Nice diatribe. Reminds me of one of my favorite sayings. "People that don't get it, don't get that they don't get it."to much $$$$$$ for a hot rodder or racer concidering the cheap Cat caps that it appears most are using when doing a 4 blt conversion on a Dove-A block , i mean $50.00 bucks ,,maybe worth the $$$$650.00 to guy restoring a Boss-9 mustang that had a block w/ no caps??? the No. 1 cap would be a nice addition to my Dove-A factory 4 blt block , but it would add very little strength to the bottem end at a high cost. cost vs. effectiveness, so, you may be holding them for quite a while at that price until a restorer of a boss9 needs them for a restoration.
