how do i convert from TFI ignition to points???

hi.
i just purchased a 84 bronco 4x4..300 inline6...it has the TFI dist.--unfortunately..it has been hacked up..the wiring sliced and diced...the motor and body are great!!!..but..it runs slugishly and gets hot because the TFI is not advancing the timing...SOOOOO....
what i need is advice on converting it to a points dist..doing away with the electronic and other connected stuff...can i get some help..possibly a wiring diagram???HELP!!!..thanks

Ouch, sounds like something else in your computer is sending wrong info to the distributor. Will points work with your present computer? Points are not the way to go...you want to at least use a magnetic triggered distributor that has a stator and reluctor rather than points. MSD is a bit pricey, but they have some awesome distributor hookups.

Good luck,

'82 F150 2WD w/351W (orig 300 I6)

[font size="1" color="#FF0000"]LAST EDITED ON 17-Aug-00 AT 11:28 PM (EST)[/font][p] Im not totaly sure but i dont think a 84 had a computer beyond the ignition control module. Id hardly call that a computer tho. If i were you i would rewire the original system it real is a good setup. But if you want to run points all you need is a ignition key switched hot wire running to the positive side of the coil with a ballast resister inline and the wire from the points distributer hooked up to the negative side of the coil. Thats it its that simple....
My Gremlin had points once apon a time. I have since converted it to the same exact ignition as my 85 E150. runns much better and i dont have to change points ever. Im looking to do the swap on my F250 also but just havent gotten around to it yet.
fer what its worth

hey thanks all...
i did the points conversion...1971 f150 points dist...only 39.99$...accel coil...used the hot wire off the stock coil....carb had good vac line for advance...set it at 8 btdc timing...dwell at 37 deg..plugs at 35....cut all wires to carb but auto choke....everything is VERY SMOOTH and running great!!!
cruise control still works perfect...getting better gas milage....

i know most say electronic is best...but..when it breaks--points are easy and cheap...can be filed clean on a match book in the woods..ect ect..

you can have the electronic crap....ill take the points and old fashioned way...couple wrenches..no puter needed...no great expense needed to fix things...
my 67 chevy..and 70 triumph both have always had points...change them once a year..never a prob...and the tuneup parts r much cheaper and the system easy to trouble shoot...
thanks all....

I actualy agree with ya on points being better. When i drive my Gremlin cross country i throw the points distributer in the back just in case.I had a 92 Crwn Vic i sold it because i didnt trust it out in the middle of nowhere. Not because it was unreliable but because it would be impossible to rig on the side of the road if something did go wrong.I trust my old cars alot more anyways.
I run the electronic in the Gremlin because i get a hotter spark and better gas mileage. Later im going to hook up an MSD box to the distributer and do away with the ford 'blue tab' controler. This is my daily driver so gas mileage is a big worry.
This was kinda offtopic but.....

Does the 300 have the EEC-IV crap along with the TFI like my 84 2.8?

Duraspark is probably one of the best electronic ignitions ever made for factory ##### and as far as not trusting it just carry a spare brain box under the seat

While points are simple they are sensitive to humidity and wear. The Duraspark setup is cheap, easy to troubleshoot, and if ya put a stand-alone harness (to avoid having to dig into the firewall area to troubleshoot) effortless to maintain even on the hideous beaters I drive.
http://www.trailhed.com/images/DuraSpar2.jpg is an excellent diagram that works for either conventional or TFI Duraspark engines, and grounding the black wire directly as he does is a good thing.

My apologies for posting the above diagram instead of the link to www.trailhed.com from whence it came! I stepped out for a bit and could not edit the post. They are a Jeep site but the wiring is the same.

I have a few questions about the TFI to Duraspark II conversion that the diagram above brought up. Where is the resister at in the harness on an early 70's 351W? Which would be better to use, the TFI coil, or the oilcan coil mounted on the engine?


88 F-150 4X4 XLT Lariat w/5.0 EFI 5 spd (DAILY DRIVER)
86 Ranger 2WD w/2.3L EFI 5 spd to be 351W 4bbl C4 (NEW TOY- DETAILS WHEN FINISHED)
85 Old Cutlass Supreme 350/TH350 Holley 4160,Edelbrock Performer intake, el-cheapo headers, High Energy Cam 270H series cam, 15.588 best 1/4 mile with original 10 bolt 2.41 gears (OLD TOY)
