The key words mentioned were "modified to make more horsepower".
There were stock muscle cars like the Shelby Mustang GT-350. Or, you could take your average notchback Mustang and install all the GT-350 engine and chassis upgrades and turn it into a muscle car. Your average 1965 Mustang with a small V8 might not have been considered a muscle car.
Let's keep in mind that Ford offered a lot of engine options in the 60's. Not all V8's are created equal.
Straight-6
289-V8 (older)
302-V8 (newer)
302-V8 Boss (Trans Am engine)
351-V8
390-V8
428 Cobra Jet
429 Boss Hemi
Ford also made a 460 cubic inch engine that went into a few full size cars back then.
Your budget was the limit.
