What is the deal with Gen 2 Hemi blocks?

its complicated ...even guys who have the money had a hard time to find one , some companies like muscle motors will make a new block, some are buying all aluminium blocks $$$$ , and some are lucky enough to buy crate motors or original 67-71 engines , personnaly i bought a siamese block last year , virgin block good for a 426-572 , but i paid a lot of money for it , engine is 75 complete and need installation and dyno+tuning gonna cost me easliy 20-25k , i have 15k in it right now
