I thought i might add my 2 cents worth since i have a Yenko block , that one appears to be one of the marine blocks that everyone thought mine was . I dont have his picture in front of me but i dont recall it having a crest , i believe he also stated it had a marine cam and was a standard 427 bore. From all of the info i have found they were made in several different configurations ,Marine , Can-Am , Sprint , Drag Racing , Grand Prix ,and Stock Cars , some had steel liners others did not . Cubic inch ran from 427 to 498 .
