Well a 307 has a bore of 3.875 and a stroke of 3.25, so to build a 350 out of a 307 you would need to bore out the 307 .125 inch to a 4 inch bore, which in most cases can not be done, and you would have to put a 350 crank which has a stroke of 3.48 inches and use 350 pistons. But if you want more cubes and power out of your 307 you can bore it .03 over, have it decked .025 inches, and use a 350 crank with 400 rods and 307 pistons to make a ground pounding 333 stroker.

Can a 307 Chevy be borded to 4inch 350 Chevy v8?
You would have to bore it .125 thousands to get it to a 4" bore. I highly doubt the 307 will take that much of an overbore and survive. Most blocks certainly can't be bored that much. 350 SBC are a dime a dozen. Better off just picking up one.
