Re: 4.7L H.O. Engine self destruct
Could have had a defective piece that finally let go. My friend had his lifter bore break right off the head. There was probably to much detonation that made it do that. It usually is the piston ring that breaks apart on these 4.7's with too much hard driving, detonation, boost or nitrous. They have aftermarket pistons available now and heads also.
Supercharged 4.7L HO. If you would like to know more just ask.
