There great (400/400) in the Station Wagons, as they weigh 6,000# empty. The 350/350 just doesn't "get it" at all.
The 292" is better for trucks that run "local" as it has the same torque on the 'low end' and uses less fuel on the freeway. It's easy to add some 'ponies' with pistons, 'lump ports, cam and the 4bbl too.
Happy trails.
