I’d like to see that 429 with dual overhead cams, 32 valves and the electronics to make it work. The 4.6 (281 cu/in)DOHC is over 300 real hp in stock NA form. Add another ~150 cu/in... The new 5.0 Coyote is something like 630 hp.
Biggest problem with the BBF or FE in a car was the weight of the engine made handling less than optimal.
The car handled fine even on winding roads, the weight of the engine kept the front end on the ground when you kept your foot on the brake and put the throttle to the floor, then release brake pedal, what a thrill that was. The car handled even better when I got rid of the poly-glass wide ovals and put on T/A radials 60 series. And by the way I also replaced the original distributor with an Accel dual point w/50000 volt coil.
