WTB - Single Barrel Rochester Carbs
 
I am looking to rebuild my 250 and put an Offy intake on it so I am looking for three single barrel carbs. I am ok with them needing to be rebuilt but need to be useable.

Just a heads up ,You can't just bolt 3 stock carbs onto the manifold and expect it to work , You have to remove the choke plate and idle circuit on the front and rear carbs and add a progressive linkage , Only the center carb feeds the engine until about 20% throttle then the outer carbs start to kick in .check out Speedway motors and a uni-syn :chevy:

For years customers have been either putting up with poor idling multiple carburetor set-ups or spending hundreds of dollars converting the secondary carburetors so they did not have to idle circuits

Chrome is a little much for me but I did find the triple plain kit which is nice but expensive. Not to mention buying the adapters to bolt them to the Offy intake and then buying the linkage and the gauges to tune them. I mean its not a bad idea but it'll be over $1000 for that kind of setup.

Was the carb rebuilt?

It was a Holley reman about 8-9 years ago and it was on the running 250 in my truck until I pulled it and put in a 402 in 2015.

It has been stored in a climate controlled building since it was removed. It will run, but it may need rebuilt. It's a manual choke model.

I have a few stock parts and carbs on the shelf in my garage, I took it all off for a Clifford and a 4 barrel on my 250. Curious what advantages are to the three carb setup, besides being awesome. I have trouble tuning one carb let alone 3 :)
