IMO the best is the MC2150 with the 1.08 venturi.
It has all of the benifits of not being a carter and if you do your own work much cheaper than a Weber. I can't think of any area where the Weber is better than the Motorcraft.

The MC carbs can handle some pretty good angles off road without fuel starvation, or flooding. Carbs are getting better, I have the holley TA 470 4 barrel on an offy intake. The TA series holley's are made for off road. It will take more angle than I feel comfortable with giving it, It makes my butt pucker and keeps digging. You can get a motorcraft carb at any boneyard, or there's a guy on ebay that sells them rebulit and set up for a direct bolt in on the 258. He also has an emissions version to get you by the sniffer if thats an issue in your area.

I went with the one from the guy on ebay (mc2150). It was more expensive than going to a salvage yard, but worth it for me. I have had zero problems now stalling at stop signs and it actually starts and runs great.

i was thinking of something with an airfilter that doesnt use the original airfilter housing but a more open air element like the edelbrock i saw that has the airfilter with a reusable element just sitting on top of the carb. figure i'll be able to pull more air and get some better gas mileage that way.

I have a Howell FI kit for sale. Clean running and great mileage. No carb tinkering needed. I have an aluminum intake with a new K&N sold with it. If you don't wanna go that route stick with the Motorcraft. Summit sells adapters to fit the Edelbrock on just about every carb.

This is the setup to run! I ran a MC2100 for 2 years and it was miles ahead of the Carter in terms of offroading. Once I got the thing dialed in it never stalled offroad and ran great on road. However, it is still a carb and it will need some tinkering with as the weather changes. I did end up with a Howell setup and I could not be happier. It did not add any horse power or MPGs over my well tuned MC2100. However, it did add better throttle response and a solid start and idle no matter the temp or conditions. Going on 2 years now and I have yet to touch anything.
