I managed to make 360 horsepower at the flywheel(mathematically derived, not actually dyno horsepower), with a 68 327/250 horse engine. That one has only 8.5 to 1 compression,has small valve heads, and has a shorter stroke. The 350 should make a lot more torque, has way better ports and valve sizes, and it should be good for over 400 horsepower if it's a good one. The size and weight of a wagon is the biggest thing that has to overcome. It's been done. If the big block is really your preference, Herman Chapman had a 402 Chevelle wagon in Super Stock(no manifold restriction,open season on camshaft selection), maybe that would be an option.
