Distributor option

[AzLizard]

I found a 2.8 distributor on ebay from Britain for a capri/cortina. It come with a powerspark electronic ignition(similar to pertronix) ,cap and rotor ready to drop in. Shipped,aprox $165.00 and made it in 4 days.

We finished the install today and it works. My truck has never idle smoother and it runs great.
We used the green wire from the stock coil to the module plug on factory distributor. Hooked distributor end to black wire out of new distributor and the coil end to the - on a msd blaster2 coil. Then cut the thicker red wire out of module plug and hooked it to the red wire out of distributor and the coil end to the + side of blaster coil.
I did have to change the plug wires. And i also installed a 2150 non feedbck carb

That’s awesome! It sounds like distributor supplies are drying up, glad you found another source!

Gets about same gas mileage with tfi module distributor physically advanced aprox 20deg, but throttle response is right now.and acceleration has improved triple.
Think I need to rejet the 2150,it's currently jetted for a 302. Hoping to improve mileage.
Anyone have any jetting that advice would be great.

 

[superds]

What jets are in the 2150 now? It’s been a few years but I believe you wanted it jetted in low 50s depending on altitude, temp, mods, etc.

Which 2150 do you have? The smaller ones have 1.08 on the side of the bowl, next bigger ones have 1.12 and the ones used on 2 barrel 429's flowed 500 cfm. Hopefully you have a 1.08.I would try dropping 3-4 jet sizes at a time until you narrow in on what the engine needs, then go 1 at a time.
Keep in mind though, while you're enjoying your newfound power and acceleration it's hurting mileage.

There’s also a 1.21 and is too large for a stock 2.8 (I know from personal experience as I had one I slapped on a 2.8 years ago and never could make it run well at low rpm).

I couldnt get one of those to run well on a 4.5. I changed to a 4 barrel holley from a 60s 289 and it fixed everything though


Why not run a weber 38?

Webers are expensive and you have to bone up on how to tune one. They are made to fit so many different engines, and they have tons of things you can fiddle with to tune it. Nice but complicated. Maybe China is making a knock-off weber, so maybe the price will come down.

I looked hard and finally found a china knock-off 2100 with 1.14 venturi in it. It ran fine on my converted 2.8, I got around 20mpg with it. But I could tell it did not have the throttle response at lower rpms that the original 1.08 venturi carb had. Very minor problem though. The plugs looked fine, I do not think you are going to fix anything with different jetting. The problem is too much airflow at lower rpms with the larger venturi. I have a manual transmission though, so all I had to do was upshift when putt putt ing through town.

Why not just put a vacuum gage and see what you are reading currently. Then you can adjust as needed?

I don't like the 2100 or 2150 carbs. I say throw it away and get something else

Wuuuut… best 2bbl carbs ever made IMO. Million different variants out there to get exactly what you need and dead simple to work on.

 

[superj]

Yes, are simple to work on and tons out there. I had about 10 and could't get any to run on my stroked i6. Thats why i dont like them. Webers ran in it and that old holley 4 barrel but no 2100 or 2150 would run properly.

But, tons of people do love them so they appear to be solid for most people

 

[Shran]

Weird. My buddy put one on a Toyota 20R… that was a cool setup. Lot of the rock crawler guys loved them before EFI was easy.

 

[superj]

Yup, same with jeep guys. A dude sold kits on jeepforums specifically to convert jeeps to motorcraft 2100/2150 carbs because people liked them so much.


Thats what killed me. Every person who never worked on a carb could get them to run and i couldn't, and i grew up working on carb'd cars

I had an Edelbrock performer carb on a 302 that was the bane of my existence. I even had a racecar buddy of mine come help me tune it. He got it running pretty good after just a few minutes with it but 6 months later, still frustrated with its off road performance, I took it off and replaced it with a 1.21 2150 (same one that ran like garbage on my 2.8) and the 302 ran pretty good with it.
