The intake for a CCC will only bolt to the front half of a CCC engine. Those extra carbs can add as much as 500 rpm (thats a whole lot with a 28-32in. prop). Those lightweight flywheels are a hard find, I just got an original aluminum OMC racing flywheel(from a CCC engine) this summer. You really need one if you are turning those higher rpms (apparently these motors can reach 8000 if set up right). I have seen the cranks break just above the top bearing. You should be able to find a used one for around $300-$500, I don't know if that is too much and I may know where one is. The way I look at it if I can find a crossflow for a few hundred dollars and put a few hundred more into it to make it perfect I'm way ahead of the game. I like them because they are so easy to work on. Good to talk to you.
