The only reason Ford went to 5W20 is for posted mileage, thin oil gets a little better gas mileage. I run 10W30 in mine because it's not stock anyway. If you have a stock engine you can still run 10W30 and have the advantage of a better safety margin. Myself I really wouldn't want to be turning 6500 rpm on 20W oil. Why do you think the GT500 runs 20W50 oil? Higher HP requires better lubrication.
Mobile 1 used to be a great oil but once it got popular they changed it and it doesn't fair very well in testing against the better synthetics.

I think Amsoil http://www.amsoil.com/storefront/rd30.aspx , Valvoline VR1 http://www.valvoline.com/products/co...ng-motor-oil/8 and Royal Purple http://royalpurpleconsumer.com/produ...!hps-motor-oil are the best for our high power engines but Pennzoil is better then Mobile 1 in the testing results I have seen. Here is a magazine article with some oils tested you may find interesting. http://www.animegame.com/cars/Oil%20Tests.pdf

Really only need a high zinc level for a flat tappet cam.
I run a ZZ4 in my 74 corvette and use Mobile 1 10w30. In my GT I run Mobile 1 5w20.
Ask a group of guys what is the best oil and you will get 100 different answers.

No flat tappet refers to an OHV type of engine, like the old 5.0, where the lifters ride on the cam and move the pushrods and rocker arms to actuate the valves. Our cars are an SOHC type and the cam followers ride directly on the cams to activate the valves. The flat tappet style requires good lubrication to prevent excessive wear.

Zink is good for all cars, it was removed because catalytic converters were mandated, it's jut not as much of a requirement in OHC motors. I don't have any other links but you can google auto oil test results and get lots of info.
