I'm geting a sweet 302 EFI motor complete with all accs,wiring,computer. the motor is super low miles. Bighorn has given me some insight on what i might need. I will paste that here now... I plan to run the np435 with this as well. I have a 19gal fuel cell that will be in the bed. I guess i need to know just what all i will need for this swap.

Chuck,
If you're sticking with the EFI you'll need to use the stock TFI dizzy. It has a HEI stator incorporated in as well as the TFI which tells the coil when to fire. It's a 50 oz imbalance so you'll need a 50 oz imbalance flywheel. Most any manual 5.0 bronco or mustang would have it. I don't know to much about the 435 and the clutch but you'll have to make sure the bolt pattern for the clutch will work with that flywheel. Same SBF bolt pattern.
The harness is the most complicated part. The nice part about the factory EFI is that you hook all the sensors up, set the timing to 10 tdc and it does the rest of the tuning in the computer by learning your engine. Your sensors are a key component. If you're not sure about it working, replace it, as they generally are cheap and can really screw up the mix.
Here's some links to EFI swap in the Bronco......

If you are going carb you can use the DUI ignition. Remember it has a different firing order than an early 302...it uses the 351w order i beleive. I've got it written down but I can't remember.....I haven't gotten that far. You will have to change the drive gear on the dizzy to match the steel roller cam or it will eat the gear and trash the engine.
