The problem is the bore on the carb is 1 3/4" and the bore on the manifold is 1.5" It will be easier to replace the carb than the head. In researching the block numbers it looks like my motor came from a 1966-1967 Falcon. I found a carb for a falcon https://www.autozone.com/fuel-delivery/carburetor/autoline-carburetor/54003_591813_0_1277. I need to check to see what the bore size is on the Falcon carb to make sure it will fit my manifold. Also could I hook up the throttle linkage to this carb? Then I need to find a carb spacer. Thanks to everyone for all the help. I am sure I will have more questions.
