modular?

Blownstang450 · Jun 23, 2004

hey guys im a newbie and ive been reading up on mustangs for quite some time...my brother had an 02 GT and an 03 Cobra and he is the one who got me hooked on mustangs...anyways i always click on the Modular 4.6 forum and i just want to know what is 'Modular' referring to?

Modular2v · Jun 23, 2004

Most of the time the modular is reffering to "interchanging parts" for example the 4.6 is interchangable with the 5.4 ex: HEADS, bearings etc....

bdcardinal · Jun 24, 2004

ya, there are a lot of parts that are interchangable. heads, cranks, rods, pistons, can be interchanged within the years.

And even platforms .... Explorer, Aviaitor, Mark VII

Welcome. Hope we can answer your questions, and represent the best side of the Mustang family.

werent some of the parts on the 5.0/5.8 interchangable also?

Yes you could swap the heads out on the Windsor 351 motors.

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

I believe chevys 350 is not a modular engine it is a pushrod engine.

He was just saying the Chevy 327/350 and the 454 have the same basic architecture.

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?

bdcardinal · Jun 29, 2004

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.

thanks bdcardinal, thats exactly what i was looking for

Was a ford DOHC v10 ever made?

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?

jasonh_86 · Jun 27, 2006

You're probably smoking crack.. damn hippies

Indeed it was.. In limited numbers.. Here is a quote from Motortrend:

If you do the math, this all-aluminum, DOHC V-10 based on the current Modular 4.6 comes out to be just a smidgen under 351 cubic inches. That's why this silver rocket-launcher proudly and appropriately wears Boss 351 decals in the best '71 Mustang tradition. On a chassis dynamometer, its clandestine motor is said to deliver 430 horsepower and 405 lb-ft of torque to the rear wheels.
