Thanx to everyone, your help as always is greatly appreciated.
I was talking to my neighbor who has a 65 c-10 with a 230 L-6. He went in to the same a***zone and told them he wanted a rebuilt one-barrel carb and they tried to sell him the 800 cfm to 1250cfm carbs also. He explained that the manifold would not hold a four-barrel carb, but that still did not deter them from trying to sell him a monster carb.
Are those guys on commission?
