its funny how everyone seems to say blocks are cast. not all blocks are cast. merlin and Dart make forged blocks kids, not cast. and as funny as it seems, perhaps a block is far beyond his capabilities, altho completly reproducing engine parts for multi billion dollar investments in aviation isnt? hmm. i figured actuall block CAD prints wouldn't be accessable. and i am declaring i take this not personally, at all. The metal is called "hast X" thats the short hand for it. aside from that i'm not totally sure as to what it is. he said its what they use to weld with on afterburners and shite. heat tolerance seems more then enough for vehicular use. i have seen work that he and his "crew-be's" have done, they seem to have no problem making anything for parts. pistons, rods, remade a ford Z-tec head. said it wasnt that big of a deal. remember this isn't all by hand, its on a CNC machine, same thing "real companys" use. when did i say how long he was in? i mean someone made a comment about "2 years experience" blah blah blah. anyway, perhaps i'll just stick to "honda's brilliance" and get parts made for me. instead of entire sections. flywheel, pistons, crank, rods. etc. funny, everyone rants and raves about the metalergy of chromoly, why not use something stronger, lighter, and more heat resistant? here comes more bashing....blah blah blah. he's welded chromoly says its tough stuff, but this shit is way more hardcore. guess i'm sorta out in the open surrounded by fat kids in paintball tho, the object of critisism i am currently.
