Oil pan baffle and scraper

An oil pan is a reservoir for the engine's oil, designed to hold the amount of oil needed to lubricate the engine when it is running, plus a reserve. The oil pan also helps to cool the oil through its contact with the outside air.

The oil pan baffle and scraper are crucial components in maintaining optimal engine performance. The baffle ensures that oil remains controlled above the level of the oil pump pickup screen. Its ribbed design prevents oil from flowing forward during deceleration and further restricts movement within the crankcase. This is particularly important in preventing oil starvation in the engine's crankshaft main bearings.

The scraper, often referred to as a crankshaft scraper, works in conjunction with the baffle to regulate oil flow. It helps to protect the rotating assembly by keeping the oil off it, allowing the crank to rotate smoothly and the engine to gain more power.

For a 351C Speedmaster engine, the use of an oil pan with an effective baffle and scraper system is essential. While specific recommendations for this engine configuration were not readily available, some options in the Speedmaster range include:

• Speedmaster Ford 302 351C Cleveland 7Qt Drag Front Sump Unplated Oil Pan
• Speedmaster Ford 351W Windsor 7Qt Fabricated Drag Front Sump Oil Pan & Pickup SVO Block
• Speedmaster Ford 351W Windsor 7Qt Fabricated Drag Front Sump Oil Pan SVO & DART Block

It is worth noting that some oil pans may require slight modifications, such as dimpling, to accommodate the longer main studs associated with a girdle.

Oil pump options

When it comes to oil pump options for your 351C Speedmaster main girdle, there are several factors and modifications to consider for optimal performance and engine longevity. Here are some insights and recommendations to guide you through the process:

• Stock Oil Pump: For a street performance engine that will not frequently exceed 6000 rpm, sticking with the stock oil pump is generally recommended. The stock oil pump is designed to provide sufficient lubrication and should be adequate for most modest street combinations. Deviating from this can lead to unnecessary complications.
• High-Volume Oil Pumps: While high-volume oil pumps might seem appealing, they can actually cause more harm than good. High-volume pumps can lead to premature distributor gear wear and even engine damage. Unless your engine is solely dedicated to drag racing and spends its entire life at the dragstrip, it's advisable to avoid high-volume pumps.
• Oil Pump Driveshaft: Investing in a heavy-duty oil pump driveshaft, such as the ARP 1547905, is a wise decision. This component is designed to handle the torque requirements of increased capacity oil pumps or heavy viscosity lubricants. It's an extra layer of protection against expensive engine damage.
• Oil Pump Shim: If you're considering shimming the spring on your oil pump, exercise caution. Ensure that the shim is properly installed and does not hinder the free movement of the bypass piston. It's also crucial to verify the clearance and fit of the cup to prevent oil leakage.
• Oil Pressure and Bearings: Aim for an oil pressure of around 60 psi for high-performance street engines. Regarding bearings, fully grooved main bearings are not ideal for high-revving engines as they reduce the size of the oil wedge under the crankshaft. Partially grooved bearings are a better option.
• Oil Gallery Plug: Drilling a small hole in the oil gallery plug near the distributor shaft can improve oiling to the cam gear. However, be mindful that a hole larger than 0.020 inches is unnecessary and may lead to excessive oil spewing.
• Oil Pump Modifications: Before installing an oil pump, it's beneficial to mock-up the distributor and ensure it's properly seated. This helps prevent issues with the distributor driveshaft being too loose. Manually running a few quarts of oil through the pump before installation is also a good practice.
• Lifter Bushings: Installing lifter bushings can be a significant improvement for the 351C's oiling system. They help address oiling concerns and are a more comprehensive solution than simply relying on high-volume oil pumps.
• Oil Restrictors: Using oil restrictors in the cam bearings is another important modification. This helps manage oil flow and ensures adequate lubrication without excessive pressure.
• Oil Pan: Opting for an upgraded oil pan with a larger capacity, such as a 7-quart pan, can provide benefits. Additionally, look for pans with effective baffles or anti-slosh plates to minimize oil starvation during high-performance driving.

Remember, the key is to strike a balance between sufficient oil pressure, flow, and lubrication without resorting to excessive measures that can lead to premature wear or engine damage. Always research and understand the implications of any modifications before proceeding.

Oil pan capacity

The oil pan is an essential component of your engine, serving as the reservoir for the oil that lubricates and cools the engine. While it is important to have enough oil, overfilling the oil pan can also cause problems.

The amount of oil in your pan should be sufficient to lubricate the engine and provide a reserve. However, too much oil can lead to "windage", a turbulent environment of oil and air that creates parasitic drag on the engine, reducing its power. Additionally, excess oil can result in higher oil temperatures as it is continuously splashed around the crank and cylinder walls.

On the other hand, not having enough oil can also be detrimental. Drag racers, for instance, may opt for lower oil capacity to maximise power, but this comes with the risk of engine damage due to insufficient lubrication.
