Well, one of my past jobs was at a engine rebuilding workshop, the 351's which I built (with similar spec to a phase 3) could not produce more than around 330hp.
In fact my old boss at the workshop had seen phase 3's on the dyno (he's an old bugger) back in the early 70's and his reports were that they were good for around 330hp. With the GT being good for 300hp.
I remember reading about this discrepancy also, as Ford rated both the GT and GTHO at 300hp, however who drove the 2 cars knew the HO had about 30hp more.
The only reason it dosnt return a higher top end speed is because of its 6150rpm rev limiter.
No, I'm talking about terminal speed over 400m, so the limiter will not be a limiting factor as the phase 3 only reached about 155-160kph.
Current Falcon GT's reach close to 170kph over 400m, and they are nearly 200kg heavier. Even current XR8's hit just over 160kph.
400m terminal speed is a pretty indicator of HP.
The Phase II happily hit just under 8000rpm. Remove the limiter from the Phase 3, and you get your answer.
No, phase 2's suffered from valve bounce above 6000rpm, that's why they fit solid lifters in the phase 3 so it could pull more revs.
In any case, neither engine will pull 8000rpm, Clevelands with the standard rod length struggle at anything past 7000rpm, I know, because we drag raced a 450hp Clevo for many years and it never pulled more than 7000rpm.
Actually, as much as I love the BA GT, the old GTs are much more than half the car they are. Certainly closer than anything else you can spend cash on.
This is just personal prefference and way off topic, so I won't go any further there. Horses for courses and all that.........
