Default Perception versus Reality

Besides the engine weight, the suspension set-up (alignment, spring and sway
bar rates, shock settings, tire contact patch, rubber composition, etc.) play
greatly into that perception. I can set up my Pantera which only has 40% of
it's weight on the nose to understeer and I've taken my nose heavy Mustang
from heavy understeer to where it now is a bit tail-happy. Even the perception
of weight can be influenced by the amount of caster (lifts the weight as you
turn the wheel).

Yes. With the full aluminum treatment, you can get an FE down to weight
of your 418W. Didn't your first Superformamance Cobra have iron heads?
Could you tell any difference with the 50 lbs lighter 418W? Another data
point on the weight. An aluminum 351C (Fontana block, C302B high ports,
Roush intake, aluminum flywheel, mini-starter, etc.) came in at 404 lbs.
