    question about rims

    Stock backspacing on what wheel? Answer to your question is it'll stick out 3/4" farther if the wheel is other wise the same width. Spindles come in several variaties..... '79-'86 spindles were all pretty much the same. '87-'93 V8 spindles are different than the non-V8 spindles (which are...

    5 lug conversion with 96+ spindles

    Adding width to run 4.5" backspace wheels will push the wheels further out. Making fitment worse. The '96-'04 spindles are 8mm wider per side. I assume this is connected to your other post? You would have to remove track width to install wheels with 4.5" of backspace. Rear axles vary...

    question about rims

    Yup. 5"-5.5" of backspace is correct on a 8" wheel.

    7up identification/Modify, or not?

    The 7-Up cars were just a trim special package. On there best day they may be worth maybe 10% more to some people. I wouldn't pay more for one, in fact I'd pay less. Ford got stuck with them after 7-Up backed out of a deal with them to give them away. So Ford had these cars to dump...

    What are the stock cam @.050 specs?

    As he was saying, the only way to really know is to measure the specs. Ford's QC was pretty relaxed with respect to lift's and durations. But what he said is pretty much correct. OEM cams are made as cheap as possible so QC is not what it could be.

    How hard to get 400 rwhp out of street 351w?

    Ohhhhh.....well that makes sense. I was figuring you were starting from scratch and building a shortblock. If I could pull it off I'd like to put a 408 in my convertible. But I pretty much know that's not gonna happen. I'm losing interest in Mustangs lately. Getting boring to me.

    autometer gauge would this work?

    Not without a mechanical drive distributor. They're very accurate though. You can upgrade your distributor or get a different tach. I don't know if mech drive is compatibale with EFI. I don't think it is. If you aren't EFI it doesn't matter.

    Sounds like you have a mechanical drive tach.

    How hard to get 400 rwhp out of street 351w?

    I think your list will get you REALLY close, and maybe get more than the number you want. 10:1 compression for sure. I have a question though why non-stroker? Only reason I ask is my brother built a stroker 418 for his Ranger and the 418 rotating assembly is somewhere around 23lbs...

    mild detonation... with 87 octane and 10deg advance???

    Without O2 sensors your computer is guessing at what ammount of fuel to use to get the correct A/F ratio. Combine that with any other sensors or systems not working 100% plus any mods you've made and it all adds up to poor performance and the detonotation you are fighting.

    mild detonation... with 87 octane and 10deg advance???

    When were the O2 sensors replaced last? They can contribute to this kind of problem too.

    88 speed density cam specs?

    There are 2 specs. The one Ford spec'd cams to be at that time and whatt hey actually spec'd out at. They can be quite different. Which explains why some cars are strong runners and some feel like turds. Tmoss posted a chart once with the offical specs. I saved it and can email to you if...

    B.S. on gear install

    Most shops in my area won't even install parts you don't by from them. And the one's that do, charge at least 50% more in labor.

    150lbs of weight reduction

    Rear seats are worth about 50-60 lbs. Is your spare tire and jack out? If not, get them out. They're heavy. Do you have light weight wheels (ie draglites, etc...)? If you replace the OEM driver and passenger seat with an aftermarket seat you could save 25-30 pounds each at least. Factory...

    Went to the Dyno Today

    :rlaugh: Those numbers don't seem too bad to me. Though I would expect more hp too. Torque looks real good though. How far to a Dyno Jet dyno?

    5.4 DOHC 96GT Project

    Building big power Modulars seems to = expensive. But it will be cool if you do it. I don't suspect I'll ever build a modular engine up. The cost vs reward factored with emissions concerns for cars with mod motors just isn't good. Not even close for me anyway. I love my '98 4.6 SOHC GT...

    Requirements for Kenne bell supercharger, help!!

    You can only buy KB blowers from Kenne Bell direct or from a shop that is part of their dealer net work. Period. They do not do internet 3rd party sales. And will terminate dealer status if a company does it. You won't need any upgradeis you are doing the 6psi kit.
