Question weight comparison 9" vs 10bolt?

So after my first pass with my new ford 9" today i pull up on the scale and read 3120! My weight with the 10 bolt was 3080, plus on top of that i pulled out 50lbs! So from 3030 to 3120?!? Do ford 9" really weigh 90lbs more? It doesnt have an aluminum center section but jeez!

Even my 12-bolt was a lot heavier than my 10-bolt (I should have weighed them, but I was too lazy). I could pick up the 10-bolt by myself...I could barely budge the 12-bolt, and the 9" probably weighs even more.

It depends on the housing and options. Our MS housing is a few pounds heavire that the 10 bolt. Our CM housing is lighter than the 10 bolt. The Moser cast housing is a lot heavier than the 10 bolt.

The weight is at the right end of the car if that matters in the cost comparison. The 9" is also a lot stronger.

You need to make sure you eat lots of fiber and take a massive dump right before you head down the track. Most people overlook the dead weight inside their intestines.
