Which is better, Motorcraft 2100 or 2150?

Which is better, Motorcraft 2100 or 2150? I have the option to upgrade to a 2150 for $10, and I'm about to rebuild my 2100 anyway, so should I cough up the extra $10 and then just rebuild the 2150? I have read that the 2100 runs rich near open throttle.

If I get a 2150 from an auto trans 351, can I just swap out the linkage with my 2100?

Also, what do I do with the extra vacuum ports? Will simply putting a nipple plug on them still allow the carb to operate efficiently?

I have a stock '74 302 mtx.

The tag is: D6WE-EA

The 2150 was an upgrade for the 2100.

But if the 2100 isn't giving you troubles, I don't see the need to unless...

D6WE-EA no light truck application is listed with this ID number. Are you sure it's correct? If so, it may be off a car. D6 = 1976. Which should have been a 2150.

My 2100 is giving me trouble. It needs a rebuild. The idea is to upgrade to the 2150, then just rebuild that one, and sell my 2100 to make my money back (plus a little extra). I believe you that the 2150 came from a car, the guy never said what it was from. Can I swap the linkage though (atx linkage to mtx linkage)? The fact that it's from a car won't make it harder to swap, will it?

Edit: I just figured out 'W' means it's from a Cougar.

No, it won't. Not much was different over the years. Some had an altitude compensator, some had an electric idle solenoid.

It depends on the accelerator linkage. If it pulls backwards, you're good to go.

I believe (not sure) that manual transmissions don't need a linkage other than the accelerator.

Is this going in a 1974 F100 w/ a 302 and a manual trans? Can you post a pic of the 2150, or haven't you bought it yet?

No, I haven't bought it yet. I wanted to consult the panel first. I like to do my research.

It is going into my 1974 F100 w/ a 302 w/ a manual trans (3.03 ford). I've been so concentrated on tearing down for resto, I haven't gotten my engine's checkup yet, but I will rebuild as needed. After I do, I'm going for a nice crane cam and some headers to go with this new (used) carb. I also found out this 2150 I'm looking at has a 1.21 venturi, which I've also added that into the calculations. According to Crane's cam calculator, I'll be producing exactly what I want, a little over 200 HP, around 300 TQ, nothing killer, but not much expense for 80-100 HP and 70 ftlb TQ. My carb being 1.08 means it should sell nicely to the Jeep guys who want an upgrade. Everybody wins!

Thanks for your help Jermafenser!

It should bolt up no problems. Just make sure it's hooked up correctly.

The factory size was 1.08 for the 302. Bumping it to 1.21 will bring nice numbers.

Welcome.
