Subtract 305 from 350 and that will give you the difference (or interval) between the two numbers:- the answer is 45.

However, if you mean what is the difference between a Chevy 305 and a Chevy 350, then it is the difference between the engine bore (the cylinder) sizes. The 305 bore is 3.740 inches. And the 350 bore is 4.000 inches, giving the Chevy 350 20HP more then the Chevy 305.

The bore and piston size are the only real difference between the two.The 350 has a bigger bore and piston and so puts out more horsepower, the305 = 3.75" bore and the 350 = 4" bore. Both have the same stroke.Also the starters are different because of the smaller flywheel but other wise the external parts are interchangeable.

What is the difference in a 305 and a 350?

The 305 & 350 are basically the same engine. The 305 just has a smaller bore(3.736 vs. 4.000), not quite the power or torque, but durability should be almost identical. It is more costy to rebuild a 305 than a 350 due to the popularity of the 350. If power is not an issue then go for the 305 if you can get one cheaper. If you want more power, then a 350 is the way to go.
