Guide To Fox-body Mustang Engine Swap Oil Pans From Moroso

Engine swaps are popular for all Mustang platforms, and we’ve seen a wide variety of combinations over the years. When doing a swap there are a few things that can be difficult to nail down, one of which is the oil pan. This is especially true when swapping an engine that the blue oval never intended for a particular platform.

Fortunately Moroso covers a wide range of Mustang oil pans that can make these swaps easier. Since the Fox-body Mustang still remains one of the most popular platforms for enthusiasts whether they are racing, hitting the show scene, or just driving, we’ll take a look at what Moroso offers for this popular platform.

Part number 20527 fits 79-04 Mustangs with either a 302 or 351W engine.

For those going racing, doing a four-cylinder conversion, or just looking for a better pan to replace the rusty, crusty one that was bolted to an old engine, Moroso part number 20527 is an ideal choice for Fox-body applications. With 7 1/2 quarts of capacity, this pan can help keep a high volume pump fed. It also features four trap doors, and two baffles to keep oil around the sump. The kicked-out design provides good ground clearance and this one is ideal for road racing applications, street cars, or drag racers, and even fits engines with four-bolt main caps. This pan fits both 302 and 351 Windsor engines, making it ideal for those dropping in a bigger 351 W based engine.

If no replacement for displacement is your mantra, then you’ll probably need part number 20620 for that big block swap.

For the enthusiast looking to go really big in the cubic inch department, by dropping in a 460 or 460 based engine, Moroso has them covered as well with part number 20620. This pan features eight quarts of oil capacity and is a staggering nine-inches deep. Designed for dropping a big block into a Fox-body chassis, this pan will fit over the stock k-member and steering rack. It is the one to have for that big cubic-inch engine swap.

Modular engine transplants are made easier by the use of Moroso oil pan, part number 20548. This pan has a massive eight-quart capacity, but thanks to it’s side kick-outs is only 6.5-inches deep. This pan is also extremely versatile as it fits 4.6 and 5.4 liter engines in two, three, and four-valve configurations. It also fits all Mustang chassis from 1979 to present.

The modular engine swap pan allows for use of 2, 3, and 4-valve engines in any 79-present Mustang.

The modular engine oil pan also features four trap door baffles to keep oil around the sump, as well as an anti-slosh baffle. This one is compatible with a factory dipstick as well, and comes with fittings for the oil temperature sensor and a supercharger or turbocharger drain back fitting already installed. This pan is definitely a must have for anyone building a serious modular powered engine.

Of course Coyote engines swaps are all the rage these days, and Moroso was early on the scene with an oil pan solution for not only those looking to swap this engine into an earlier Mustang chassis, but also for current Coyote owners looking for more oil capacity, and a better pan. Part number 20572 is one of the newest oil pan offerings from Moroso.

This pan has many of the same features that make the Moroso oil pans work so well. There of course is the trap door, and anti-slosh baffle system, to keep oil isolated around the pickup area. Moroso also designed this pan with kick-outs to allow for extra capacity without sacrificing ground clearance.

With the Coyote being the latest and most popular engine swap today, this oil pan is one that not only covers 79-2010 owners, but also is ideal for high performance 2011 and newer cars.

The pan is also designed to be used with the Coyote’s factory windage tray, oil pump pickup, and dipstick tube. It features a thick steel rail for additional strength, and holds two more quarts than the stock oil pan. Like the modular engine oil pan, this pan features the requisite fittings for the factory oil level sensor, as well as a fitting for an oil temperature sensor and supercharger or turbocharger drain back. Also like the other modular pan offerings, this pan is compatible with all Mustangs from 1979 to present, making it a versatile and an easy choice for the hottest of all engine swaps.

Whether you’re building a car to cruise on the weekends, race down or around the track, or take to the car show Moroso has you covered.
