MC2150 Needed

The Boss and I will be making a trip to Colorado soon. I suspect that the Carter YF is going to have big trouble at the higher altitudes and think this may be the time to put on a Motorcraft 2150 for the altitude correction. I've looked for one around here to no avail. Even the vanilla 2100s are scarce, and the 2150s probably were never offered at 300 feet above sea level. There are plenty on E-Bay and Craig's list, many supposedly set up for a 258, and some apparently from commercial vendors. Does anyone here have any experience with any of the vendors offering them? If I got one with worn out throttle bores and incorrect jets I could fix it, but would pay extra for one that I wouldn't have to mess with. As it is I'll have to modify the intake for the two-barrel and that's enough trouble.

I am really not wild about going to a throttle body FI. If Megasquirt built a kit for a mass airflow sensor I'd probably jump on it. Anything less seems like a half step. I can do a 2150 now and wait.

EVERYTHING's easy for the guy who doesn't have to do it.

But even a MAP system is better than the Holley I have.

Only if keeping that 80 year technology (the carb) is a whole step!

My (MAP equipped) TBI hasn't and likely won't see anything more than the 2200'ish we have here in the mountains, but it sure does run good between here & there!

IMO, the differences between MAP & MAF are negligible... where just doing fuel & not controlling the timing leaves a BUNCH on the table

2150

How soon? I will check next week if you can wait that long. I have a guy that offered me 3 this winter. He wants to stay on my good side. I was going to use them for spares but I will grab you one. I swapped mine out last fall and it is much better. Also when are you coming through the county next? I have a care package for you. Do you still have my cell number?

A grandson is graduating from high school in Centralia soon. We'll be there then if not before. I think I lost your phone number, but mine is on my website. Give me a jingle some time. Thanks!

Ok Jim, Of the 4 I got from the guy today, 1 is missing some parts, 1 has a 1.28 venturi (to big) The other 2 are the desired 1.08 venturi and look good on the inside. They're yours if you want them. PM sent with my number. Oh, I really think you would be ahead of the game to find a 2 BBL intake to make this work well. Just an opinion.

Thanks! I'm pretty much over my nasty cold and can come pick them up in the next day or two.

The likelihood of finding a two-barrel manifold that will match my exhaust manifold is pretty slim. I think that when they went to two-barrel carbs on the CJs they also tilted the outlet of the exhaust to the rear,. Mine dumps straight down, and I don't want to make a new exhaust pipe. No big deal to cut the top off and weld on the proper mounting plate for the MC.

Do you know what either of the 1.08s came off of, or does either still have the brass ID tag? My parts guy says that it will make it a lot easier to get the right kit.

I will be around tomorrow but I am leaving just before noon on Friday with my youngest son on a youth turkey hunting trip. Both carbs have the tags installed for your convenience.

Terrific! I should be there some time late morning. I'll call when I get close.
