american manufacturers like the modular idea when it comes to engines. ford has their modular 4.6/5.4/8.6, and the windsor family 260/289/302/351W, plus the FE's and the big blocks. chevy has the 327/350 and the 454. it makes everything cheaper to manufacture when the same basic architecture is used on on their motors. the cool thing about the ford modular motors is that you have both sohc and dohc head options as well as iron and aluminum blocks.

I think the term "modular" referrs to how each cylinder in the block is "self-contained" so to speak. Each cylinder has it's own oiling, cooling system and allows for cylinders to be added/subtracted without re-designing the whole engine. You can get different engine configurations just by adding/removing cylinders.
That's what they did with the (newer) BOSS 351. It's essentially a "cut-and-paste" engine. It's identical to a 4.6 modular just with 2 cylinders pasted in the back. Same with the heads, crank, etc...

skud that could also be used as the definition, good point!!! At first when i saw the boss 351 i thought they were referring to the v10 used in the trucks with customized DOHC heads! i later read it to find out that it was a 4.6 with 2 cylinders pasted on and 4.6 dohc heads that were also customized for 2 more cylinders! I kind of felt stupid even thinking it was the v10 (6.8L) used in the trucks because a 351 would be equivalant to a 5.8

not to hijack, but can someone explain the difference between modular and pushrod in definition. I know very little about the pushrod engine and still relatively little about the modular. Could someone shed some light on this for me?
pushrod engines have the camshaft in the block. the camshaft pushes on a pushrod, which pushed on a rocker arm which opens the valve. its a really good design for compactness. 99.9% of the pushrod motors are 2v. the modular motor is fords foray into ohc motors. the cam is moved to the heads and there are wither 2 or 4 cams. modular is just what ford called its ohc v8's and v10's. ohc motors are usually more complicated to manufacture and assemble and in turn cost more. the ohc v8's are physically bigger than their pushrod counterparts, even with smaller cubic inch displacement. if you've seen a bare 4.6 block you would know its rather small, but the heads are big. the SOHC heads are closer to a more normal pushrod head, however the DOHC heads are really rather large.

modular is just refferring to how ford can design motors to be interchangeable.
pushrod is refferring to a motor where pushrods are the part between the cam and the head, the cam is in the block valley and the pushrods rest on the lobes which transmit their force up into the head which presses on the rockers. most manufacturers have switched to OHC(over-head cam) in which the cam directly contacts the rockers.

doesnt it also have something to do with the way the tooling can be quickly changed out at the manufacturing plant to produce a 4.6 or 5.4? Did I read that somewhere or am I smoking crack?
