350 stock 2 barrel to 4 barrel conversion
 

Hi guys just curious. What would be involved besides swapping the intake on a 2 barrel to 4 barrel carb swap?

Hi There..... as long as the 4 BBL intake you want to use is from the same "era".... no problem. They early intakes had the oil fill tube on the intake, later had on the valve cover. I don't think you will be happy putting the 4 BBL on a 2 BBL engine. The 4 BBL engines don't only have the carb, but have heads and camshaft to handle the extra fuel, and create more power.

As above but you may need a new air cleaner as well. When I did this on a 79 camaro years ago, 4bbl air cleaners could be had for a trip to the junk yard and a few cents. Now, they are a bit hard to find. Or in my case, borrowed from a dead 68 Impala along with the intake manifold.

If you haven't bought the carb yet, and you're going to make this swap, get the carb with the smallest cfm rating---- it will work a lot better with your engine.
Large flowing carbs usually won't do well on stock or mildly modified engines because the engine won't draw enough air through the carb to get a proper air/fuel ratio.

After reading the responses. I might just stick with the 2 barrel
