Anyone know the size of the injectors? If so what could they be replaced by? |

The stock injectors for the 3.7 are #53031099 24.0lb/hr @ 49psi. You can also replace them with FMS injectors, but you might need to get your computer flashed depending on what size you go with. |

FMS is Ford Motor Sports. I'm thinking about 24# @ 43.5 psi blue tops for the 4.6 Cobra to go with a ported set of heads with 206 cams and JBA headers. Added to my current setup, I think it could work rather well. I might have to get B&G to flash the PCM again though. You would want to talk to a mechanic first, but for a stock motor I would think something around a 21-22# since they are rated at 43.5 psi instead of 49 psi. If you're not doing something serious to get some more air through the throttle body, you don't need to upgrade the stock injectors. |

Obviously like your hood which probably provides a good amount of air to throttle body. |

Actually, something like what I just described above. The stock injectors are fine with my hood, and the hood makes a huge difference. The intake manifold seems to be ok while not running boost, and I already have a Fastman throttle body. Right now my bottlenecks are the heads and exhaust manifolds. Once I get them upgraded, and the bigger cams much more air from the ram-air is going to be able to make it through the system. |
