mod motors aren"t bad,just not my cup of tea.you can"t compare 1960 design windsor motors to newer mod motors.once you get all they factory none roller shit out the way and some decent heads they would have made alot more power from the factory.if you compare 1988 crown vic motor to and 88 mustang 5.0 they are the same thing.just a little bit better cam and headers.not you,but the import crow thinks that 5.0 are slow,but look at what they really where a crown vic with a better cam.if i was a ford peep back in the day fox mustangs would have cam with a 340h.p base motr and 351w 400hp as the option engine.
