STOP.
before you go any further make sure of two things.
one. passenger side exhaust manifold might use the broad spaced rear outboard hole on the passenger side. you can use the earlier manifold in place of the late, but you will have to redo that section of exhaust.
two. flywheel bolt pattern between the two may be different. 307 iirc is an external balance motor and the flywheel may be unique. the number of teeth on the flywheel ring gear will determine what series starter you need.
the 307 was a low compression, low hp and low Nickle block. Putting one in a Suburban may not get you a MPG improvement over a 350 because the 307 would be working harder to move the same amount of weight. All SBC's are internally balanced except for the 400.
