Joe,
Must be a 64 1/2 or an early 65. Look at what the altermator is bolted to......a generator bracket! Ford 289's with a generator were rated at 210 HP, and the alternator versions were rated at 225HP. The engine has a thin harmonic balancer, which usually is an indicator that it is a non-271HP "K" engine. But ya never know, that HP decal on the repro air cleaner sure makes it look good!
