I have a 1985 Ford ranger v6 2.8 litre w a 2 barrel carb. Can I put a 4 barrel on it with an adapter plate.

 

[Dirtman]

Why....

 

[sheep herder]

Probably but why would you want a 4 barrel on a 2.8?

 

[Barbara]

More power

Dont fall into the trap of over carburation.

No a 650edelbrock on a stock 2.8 wont make it run like a big block.

Assuming yours is still running the stock feedback stuff you wont be able to really do the swap anyways, unless you changed the ignition system.

Ignition is changed to duraspark

You might do ok with a very small CFM 4bbl....like a holley 390. But honestly a good 2150 2bbl should flow just fine to maximize a stock 2.8s potential.

I was going to rebuild the carb but decided to buy one instead. Before I do I was thinking about getting a 4 barrel

 

[Barbara]

Ok that sounds good. I will stick w the 2 barrel ty very much

UK efi conversion is much more better.

The stock 2.8l engine uses 275cfm of air at 5,500rpm

So any carb that can provide that air flow would be fine to use, so a 2-barrel is fine, most are 300-350cfm

A standard 600cfm or 700cfm 4-barrel has 300-350cfm primaries and then 300-350cfm secondaries
So would also be fine to use but would need a bit more tuning so secondaries wouldn't flood out the engine when you floored it
There would be no power gain since the 350cfm 2-barrel has enough flow for the 2.8l at max cfm, I wouldn't recommend RPMs above 6,000 on the 2.8l as is

There are some 390cfm 4-barrel carbs so smaller primaries which would give better MPG driving around town under 1/2 throttle or so, and wouldn't flood out the engine at full throttle if adjusted correctly

The stock Ford 302/5.0l V8 needs about 430cfm at 5,000rpm, so a 4-barrel would be better

So its all about the CFM of the engine when picking a carb

I used an Offenhauser dual port manifold and a 390 cfm Holley on the 2.8 I put in my friend's Sunbeam Alpine. It worked great but the manifold is real expensive unless you stumble onto one at a swap meet like I did. The 2150 2 barrel off a V8 will give you more CFM cheaper. Make sure not to get a carb from a 429 2 barrel, those flowed 500 CFM and would be too big for a 2.8. You can get a boost in power by tweaking the centrifugal advance in the distributor to get it all in by 2800-3000 rpms, usually without buying anything.

Holley makes a 500 CFM 2bbl that is a direct replacement for the 2150...

Still way to much carb for a 2.8.

Too bad they don't make headers anymore for the 2.8. Those manifolds and downpipes are pretty dinky compared to a 2.9 factory setup. Can't get the air/fuel to go in if you can't get it out also.
