Motor and trany options

I need a new motor for my 1971 truck with 3.73 rearend. I can go with either with a 1989 350 chev truck 180,000 miles/700r4 or 1984 307 buick lesabre 90,000 miles/200r4. I do not pull anything with this truck so the power does not matter to me. I am leaning toward the Buick choice as it has less mileage. My main concern is which would be the easiest to install and get better mileage?

That 307 is going to be an Oldsmobile engine if it came from a 1984 Buick. The 350 would be an easier bolt in on the mounts. Myself I would refresh the 350 and use the 200 4r out of the Buick (200 4Rs are dual pattern usually and will bolt to BOP or Chevy).

Thanks I will use the 350 then with the 700r4 if it will bolt right in.
