Physically, they are the same exterior dimensions, but that's about it. Bore and stroke are different, rod journal diameter is smaller on the 283, heads bolt on, but no accessory mounting holes in 283, balancer is different. Carb and intake would interchange, distributor fits, bell housing bolt pattern is the same.

No, Ford has never built a 283. The 283 is a Chevy engine.
A bare 283 Chevy engine block with no heads or rotating assembly, aprox 150 lbs.
The Chevy 283 engine has the standard bellhousing configuration and is compatible with transmissions that bolt to first generation small blocks. The automatic TH350 transmission will fit the 283 engine.
