The easiest way is to look at the Harmonic Balancer.
The 305 has a wider thicker balancer than the 350.
Pus the timing tab on a 305 is located ON the timing cover and the 350 is bolted on the with the cover bolts.

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.
No. The bore size is different between a 305 and 350. The 350 bore size is larger.
If the Buick 305 is really a Chevy 305, then the motor mounts will interchange with a Chevy 350.
5.0L is a 305. 5.7L is a 350
The headers for a 350 and 305 are the same.
If you are asking if you can substitute a 350 for a 305, the answer is generally yes.
Oldsmobile used Chevy 305's. 76 350 rocket 77 305 Chevy
Depends on how the motor is set up.
a Chevy 350 crank is a Chevy 305 crank. they have the same stroke, 3.48 inches, and are interchangable. swapping between the two cranks does not change the engines displacement
the block & heads are the same you just have to pull the 305 out & put the 350 back in
Primarily the bore size. The 305 has a bore of 3.74 and the 350 is a 4.0 bore. They share the same stroke on the crank. And no, you can't bore a 305 to a 4.0 bore.
No they are not.
