Gt40p heads and intake ??

[Bad Sheep]

know for stock heads and intake it is said that the gt40 and gt40p is the way to go. If that is true then why does 98 ford explorer with gt40p only make 215hp, while stock mustang gt makes 225hp. Is it ecu?? timing??

Combination of all that, plus camshaft. Those motors were setup fpr a nice flat torque curve and not all out horsepower.

Guys put them in mustangs with mustang parts and make 260-270 hp tp the wheels
