off the top of thier head does anyone know how similar the stock 91ish mustang H.O cam is to the 96ish explorer 5.0L cam ? i used to know this crap but i am getting old and senile i guess.
Much as I'd like to update the intake these mods are being done to a 351 in a full size Ford van and no aftermarked or Ford intake fits except the OEM one.If you look at the Ford data sheet up above you'll see that Ford sped'd the Cobra cam for the heavier Thunderbirds and Cougars in the early/mid 90's. They're data indicates that the Cobra cam made a bit more low end torque than the HO in the same set up. If you have access to one - I'd use it in your application. Also -- the relatively heavy Explorer did just fine on bottom end grunt with the Explorer/GT40 intake. It should offer torque/hp gains all across the tach compared the restrictive stock unit. You should end up with a motor that makes great torque from idle to 4500-5000 rpm.
