Nope, not afraid of it and don't think it is junk - I've owned two and built one. I have one now in my truck.
But the motor is something of a conundrum in some applications. Take my Lightning for example.
It is a SOHC engine, 2V per cylinder, with a supercharger and displaces 5.4L. Due to the rod ratio it doesn't want to rev much. The 5.4L mod motor in the Lightning can't take advantage of the SOHC valve train advantages, it is far larger than a pushrod setup, and it is heavier to boot.
The SOHC mod motor is physically much larger than an equivalent 5.4L SBF or 6L SBC, both of which can rev higher and are much smaller - even with positive displacement superchargers in the intake valley.
Do I hate it? No. The truck is my daily driver, makes over 450 hp at the wheel and 525 ft-lb torque, and will haul ass. But I could easily achieve that with a LT1 style motor and blower, LS1 motor and blower, or a SBF motor an blower - positive displacement blowers are all I'm considering for this discussions' sake.
But I still wish Ford had continued the pushrod engine design and had a modern pushrod motor to offer. I think time will show the pushrod design is superior for hp per cubic ft and weight of the said engine. Have a look:
