Just seen this on hughes engines site,wonder if theres going to be an aluminum version also.http://www.hughesengines.com/TechArticles/smallblockfromritterracing.php
The only thing I dont like are the bosses for the head bolts that dont allow for a solid roller lifter. That should be an option. You can't make a block that indestructable and say "we wont make it to run a roller cam..." lol
