If I am not mistaken the only difference is in the way they are cast. 706 uses a Semi Permanent Mold process and the 862 use a sand cast process. Its said that the SPM process is a little more precise. You can find a little more info in Will handzel's book "How to build High-Performance Chevy Ls1/Ls6 V-8s" Alot of detail and Backround on the Gen 3 Platform.
