I know i have always wondered, so i figured i would post what i have come across. Sorry if it has been posted already. If not, then sticky???


In 1996, Mustang GT and Cobra got their first 4.6L SOHC and DOHC engines. In 2005, Mustang GT got 3-Valve SOHC power. Isn't it time you knew more about the engine Ford spent more than $1 billion developing to make Mustang the most advanced pony car ever?

Here are some of the Ford vehicles that use 4.6L Modular engines:
# 4.6L SOHC Engine introduced in '91 in the Lincoln Town Car
# '92 Crown Victoria and Grand Marquis 4.6L SOHC
# '93 Lincoln Mark VIII first to get 4.6L DOHC
# '94 Thunderbird 4.6L SOHC
# '96 Mustang GT and Cobra 4.6L SOHC and DOHC
# '97 Ford F150 and Expedition 4.6L SOHC
# '98 E-Series Vans 4.6L SOHC
# '99 6.8L SOHC V-10 introduced in new Super Duty trucks
# '00 Ford Excursion
# '02 Ford Explorer and Mercury Mountaineer 4.6L SOHC
# '03 Lincoln Aviator 4.6L DOHC

Basic Modular Engine Facts
There are two Modular engine plants in North America - Romeo, Michigan, and Windsor, Ontario. Romeo is the old Ford Tractor plant. Windsor has been producing Ford engines since World War II. Although Romeo and Windsor Modular engines look the same on the surface, they are different inside. Here are the basic differences in Romeo and Windsor engines:
# Romeo was the only Modular engine plant from '91-'95.
# Windsor came on line for '96 to build 4.6L and 5.4L SOHC engines for trucks and vans
# Although Romeo is primarily a car engine plant, it has produced Modular engines for trucks
# Although Windsor is primarily a truck engine plant, it produced Modular engines for '99-'00 Mustang GT
# Romeo engines employ different blocks, heads, and cranks than Windsor although they look similar
# Most Romeo blocks are marked with an "R" in the casting
# Windsor blocks are all marked with a "W" in the casting in two places
# Romeo heads employ bolt-on cam journal girdles
# Windsor heads don't have cam journal girdles, just individual journals
# Because Romeo and Windsor engines have different timing cover/cam cover bolt hole sizing, it is best to use Romeo heads and blocks together and Windsor heads and blocks together
# Romeo blocks have jackscrew cross-bolted main caps
# Windsor blocks have dowel pin cross-bolted main caps
# Romeo engines have primarily six-bolt flywheel/flexplate flanges
# Windsor engines have eight-bolt flywheel/flexplate flanges
# Oil filter/cooling neck types vary depending on vehicle type
# Timing cover depends on vehicle type
# Romeo cam sprockets are zero-fit and slip right on
# Windsor cam sprockets are pressed on
# Romeo cam covers have 11 bolts
# Windsor cam covers have 13 bolts
# Difference timing covers for SOHC and DOHC
# Same basic timing chain/sprocket system for both SOHC and DOHC
# DOHC engines have secondary timing chains for secondary camshafts
# SOHC has a standard oil pump and DOHC has high volume

Cool info. Isn't there also a way to check which one you have by looking at your VIN?

I just put a windsor timing cover on a romeo block and romeo heads so it does work.

Did you know that!? the Teksid block in the '93 Lincoln Mark VIII, and cobras from 96-99 and even early 2001 is made by... well Teksid! The company who currently or recently made blocks for Ferrari.

Now you know!
