I had a 1965 Continental with the suicide doors, burgundy with black vinyl roof, had a 430 engine, originally an automatic, but I matched a Ford 4 Speed top loader in it after the auto tranny went out. The high rear end gears and excessive weight didn't lend to explosive starts, but the power band was very smooth and efficient. A carb upgrade and 100 octane fuel allowed the 430 to produce over 350h hp.The looks I got when I dragged down the main street and shifted through the gears of that lumbering hunk was priceless.
