I'm just trying to get clear on what I can keep and what I need to change. I have just installed a 49 state engine into a 94 CA f2. The CA and 49 state engines have very different cams. Can I keep the (CA)carbs that I have and if so what do I need to do to them?(besides block all the emission tubes) Also, can anyone confirm what CDI box is needed. Does the CDI have to match the cams or what?
