    Head swap worth 50 HP?

    What heads? What valve springs? You could be floating out you valves above 4600 if your spings aren't a high enough seat pressure with a cam that agressive.

    Replacing clutch and pilot bearing

    I agree I would replace the pilot bearing when doing the clutch, it is a major pain without a tool but one trick is if you can find a shaft the exact same size as the end of the input shaft you can pack the hole almost full of grease then pound on the shaft and the pilot bearing comes out from...

    spark plugs

    A dark rust color is not that bad to see I ran a car for years seeing nothing but dark rust colored plugs. It's a sign that you are running on the leaner side of things and need to be careful because too lean and you'll burn something up. You could richen the mixture a little and that will get...

    Cant figure out problem??? 87 5.0

    I'm gonna agree that you probably have a bad brake booster. I had one go bad in my 84' and just about killed the car every time I hit the brakes until I got home. Did you say you turned the fuel pressure down to 20psi? Stock is 37-39 and setting that as low as 20 would cause your injectors to...

    GT 40 P heads

    When you say TFS kit I was wondering which one you had. I see they have a kit for 110 lbs. and 0.542 total lift or a kit for 125 lbs. and 0.600 total lift.

    help removing cross-member

    Beat it too much and you might bend the metal hangar on the body, it's not real heavy duty. It might have corroded enough to fuse together. Your easiest course of action might be to use a cutoff wheel and cut both ends off of the bolt then get a used bolt from the junkyard or hardware store if...

    Fan + Underdrives = Overheat?

    Good point, I've had a run with pressure caps in the last three years I swear I've replaced half a dozen of them so I test every car I look at lately.

    Heat from tranny coming into car.

    Ok so it looks like he bastardized it. The right way to do it is to add the manual hump over the top and cut the origional hole bigger. I used the lower metal from the donor car as a template to cut out the hole, drilled out the spotwelds, marked the floor where the spot welds should line up...

    how much hp can you get out of this?

    Irreguardless of wall strength and other arguments some people don't think the 347 is as strong because it has been stroked out about as far as you can go and there are clearance problems to worry about etc. Also some people just like a motor with a shorter stroke especially if they are going...

    Fan + Underdrives = Overheat?

    Just because the thermostat looked good doesn't mean it was ok. You can test it by putting it into water on the stove and use something like a candy thermometer to check the temp it opens at. Bring it up to temp slowly and see if it opens completely before it gets to 190. If it doesn't throw...

    Heat from tranny coming into car.

    When he changed it from a automatic to a manual if he didn't cut out the origional hole and weld in the new hump that is for the manual transmission then the boot is probably unnaturally stretched and might leak air past it. You can tell pretty easy if you pull off the boot if the floor has...

    After TFS h/c/i swap, car runs rich + stalling...

    Is the performance good? Do you know what the fuel pressure is? I've seen major changes in performance based on fuel pressure and even though Ford's SVT teams opinion that fuel will not atomize properly below 40psi on injectors 24lbs and bigger is often argued in here I have multiple examples...

    Roll bar for a 1990 convertible??

    89stangwhiz do you have a picture of what the car looks like with it in? Side view etc?

    Photoshopped my car, please give me your thoughts.

    Looks good, I'd lean more towards a gunmetal though, it almost looks like there's a hint of green in what you have.

    After TFS h/c/i swap, car runs rich + stalling...

    +1 for overkill, you ALWAYS should go to the low side of what you need and use the fuel pressure to compensate. I know jrichker has a chart on what pressures you can run to get certain flow rates from your injectors and a smaller injector can flow more fuel than the next injector size up if you...

    Roll bar for a 1990 convertible??

    I was hoping for some input and pics from people who had them in their car so I could see what they look like. I already tried two big names and crapped out twice.

    Roll bar for a 1990 convertible??

    Yeah I'm a metal fabricator and I could build one but I don't have access to a nice mandrel bender and I want something that looks good in there. The car is in pretty good shape and after I finish some more chassis work she's gonna get some different skirts and a fresh color.

    Roll bar for a 1990 convertible??

    I'm looking for a good fitting, nice looking 4 point roll bar for my convertible. It's an 88' but the interior is converted to a 90' so I'm looking for something that works well with that. I bought a Hooker roll bar a few years ago and it would have fit the 88' not well but it would have fit...

    noisy T/O bearing?

    Yeah I had that with my last throw out. If I sat in any traffic I had to make sure to put it in neutral or else it would start making noise after a little while. It was more of a whirring than anything.
