What kind of valve body/shift kit ro a 700r4

[erikrcks]

Buying my grandfathers truck soon and its a 93 z71 ex cab 4x4. Its got 60,000 original miles on it. I'm going to put a whole new top end kits from edelbrock (heads, lifters, cam, intake, and all gaskets.) its advertised to make just over 400 hp and trqu. i know this is a great tranny when built right. And was also curious about a converter too. And does the 3/4 tone rear end bolt on right in place of a 1/2 or are the spring perches farther apart?

Thansk in advance guys
