305 and 350 cranks are the same stroke. I hear the 305 is lighter but have not weighed them. You can bore a 305 out to be the same size as a standard bore 350. The 307 has the same crank/ stroke as a 327.

if i was to make it a standard bore 350 then i would use 350 pistons but could i use 6 inch chevy 350 rods or would i have to use the 305 rods
how far would i have to bore it and would there be any cylinder wall left

305 and 350 rods are the same length ( 5.7" ).
Putting the 400 crank in a 305 would be a 334cid.
