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.
To differentiate between a 1968 283 and a 327 engine, you can check the engine's casting numbers and the size of the engine's displacement. The 283 has a displacement of 283 cubic inches, while the 327 has a displacement of 327 cubic inches. Additionally, the 327 typically has larger intake and exhaust valves compared to the 283, which can also help in identification. Lastly, the engine's identification tag or code, usually found at the front of the engine block, can provide specific details about the engine model.
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.
