weight differential

[cryplydog]

Hello, can anyone tell me approximately the weight differential of the B-body factory D-60 4 .10 powerloc and a 8-3/4 powerloc and housing complete. Also the complete 23spline as opposed to the 18 spline 4-speed trans. This will my last go around with my old 64 440 or Polara and I don't see the need in all the weight any longer. I can weigh them but I don't need the exercise any longer. I already have light weight rotating assy, alum heads,intake,513 bell housing and getting Alum. trans cases. Thank you.

Approximately 60 lbs. The D60 is a more efficient rear end. The 4 gears are pretty much a wash. Kim
