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
All the dimensions are the same, but it should be re-balanced for the lighter pistons.
no.
If you are asking if you can substitute a 350 for a 305, the answer is generally yes.
They are basically the same heads, If the 93 350 is a vortex motor.
Yes
yes it will
yes
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.
engine will fit, but 305 tbi will be too lean for 350 It'll burn up
305 is the same distributor as a 350 will even fit some big block chevy's.
