There was a good ad in mm&ff magazine about some company selling crate motors. It said something like "prices that will mkae your friends say what the f***" or something like that. The prices sounded good though.
I've never owned the crate motors, but I've read that the power levels can range from advertised, to way under. , I know that world products has those engines that can handle a good amt of power, but thought they were more than that. Myabe get a short block, put the rest together,
