    I'm in over my head and punching above my weight, so if anyone can help me it would be great.

    I thinking about a v8 conversion i have the possibility on an engine and box but will a C6 transmission fit my 70 maverick? Or am I being stupid.

    thanks

    The c-4 will fit a lot easier. The 70's tranny tunnel is a bit narrower that year. Also the c-4 takes less HP to run.:)

    anything is possible, but most likely you'll have to cut the tunnel and make it larger for the C6

    At minimum you will have to fab up a custom crossmember and will have to shorten the driveshaft. These mods would be needed on any Maverick. The 70 has a smaller trans tunnel, so even if the C6 fits later Mavs, it likely won't fit the 70 without customizing the floor pan.

    What headaches with a C4? depending on application from stock to fully modified they are a bolt in.

    Sorta on topic...what is the advantage or difference in running C6 and C4?

    All I hear is C6 is heavier, bigger, and parasites off more HP. What else? Still a 3 speed, right? So what is the difference?

    It is bigger - everywhere than the C4.
    In stock form it can easily take 450-500 HP.
    The gear ratios are the same.
    It doesn't fit in many of the smaller Fords of the era.

    C-4's don't handle torque like a C-6 does. Nor do they like to be neglected over the years. ;) With a C-4 , you "use it or lose it". But in also using it, it's life span is also shorter than a C-6. Sure the C-6 uses more power, but once it's in there, you can forget about it.

    Devil's advocate here...but wouldn't a decently built C4 outlast a C6?

    But, I guess you can build a C6 decently, but with our smallblocks, it seems that a lighter stronger built C4 would still beat out a C6 after calculating weight and size...

    Unless I am missing something.

    No. I've had two vehicles with C-4's. Both have had numerous rebuilds. I've had two other vehicles with C-6's. Neither ever had to be rebuilt. One was 38 years old without a rebuild.

    Is the C6 a newer model, or just the "truck" model of the same years?

    I mean were the 4 and 6 made at the same time and the 6 got put behind bigger cars and trucks while the 4 got put in the smaller ones, or was the C4 THE transmission for certain years and then the C6 came along to replace it...

    Sorry so many questions. I just never before got an opportunity to learn this stuff.
