When you mean "stock heads" you mean ported to hell right? When you say "stock block" you mean atleast a stud girdle right and ARP hardware yes? And when you say stock "Intake" you mean not that crappy plastic ones that most of the newer 4.6 SOHC cars have right? I'm just wondering. I didnt watch the video cause my computer is the suck. I also guess there are running some kind of blower at something outraguous on probaly race gas.
Not doubting it cant be done...I know it can be. There are some sohc in the high mid to low 7's already. I just dont want some guy to think he can hit 600 hp with a STOCK gt and drive it everday...saleen or not it wont happen.
Modifed stock and STOCK or two different leagues. I doubt the cams would support such hp also.
Only mustang I've seen making that much power with STOCK top end is the 03 motor....and we know that's DOHC.
