'86 S10, MJ 2.8 engines

[jimoshel]

Are they the same? Have a 1986 MJ with a  2.8 motor and a bad carb. Auto parts store wants $450 for a new carb. WTH? Only paid $150 for the whole truck a couple years ago. The old carb is to damaged for a rebuild kit. Don't ask me how it got damaged.  I am thinking a 1986 S10 carb will be a direct replacement. and maybe the '84 and '85 carb. Anybody know ?

If the MJ carby is made by Rochester, then it should be thr exact same thing.

I have an 86 s-10 blazer it is TBI . 85 was the last year for a carb . As far as fitment , I don't know .

[jimoshel]

Just how hard , or what would it entail to swap to a TBI? Could I keep the same manifold? It's a good running engine so I really don't want to swap engines. Don't know squat about Chevy engines anymore.

Aftermarket TBI will cost you $2K.

 

Or you will have to get a stand alone GM ignition......I have no idea what GM used for CPS.

 

 

Weber carbs are $380 http://www.ebay.com/itm/like/201221464842?lpid=82

I've never had the two side by side , but Off the top of my head the harness, fuel pump, computer, sender and I believe the heads are different from carb to TBI , but that I'm not sure of . Seems like alot of work . Looking for a replacement carb or a intake that will take a a different carb would seem like a better option to me .

Sounds like the best option yet. Got a couple shelves full of carbs. Should be able to find one can make work. Won't be the first time I've taken a one inch piece of aluminum and made a carb adapter.

Your best option is to pick up a used carb from Ebay or elsewhere like THIS ONE and throw a kit on it.

Maybe a cc member has one . Maybe put a want ad?

Check the Rockman site and catalogue....they list the R22SE as a Rochester 2 bl carb used on both the S10 2.8 as well as the MJ 2.8

 

pull the carb and use the gasket as a template to you collection of carbs....one might match...... :thumbsup:

 

Right after I typed this...I thought of something....I had an 85 XJ wagoneer......I am positive it had a ford carb on the 2.8........ :dunno:

There is a kit out there to put the Holly Weber 2 bbl progressive carb (same as used on some Ford's) on the 2.8. Its a much better carb than the Rochester. Might be something for you to look up. I put a kit like that on my old FSJ Waggy 4.2 after its original carb fel apart. I've also used them on air cooled VW's a couple times.
