I have an 87 Z28 Originally with a 305 and 700R-4 , now it has a 355 built pretty wild and a 700R-4 Raptor Tranny, Id say pushing near 375-400, can you guys give me some tips on what I need in order to build up my stock 10 bolt that of which I belive to be a 2.73 limited slip but not really sure. Any info will be appreciated I need this thing to hold well cause im gonna run it on the street and strip with BFG Drag Radials that really hook! Any info on size gears to run and what to beef it up if any.

 

depending on how much street use it'll see and if it's your only car i'd go with at least 3:73s, i have 4:56s in mine. weld the axle tubes to the center section, use a girddle and braces, air bags, and LCA relocation brackets.
