SCT chip.No other hp making bolt ons.I'm quite confident that there is a few more ponies in her before i do anything else,but.... LOL!
I think once i get the headers,the Bullitt intake,added with a throttle body,and maybe some under drive pulleys,and another custome tune,300 hp should be doable.I hope LOL!!

Sounds like you'd hit atleast 300 with a half decent tune. I cant wait to pick up those cams next month. So far my favorite mod as been my short throw shifter best first purchase ever for us manual drivers!!! My buddy just finished rebuilding his engine over the winter holidays and he is gonna let me park my car in his garage and help me with my cams and heads, just gotta find a reliable engine shop to do the port job. Excited!!! Cant wait for that chucka sound!

The throttle body makes a cool like hiss sound between 2500-3000 rpm sounds neat. You got a nice ride though man. I like the no spoiler. I think i should take mine off i hate how the dust collects at the back around it

.Yes,the shifter,it should be the #1 to do on the list of mods.What an improvement it makes.
If you plan on the VT stage II n/a cams,you will not be disappointed,i promise
.To here what they sound like,click on "Listen Here!!!" in my signature.teeth: It's good to have friends that will help in modding,saves a ton. Make sure to get the pics,and up dates up during the process.

I'll most likely do a throttle body next year.I still need to spend some bucks for the Bullitt intake hardware before i can get it on
!! LOL!
