Ford 9 inch ?'s, POSI, GEARS..........
 

Hey guys what's up? I have a 1989 S-10 ex.cab. At this moment it is almost complete. The motor is a 383 with all the high dollar stuff(aluminum heads,forged Trick flow pistons etc..) with a lil over 500hp. It's got a roll cage, comming out of the lexan window, fuel cell, you guys get the picture? =P It's tubbed with M/T's that are 18.5 inches wide and 29 inches tall. It has a "BUILT" 700R4. My questions are, I need to decide on some gears, and we decided on 4:10's, but the guy at the shop suggested we think about it, since we are adding nitrous. Also a mini spool isn't really an option since I'm driving it on the street alot, and each of those tires are $200+. So I need a Posi-unit, I'm planning on ordering one from summit or Jegs, or wherever. I just need some opinions on the strongest parts, gear ratio, etc...This truck will see ALOT of strip time and alot of racing(of course), so any help is much much appreciated. Justin.
