Kev I read somwhere that the tensil strength for the MR-1 block is 30,000. Was wondering if you know what the tensil strength is for the new allpontiac block? Also I have everything to build my 455.The pistons are .030.Will ALL of my parts go into the MR-1 block? Still trying to figure out which block to get. Thank you for your help Barry
