Round here, in MN, anything pre muscle car era is considered a "street rod" or a "hot rod", if it has been customized/modified. Anything post 1965 is considered a "street machine", if customized.

The Back To The Fifties (largest "Hot Rod"/"Street Rod" car show in the world) allows all cars or "street rods" from 1964 and earlier.

I have a custom or "hot rodded" '65 Ranchero. I've had numerous shows that I've been stuck in "street rod" classes because of my custom paint and modified motor.

Most important, IMO, for this forum is that your car is pre 1965 (pre muscle car era) be ford boddied with ford mechanicals.

Just my $.02
