When did the 305 Chevy engine come out?
The Chevrolet 305-cubic inch, small block, V-8 engine was released in 1976 as a result of Chevrolet’s search for better fuel economy. The 305 was used in various Buick, Oldsmobile and Pontiac models through 1992. It uses the small bore of the original 265 V-8 and the long stroke of the 350 V-8.
Why is the Chevy 305 a bad car?
The eight cylinder Chevrolet 305 is poorly regarded because of poor factory performance, especially when compared to Chevy’s larger 350 engine.

Can a GMC 305 be swapped for a 350?
It’s basically a direct swap. Whether the tranny will hold up or not is a loaded question and ALL depends on the health of the trans. Years ago i took the 305 out of my 77 and put in a crate 350 (before LS swaps were a thing) and I just kept my trans in it without doing anything.
