    Need to build rear end....need laymens terms

    The rear axle upgrade is worth every penny, I understand how most on here will say that 3.55-3.73 gears are what you should run, Ive been there and tried them, but my car is way faster even while spinning a 315 radial with the 4.10' and now the 4.30's. You may wanna go with the 4.10 gears utill...

    Need to build rear end....need laymens terms

    2003gt, your engine/exhaust setup is basicly the same as on my 99, the power is a bit off, maybe you dont have a bullit intake. Anyways, I have had good luck with my "stock" 03 cobra posi, superior axles, and 4.30 motorsport gears. I run only on MT tires on the street so I dont have much of a...

    Bought a 4V motor for 60$!!! LOOK!

    Good buy, 60 bucks is hella a cheap. Those heads wont change the compression too much on a non-pi 4.6 too make a differnce. You may get by with a 99+ cobra intake and headers and you will need the front cover and maybe chains and guides. you may be able to cover most the cost by selling what you...

    Early narrow bolt pattern tranny to 302?

    two problems with that, the trans bolt pattern isnt the same and the register on the input shaft retainer is smaller. A later stlye retainer can be swapped on the t-10 and toploaders and then you can use a scatter sheild which has both bolt patterns. You can also try and modify a cast iron...

    Rear Gear Recommendations

    3.93's? You will notice the posi even more with the gears. better to spin both tire than just one. And even a bigger kick when the t-5 goes in. 2.75's are good for salt flat race cars not street cars.

    Header Testimonials....Header Chart??

    Ive talked to both RCI and Accufab about headers for my 65. Im goin with RCI since they seem to understand about my specific needs. 1 3/4 long tubes that they claim wont hang as low as hookers but must use the 66 newer engine mounts and brackets. My headers are getting a special bend at the head...

    Rear Gear Recommendations

    3.89's will work great all around with your planned engine combo and t-5 swap. And for sure a posi, best to get the stronger four pin posi for the best traction.

    Popping noise out of newly installed rearend

    Get a bottle of XL-3 from ford, if that doesnt work then you have bigger problems. But it does sound like you have clutch pack chatter.

    Rebuilding 289... please advise on manifold/carb/cam

    goin to a stock lookin four barrel setup wont give you the fun you deserve. Go with a performer rpm/ sealth manifold, 280 comp cam and lifters and a holley 600-650 mechanical carb. headers will help but for sure good mufflers and 2.5 inch pipes

    Rear Gear Recommendations

    with the comp cam and afr's go with the 3.70-3.89 and a looser converter for street driving. 4.11's and converter for more street strip.

    RIP engine? need some good tech.

    sounds like timing or ignition, unless you pulled a few rocker arm studs but that usaully makes some noise. Compression test first. 13/16 spark plug socket to remove all the plugs.

    5.4l heads on 4.6l

    lightning heads are a windsor PI head. they are the same as the 99-00 mustang gt heads and will fit the 4.6 blocks and PI intakes, certain parts will need to be changed if you are starting with a romeo 4.6. Best 2V head casting out right now is the 04 romeo PI head.

    02 GT Vortech SQ 14# vs KB 14# Dyno's

    D1sc at 14psi would get you over 500rwhp, you must have a built engine.

    02 GT Vortech SQ 14# vs KB 14# Dyno's

    Good comparison, we know who won the dyno race but what about the 1/4 mile. My money is on the centrifugal cars.

    louder pro chamber??

    Haha, I usually say the same thing. I love the quietness of my 99 and the fact that it runs good without being loud.

    3.73 gears or 4.10 with a SC car?

    if you have the cash for a supercharger/gears and want to go to the track then you should have no problem buying a pair of slicks to fix your traction problems. why would you add 100-200 more HP just to bog it down with 3.55 or 3.73's. gears dont help traction, tires help traction.

    4.6L SOHC stock rod help

    louder pro chamber??

    Im sure if you replaced your setup wth a 3 inch prochamber and mufflers you will get the sound you want but will hurt performance. Or maybe remove the tail pipes and go with turn down tips off the mufflers, will make the car sound louder on the inside but not really make much a difference on the...
