An empty garage space is sacreligious. You will be swapping the eng/trans so no issue there. Just go over the body with a fine tooth comb like you have for rust & PRIOR COLLISIONS. I'm assuming the vin #/title are in order. No caveats, just evaluate it with a critical eye. subframes need to be solid. fenderwells/floorplans/trunkwell. Kmember is the same /6/v8 & you can even swap a B bigblock into it easily with streetmaster mts if they are still in business or fab your own. EDIT best would be a 360 or even better a stroked 360 & 4" cranks are cheap nowadays & the KB pistons ain't too bad.
