The Chevy 350 and 305 engines are both small block engines and they share many of the same components, including the distributor. The 350 and 305 distributors are both 8-cylinder distributors, so they have the same number of ignition points and they rotate at the same speed.
However, there are some slight differences between the 350 and 305 distributors. The 350 distributor has a slightly longer shaft and a different gear ratio than the 305 distributor. This means that the 350 distributor will need to be adjusted differently than the 305 distributor in order to properly time the engine.
Overall, a Chevy 350 distributor can be used in a 305 engine, but there are some slight differences that will need to be taken into account when installing and adjusting the distributor.
