Then the Coyote engine has been out for awhile and the HP it makes is pretty impressive. A 4 valve head gives the engine great low end torque for it's small displacement size.
Could you imagine what a 500 cube engine with a good set of 4 valve heads could do to a set rear tires.........
Now given these engines handle supercharging really well and make over 800+ HP that kinda puts the engine back into the unusable for road racing with too much power out of the turns.
Perhaps without realizing it, you contradicted yourself. The 5L mod makes close to 500HP IF measured the exact same way you'd measure a dyno'd 500 Mopar. 444HP net easily does that. Thats without headers, and the odd other common as-installed' bolt-on.
Take a theoretical 500cid Coyote and you'll have 800HP, and as you say, unusable power.
NO need for 500cid anymore. That was for back when engines made 1HP/cid. Every supermegabadass car in America does plenty fine on under 400cid, most well under. Take these new engines out ov their obese and mandate-addled carrying cases (Mustang included) and drop 'em into prepped older cars and you'll have all the speed you can handle in 99% ov cases. The only thing 500cid is a surefire recipe for these days is a car that never gets driven.
