340 block value?

Just some interesting info, when I built my stroker we sonic tested several 360 blocks and one 340. I had 3 72 360 blocks and 1 73 and all were different thickness. 2 of the 72 blocks were .135 or less on the trust side but the last one was over .200!, and the 73 360 was around .185. After seeing this we tested a std. bore 68 340 and believe it or not the thrust side was about .140. Like most things mopar I don't believe there is a any consistency to what years/ci blocks are thicker.
