305 v6 questions
Does anyone know if the carb and water pump on a 305 v6 are engine specific or if other engines ran those same parts. The carb is a 2 barrel and I'm trying to find a rebuild kit for it and the water pumps broke. Any help would be greatly appreciated.

Re: 305 v6 questions
You'll need the numbers off your carb. to get a kit for it. I don't know what kind of carbs. they ran on those things, but I would think most any 2 barrell would bolt on to your intake if you can't find a kit. I would think the water pump would be GMC 305 V-6 eng. speciffic, but I could be wrong. You'll just have to have a parts guy look it up. You could punch it in to O'Reily's or RockAuto.

Re: 305 v6 questions
I got the water pump for my brother's 305e from rock auto. It was a perfect match. Be careful when going to your local auto parts. I work for Advance Auto and our computer often confuses the 305 V6 with a sbc. Don't be afraid to get parts from your flaps but you might want to go in and ask if anyone has experience with old GM products.

Re: 305 v6 questions
The water pumps are still available no problem. The larger V-6's used a water pump with a threaded shaft, just be sure you get the one with the flange for the pulley. The original carburetor should be a Stromberg WW. Those are pretty rare, but a Rochester 2 bbl. off a older small block Chevy would probably work O.K..
