You may be overlooking one or two other engines my friend; such as the GM 3800.
Have that motor in my Bonneville. Yes, it is a good powerplant. Ballsy, quick, and with 110K miles on it, it’s still a beast.
But for longevity, ease of maintenance, horsepower and simplicity, I’ll still have to go with the Ford 289.
The 3800 is a good engine, but you gotta keep a close watch for any coolant leaks snd change the thermostat from time to time. if it overheats, may as well use it as a boat anchor
