    I've been a member since 2005 but haven't really posted much.

    I finally decided to share some pics of the SLOOOOW progress on my 1980 Mustang Cobra. Picked her up a handful of years back and although she is currently in storage, I am busy juggling and engine build for her along with a '79 F150 restoration.

    A little info on the car. It is a 1980 Mustang that originally left the factory with a turbocharged 2.3L, 4spd, TRX suspension, sport steering wheel, Recaro buckets, factory louvers, no a/c or center console, and a lovely yellow hue.

    Currently she has a 302 backed by a C4 from the previous owner and quite a bit of damage from years of neglect and abuse. I am hoping to change that.

    Here are a few pics from when I picked her up:

    Here are a few minor things I have done to it as of late

    Refurbished the factory leather wrapped steering wheel with some new dye and center cap:

    [​IMG]

    New air dam from an 82 GT and an NOS fender I found at the local pick-n-pull:

    [​IMG]


    I also have some Marchal foglights and a new bracket to install and get pics of.

    This was done before I moved her to a storage unit to make room for another '79 parts truck. In the meantime I have been building up a '71 351C 4V engine for the ole gal.

    Specs:

    D0AE-J block .040 ob,
    KB177 hypertec +2cc pistons
    Stock rods w arp-bolts
    Stock crank 030/030
    Melling stock pressure oil pump w/High pressure spring
    Solid Bullet Race Cam
    FF280/371
    280/280
    251/251 @50
    619/619 lift
    108 lobe sep.
    Still Need a Double Roller Timing Chain and Johnson(Boss 351 style) metering lifters

    4V CC-heads w 2.19/1.71 Manleyvalves
    No port work
    Guideplates, 7/16-bolt
    Harland Sharp roller rockers



    Drilled and tapped for 4 bolt mains:

    Bottom End Assembled:

    Rear Sump Installed:

    Moroso Pan mocked up:

    I recently decided to go fuel injected on this engine and traded the Blue Thunder intake that I had for a Weiand Tunnel ram in order to modify it for fuel rails and an throttle body. I will post up pics as I progress on that project.

    Here is the toploader I scored on ebay:

    [​IMG]

    I plan to add a gear vendors unit and effectively have 8 gears to play with.

    More info and pics to follow as time and money allows. As I said I am currently working on my truck but I still find time to work on my stang every once in awhile.

    Post up and let me know what you guys and gals think!

    VERY cool.

    I know nothing about the ford 4 speeds. Are they pretty tough? When I hear top-loader, I think of the trans that went behind the 427 in an AC cobra. Same thing?

    Thanks!

    Indeed they are; they are still utilized in NASCAR albeit in a Jerico variant I believe (memory is a little foggy on this) and it is the same trans used behind the 427 although with a larger 1-3/8" input shaft and 31 spline output shaft.

    Some useless info on the toploader gleaned from Peterson's complete ford book:

    Hank Gregorich was the engineer interviewed for the article, he was the lead engineer of the transmission and chassis division at the time.

    Ford's testing of the toploader consisted of 50 cars each which were required to go thru 500 drag starts without a single malfunction . The drivers side stepped the clutch and powershifted into second gear as they ran three shifts around the clock until they were done .

    Check it out, new tunnel ram and throttle body showed up this past week:

    [​IMG]

    Had to set it on the engine just to see how it looks:

    Now the fun begins for designing a new upper plenum to attach the throttle body to.

    Where did you get the dye to redo the steering wheel? Was it rattle can?

    I used a black shoe polish paste and some elbow grease to shine it to perfection. Okay I'm lying to myself about the last part but it didn't turn out half bad considering it was terribly weathered. I did use rattle can on the spokes though.

    I love the style of the car, and can't wait to see the progress that you make with it!

    Engine on the carpet...That takes balls. I've had parts in the house before but never the whole motor or trans!

    Luckily I don't have to answer to a wife or girlfriend lol. It makes working on it in your spare time much easier with it in the house I find.

    Seeing as it has been damn near a year since I started this thread I figured I would post up a little more on the build. I picked up a thunder chicken 8.8 rear for the car over the long weekend to replace the aging 7.5 and I have started a search for some hydroboost components to provide some better stopping power with the new rear discs. I will go to five lug at some point in the future but for the time being the focus is on getting it road worthy to maintain some motivation with the project. Here is a pic of the rear end as she sits:

    [​IMG]


    No rear diff cover, but that just means I can justify one of these bad boys:
    [​IMG]

    Best part of all is I managed to score the rear end for $75 on Craigslist. Hopefully the next post won't be so long in the making.

    Cool! You definitly need a sn95 brake conversion of some sort because 13in rotors would look mean on that thing! Keep the pics coming. Where you located?

    I agree, they would look killer! I will have a few more pics to post up within the month as I plan on draggin' her out of storage. Location wise, I am in the sheep lover's paradise known as Montana.
