i bought a 2000 merc sable a few months back when i thought about the dohc engines i have had i thought about putting a duratec simpley cuz it was the dohc option for my car but i have recently been hearing once i looked into it that the sho engine would be easyr to do so i guess is i would like to know rlly what im gainin by switching to the sho instead of the duratec performance terms
