Does anyone know which carb and intake to get to swap a 2 barrel carb on my 76 Wag? It has the single barrel now and I would like to upgrade. The CJ 258 came with a 2 barrel, will that carb and intake interchange?

Thanks

If you dont have a problem spending a little money, I've been told that the best bet is the Weber Carb (about $450?). They make one for the 1 barrel manifolds & one for the 2 barrel manifolds. From what I hear even the 1 barrel Weber is better than the 2 barrel stock carb. I will be doing the conversion here shortly on my 258, so I'll let you know how it goes.

Go with the Weber Progressive 2 BBL I have been running one on my CJ! They are good carbs. We used to run em on VW's as well. I payed around $350 for mine less than a year ago new. Just shop the catalogs and find the cheapest prices.

Are ya'll saying to use the Weber in place of the factory 1bbl or on a 2bbl intake?

Do you really get more miles per gallon and more horsepower from the weber? Also they always have these on Ebay.

Another option: Find a newer two barrell intake off a 258. Then find a Rochester 2GC carb off a mid sixties Impala or comparable appliccation. A buddy actually picked a reman. carb up at one of the chain auto stores. Good carb and cheaper than the Weber...

Or adapt a Motorcraft 2100 series to the two barrell intake...

My 2 cents

Beware of the CarterBBD when grabbing a newer carb off of a 258. I've never been overly pleased with their performance.

You have quite a few ways to go with this.

Whatever you do I would lose the one barrel manifold.

1)the Weber good carb but expensive

2)get 2 barrel manifold and put the Rochester carb on it. I have experiance with these carbs and they are very good. You could pick one up cheap too.

3)get adapter and use a Motorcraft 2100 or similar Holley. These are good carbs also but some are too big for the 258 so make sure you get one thats in the 300 to lower 400 cfm's.

4)the most expensive is get a Clifford performance 4 barrel manifold. get the Holley 390 cfm carb and you would have a screamin 258! but this would cost $400-$500

Well I'm sure theres others but these are the most well know combos that can work easily.

Which Rochester carb is it? Model number? 2 barrel or 4 barrel?

Would a 2-barrel intake and carb from a CJ work? And if so, from which year? Just trying to get a little more performance from the 258, not trying to build a screamer. It has 4.09 gears and I only plan on running 33s, so lower rpm performance is key.

The Rochester carbs are 2G, 2GC, 2GV, 2GE could be missing some but thats the ones I know of. They are 2 barrel and can be found on many GM vehicles from the 60's-70's.

444, yes you can use the 2 barrel manifold. I would try to get one from before '80 because the ones afterward have alot of emissions fittings on them. I would avoid the stock carb on a CJ it is the Carter BBD. So pick up the 2 barrel manifold and a Rochester carb and bolt it all on. Will be very cheap.
