307 pistons are 3.875" diameter. 305 pistons are 3.736". It might be possible to bore a 305 large enough to accept the 307 pistons, but the wrist pin location would be .230" off because of the different stroke. In short, no.
A 305 chevy engine has a bore diameter of 3.736". Check the diameter of your L2256 piston to see if it is that size.
No, 350 has a substantially larger bore.
the pistons are the same diameter. no they are not the same diameter, the bore on a 305 is smaller than a 350
BORE is 3.740 and the stroke is 3.480
yes
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. The bore size is different between a 305 and 350. The 350 bore size is larger.
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 stroke is---3.740 bore and 3.480 stroke. STOCK 305
