fyi for anyone that runs or plans to use boss 302 blocks for there projects. ford racing is re making the 4 bolt main boss 302 block avaliable in mid 2006. screw in freeze plugs and everything. no price listed yet but it will be better than paying big bucks for a worn out original. part is listed in the 06 ford racing catalog. i would think the cost would be inbetween the 2 bolt sportsman block and the race blocks but who knows....
