Maxxed, this is a fine, but I never argued with you about headers, in fact I backed you up.
Right on. I am there too. I chose to bore mine .030 over, since I wanted more cubic inches and better internals. At that time, there were more parts (high-performance) available for the .030 than the standard bore. I am currently building a 358cid R-block (302 .095-over) with 347 stroker crank and everything I can throw at it. It will produce (hopefully) 750rwhp when I'm done. Watch for articles on this site coming soon in the technical section!

1992 LX, thanks to Chicane Sport Tuning and some friends.. it is now wrapped with new graphics and ready to hit the streets AGAIN!!!!
New at this fellows, and gals. Just bought an 89 lx 5.0 it has 3.73/cam/flowmasters/fordmotorsport headers.
I'm unsure of what type of cam, but I've been told it's small. Anyone care to help estimate the current ponies on this puppy? Oh yeah it's a 5 speed.
dude;headers are not a peace of mind unless you agree that they allow the engine to breathe better,increase performance and add torque(when installed with the correct diameter pipe sizes).to say that just adding cat-back exhaust will suffice contradicts your statement that headers dont make a difference.
if you dont believe headers make a difference,why change your mufflers?unless your just into sound.the improvement your gonna get from just mufflers is minimal compared to the improvement you get from a good set of headers.the bottom line is all exhaust components work together. headers, h- pipes and good quality mufflers is whats going to allow for increased power,fuel efficiency,cooler running engines and overall performance not to mention the importance of pipe diameter size(depending on the application).do you just change a throttle body and not ever change the stock intake ? you will see some improvement but its quite minimal until you change that intake.dude theres nothing more important than induction and exhaust,they both work together so if your working on exhaust dont half stepit,that cam that intake that throttle body that air meter that set of heads that hard earned money is all worth nothing if all your motor can do is inhale and not exhale.the purchase of a good set of headers is always money well spent.
I have cat-backs to better evacuate the exhaust. I was trying to make the point that to add real power as it relates to air, cat-backs/headers are the way to go, but dont be under the illusion that headers produce noticeable power gains without dealing with the heads first. If I were to do it all over, I would have had the heads ported first then the headers then the exhaust. Sometimes money dictates what gets done first.
If you want to change your cam which is a good choice, it will add hp and torque but it is best to change heads, intake, mass air meter, throttle body, injectors if your going to get more fuel you need more air.
If you bolt a set of long tube headers on a bone stock motor you will notice a hp increase, it wont produce as much hp at the wheels if you dont chang the heads and rest of exhaust, but you def. notice a difference when driving. My shop has done tests by bolting on one bolt on at a time to a stock motor testing it then taking it off and putting another bolt-on on. Long tube headers are very noticeable. A cat back adds little hp and almost no noticeability with everything else stock. Alls it does is add sound.
I have a 95 Cobra. It has the stock Cobra intake and GT-40 Heads. I'm looking to change the cam to a ford racing cam, either E303 or B303. If i put in a new cam, i shouldn't have to upgrade the heads or intake right? Also the Cobra has 1.7 rockers. Will i have to change to 1.6 rockers with these cams? I know i will have to get new springs and rods. I just got done tunning the car with new sparkplugs, msd wires, cap, rotor, blastercoil, and a few other things. Also the car has Mac equal length headers, Bassani off road x-pipe, Borla catbacks, and a BBK CAI. I'm looking to get a BBK 70 Throttle body and a Pro-M 75mm MAF. I guess the question is, do i really need to upgrade the intake and heads, and what would be better if it's even worth it.

I've owned a few stangs over the years,i recently picked up a 84 vert with 56k original miles on it.I have everything ready to go for the 5.0 transplant when someone tells me that it has a different k-member than the 4 cyl. and the 5.0. Is this true,i've done plenty of 4 to 8 swaps but never ran into a v-6 swap!
thanks

if you have a 95 cobra im pretty sure the specs on the current cam are the same as a E303. you might want to make sure of that before you go spending money.
you can use 1.7 rockers with the E303, (i have the crane 2040, which is the same cam, with 1.7 rockers ) and no you dont have to change the heads or intake.
I'm 16 and got a 1989 5.0 Convertible...most excited a 16 year old can be. :thumbsup It has 193,000+ miles so I'm kinda hesitant on modifying it. But if I do, what sort of engine modifications could I make in the driveway with only a set of jack stands and basic tools that isn't too complicated? I want to take it as far as I can just in the driveway. Would it be too much trouble bolting on some new heads, or upper/lower intake manifolds? How hard is the exhaust to replace with only jack stands?
I may be young, but like to think I know a lot for my age. Haha...but I know the horsepower isn't just adding all the modification increases, but I've been wondering, in general, would the end horsepower be greater or less than adding the horsepower increase from each part?
be real careful when you doing any modifications on a motor with that many miles, cause at that many miles with a horsepower increase the motor may not be able to handle the added horsepower increase also unless you have some experience under your belt be careful trying to replace the heads intake and so on it can be done in a drive way on jackstands but you may take a bite out of more than you bargained for, i know a little bit bout cars and so on but i would not go tearing into my mustangs heads and intake with out some help one small mistake and it could be get pretty mess, just some helpful advice from a fellow mustang owner
all i have to say its not cheap to do any thing the only way you save money is if you can almost do every thing yourself, but if you are going to leave a stock bottom1/2 and do every thing from cam to cold air intake and not do any labor price it all out the price a crate motor with 345 hp sometimes it is less to get the crate motor realy look into it keep on dragging

what are the ness. supporting mods for supercharing? I don't want to mess around with the NA stuff if I buy a stang. I assume, full exhaust, does the head and cam need to be replaced also? Clutch? You guys are talking about replacing the gear? In the tranny?
