HP, so let me get this straight,since you spend so much time researching the cost to build one of these one of a kind marine motors,lets take it one step further, itemize the cost; A) parts B)machining C) assembly labor, and tell me which one in your opinion would be the largest of the three? almost forgot,include the last name of the engine builder as this will vary! just remember a merlin block is a merlin block!! a billet crank is a billet crank!!! carillo rods are carillo rods!!
