HO cam vs F150 cam
Reply #1 –
That cam has the same exhaust duration as the HO cam, but 20* less intake duration...it's the same cam that's in the Explorers and their peak power is *claimed* to happen around 4200 with "P" heads.
If you're using stock E7 heads, it may fall off a little sooner than 4200.
Good luck,
