Few Questions on drivetrain

I have the 8", not a real hi-po. but the motor is, IMO anyway, high performance. But im just wondering what cars came with 8" rear ends so when i go to pick and pull i know what vehicle to look into. a newer unit is 400-600 dollars, +200 for the gears, and for that price i could just buy a ford 9 with a posi already in it and then have it cut down and install it. and still save money.

What cars carried the AOD transmissions? and what is the, i guess, political name for them? this 3 speed auto is killing me. Id like to go with a t-5, just to get 5 gears. but id like a AOD better

Also, what all is involved in the swap from c-4 to a stock t-10? would i need a new bellhousing or adapter? or a new cross member? just wann amake shure i take the correct route.

Sorry, i ment the toploader 4 speed. thought that was the t-10. I can find the four speen and t-5's all day, but is the t-5 a hard swap? and the AOD from what ive heard is a no no on high hp builds. so that is outa the question. I love my c-4, but i really need more gears. im really wound out on the freeway as it is. When these 3.55's go in next week, she'll be screaming down the freeway.

Alrighty. Thanks. And anyone ever use the Yukon trak lock? i found one on ebay for 315 bucks. are they any good? i heard powertrax is the way to go, but for 315 the yukon interests me
