Thanks for all the 66 block info, thee is a very high priced 66 Hemi block on ebay item # 150387073983. If I read the pad as you have decribed I believe it is a BH 426 with a 4-7-27 date. My cars SPD is 4-29-66 so this block would be correct for my car? please look at the ebay listing and give me your thoughts.
