Hey guys the G80 Gov-Bomb is done in my '8.5" 10 Bolt (donated from a '87 C10) under my 2wd K5 (specs in sig). I was already planning on replacing the 3.42 gears for 4.11 gears along with either a Yukon DuraGrip or Eaton TrueTrac and upgrading to Moser 30 spline axles. I was talking with an old buddy of mine and he is trying to talk me into buying a 9.5" 14 Bolt, then having the stock axles welded and redrilled for my 5x5" lug pattern.

I know guys with bone stock 10 bolt NBS trucks running 408 strokers and havent had any serious issues (yet).

If possible I'd prefer to keep the 10 bolt since I already have it and 9.5" 14 bolts run at least $350 around here with unknown gears and worn out G80's. Plus the aftermarket LSD's are more expensive than their 10 bolt counterparts.

This K5 is my weekend bruiser that has yet to hookup or seen a track. I do plan on making a few passes next Spring.

I am good with the upgraded 10 bolt or is it worth the added expense of going with a 9.5" 14 bolt?

Reasons and details would be great.

Thanks!!

the 8.5 corporate came stock in Grand Nationals and many cars run 9 & 10 seconds on them.

Maybe poke around over on turbobuick.com those guys have been putting great power down through 8.5's for over 25 years I bet they have a recipe to enhance its power holding.8.8", 9" , & 12 bolts are the popular rears here but only recently started seeing people mention using 8.5's so I dont know how many 8.5 experts are around here

Like mentioned above, 8.5" rears can handle some good power.
