buying a 67 coupe

yeah you can but you'll have to change the whole front end and drive train, 6 banger mustangs all used lighter duty stuff than what they put in em for a v8.

If this is your plan, you will be many dollars ahead by getting an original V8 car. Too many I6 parts to change out on that one to make it worthwhile.

what L said. search the forum for the plentiful info on 6 to 8 conversions.

Don't ask me why but the "sticky" for a 6-to-8 swap is in the talk section, read up on it. They are right of course that a V8 Mustang had many things different on it than the motor. All suspension components and braking components were different. The transmission and rear axles as well. If you follow the pattern of many here when you build up your car with big power you'll probably be replacing that stuff anyway, EVEN IF you had V8 components to begin with, I know I did. Because of that I have an entire 289/C4/8" drivetrain sitting in my garage taking up space!
