That was my thought too. Most owners who are inclined to modify their cars seem to go for the supercharger as opposed to more complex methods. As gear heads, we all know that power is made in the heads. I have been disappointed in these hi tech modular engines from the git-go because of their modest power output, though the ones hitting the streets now are respectable. Why wouldn't tried and true hot rodding teqniques work? We all know the bolt-ons work. I understand our Bullitts have the "Power Improved" heads shouldn't it be a relatively simple matter to improve the power more, as you point out, with cnc porting, valves and springs, port matching, etc. Is there maybe not enough metal in the heads for this kind of thing? Have the experts just not turned their attention to the 4.6 yet?
No offense to anybody, but IMHO, muscle/pony cars should be naturally aspirated (maybe some Mustangs are an exception because back in the day, some supercharged ones hit the streets with factory warranties). I wouldn't even think of supercharging 4165, but being an HP junkie like the rest, need more. I just want to do it the hard way
