a sm465 can be bought for around 100-200 bucks... rebuilt i think is around 400 but i cant really remember, and wife is pissed im not in bed.
700r4 are all over the place, and vary in price. best bet is finding a parts chevy truck for a few hundred bucks, take out the motor and trans, and sell it to the junkyard to get a little money back
