mrm1957: the current modular motors often referred to as a mod
motor is totaly new to the ford family, but not to say that a cammer is new to ford. The old 427 is a legend in our time. The
current cammer is a whole new animal in the ford stable. These
mods 4.6,5.4,6.8 V-10 are modular as they share pistons, cranks,cam designs, valvetrain etc. Even the 4's & V-6's share the mod theory in essence, a 4 cyl is half of a 4.6 V-8. The V-6 is a 4.6 with the rear two cylinders choped off. The 5.4 is a 4.6 with a longer stroke. The V-10 is 5.4 with two cylinders grafted on the back of the block. Henceforth, modular, now if memory serves me correct, all mod motors have a crank driven oil pump. Which is virtualy bulletproof by design. The heads are a mechnical work of art, from port design to valve gemotery. Not to mention the ability to rev the valvetrain without floating the valves or getting asthmatic at high rpm's. [the previous weaknesses of the old
pushrods are valve floating,port design, etc.] I have seen some engine builders claim their buildup can achieve in excess of 500+hp & still remain a decent daily driver or very streetable.
The old pushrods have served ford admirably for years.

They are the way of the future.
I am not knocking the 1950's designed pushrod V8. It has served us well, and the power that my 5.0 has in the old Stang is awesome!!
But , like everything, eventially something new and better comes along. (Mercedes has had OHC V8's since the early 70's). I know that Ford had the 427 SOHC engine, but it wasn't mass produced.
My 5.4L does a good job considering that it is only 330ci.
If Ford would come out with a 6.6L (400ci) Mod motor, that would be great!!
