Attention:  No two cast iron production blocks are the same!  Core shift during the casting process, variations in machining steps, machine tool wear, etcetera, result in all blocks being different.  Sometimes the difference may be substantial and these mods may render your cylinder block in need of repair or permanently damaged.  It is your responsibility to determine the suitability of these mods as being applied to your block.  We cannot and will not be liable for any damage brought onto an engine block or associated component resulting from these recommended block modifications.
Click on the link below to be taken to the High Flow Dynamics Technical Pages, which will open in a new window.  Once there, pages with various block mods will be available may be viewed, as well as engineering drawings and other useful technical information.
(The cylinder block mods listed in the High Flow Dynamics Technical Pages are not all inclusive for these engines but are specific modifications that are beneficial when executed in conjunction with the use of our products.)
