I got an engine. A 289 apart, but it has some interesting parts. One is a Holley 4B carb. The instruction sheet that came with the carb shows it as a 4150. One feature is a center fuel inlet that the prior owner suggested was some sort of racing carb that won't starve for fuel on RH or LH turns, etc. The instruction sheet say's it fits: "65-67 Mustang 8cyl, Cobra, GT350 289 eng. Some writing on the sheet has a P/N: CT-195A and Ford #C822-9A586-E Does this make any sense to you? I'll tell you a good story about the motor when I have the time. Thanks in advance for your interest and help.
