i can't recall where i saw it, but iirc the 196 is ~12 lbs heavier
than the original [heavy] 199/232/258, which can often be bored 0.125"
safely.  '65 americans used the same front springs for both 196 and
232 engines...

the '81 258 was 90-100 lbs lighter overall than the earlier motors,
but the 4.0 gained some of that weight back and continued to gain as
the block was revised.  it probably still weighs less than the
'60s-'70s sixes though, even including the '99-up iron exhaust
manifolds.
