What is the maximum cfm carb that i could put on a 200? I have some birthday money and looking for a 2bbl carb to replace the 1bbl on right now.

 

Doesn't Holley make a nice 350cfm 2 barrel carb. If you had extractors/headers I would consider that.
As for the biggest carb, there is probably no real answer. I used to run an Australian 186cu inline 6
Holden HD with tripple 2" SU's. It used to haul *** and was very smooth throttle wise.

The other thing you might want to look at is the manifold. Will putting a two barrel carb on a
manifold designed for a single barrel offer any improvement? Maybe someone here with a 200
motor can answer that. I suspect though that replacing any original carb on a 40 year old car,
with a newer unit may improve it in some way.

I know a site that has a 1 to 2 barrel adaptor. Yes, holley does make a 350cfm 2bbl.
