Why? The EFI is a far more dependable and efficient system. Why would you want to take a step back and create more trouble than it's worth?

Posted on Jun 10, 2014

Testimonial: "It's already done and it is actually WAY simpler. Only thing I had to do way trace back my Water Temp and Oil Pressure wires and wire them back in. I was having many problems with the EFI and it would not have been cost efficient to fix it all. It is a performance motor with a Drag Cam, Stage 4 intake and so on and so forth. Being "far more dependable" I disagree. One sensor could go bad and it will no longer run. With a Carb you don't have that. Efficient, I also do not agree. If you know how to properly tune and work on a carb they are just as efficient. If not more. (Being efficient isn't a real worry for me either way) This way I can fix my truck on the trail without carrying a bunch of issues. (Diagnostic computer, Sensors, etc) For those out there that are wondering the same thing I was go with an HEI distributor very easy and saves a lot of time and stress."

You'll need to raise the engine to replace the oil pan. Take the trans./converter loose, remove the engine mounts, wiring, fuel line, and anything else that could be a problem with raising the engine. You can use 2 6 x 6's and place under the engine mounts and rest the engine on these. This should provide you with room to drop the pan.

SOURCE: need schematics for 1982 Ford with 351 engine

I worked at the library and you can go to the Reference section ( those books can't be checked out) but you can copy what you need, they have old repair manual that are extremely detailed at the professional level, pictures of schematics, complete brake down on repairs much better than you can find in any book today that you buy at the local auto parts store. if one library does not have them then go to the next library in your area.

SOURCE: Distributor Timing

With the Dura Spark II system, only an initial timing adjustment is possible. Ignition timing is not considered to be a part of tune-up or routine maintenance.
With the TFI-IV system no ignition timing adjustment is possible and none should be attempted.

  1. Locate the timing marks on the crankshaft pulley and the front of the engine.
  2. Clean the timing marks so that you can see them.
  3. Mark the timing marks with a piece of chalk or with paint. Color the mark on the scale that will indicate the correct timing when it is aligned with the mark on the pulley or the pointer. It is also helpful to mark the notch in the pulley or the tip of the pointer with a small dab of color.
  4. Attach a tachometer to the engine.
  5. Attach a timing light according to the manufacturer's instructions. If the timing light has three wires, one is attached to the No. 1 spark plug with an adapter. The other wires are connected to the battery. The red wire goes to the positive side of the battery and the black wire is connected to the negative terminal of the battery.
  6. Disconnect the vacuum line to the distributor at the distributor and plug the vacuum line. A golf tee does a fine job.
  7. Check to make sure that all of the wires clear the fan and then start the engine.
  8. Adjust the idle to the correct setting.
  9. Aim the timing light at the timing marks. if the marks that you put on the flywheel or pulley and the engine are aligned with the light flashes, the timing is correct. Turn off the engine and remove the tachometer and the timing light. If the mark are not in alignment, replace the ignition module.

If this doesn't help, please post again with the engine size because this will help us find all the specific info for you.

Should I rebuild my Ford Bronco 351 Windsor Holly 4 bbl carb or replace it with an Edelbrock carb?


In all my experience, if you know how to correctly tune a edelbrock then go with that, but, holley has outstanding carbs that can muster up to an output of 1,200hp. it would be much cheaper to et a rebuild kit from say, o'reillys, 20-45 dollars depending on which one you have.
I have a 1985 Bronco 351w 4x4, i just rebuilt my holley and she runs smooth
